   surefire手電筒新手購買入門必備資料
   
     如果您需要購買一個手電的話,必然有需要它的理由.一個好的手電,並不必然就是一個貴的手電,也不必然就是一個做工好的手電。隻有適合自己使用的,才是最好的。
   
     為了讓不是很體味LED手電的新手能快速找到適合自己的手電筒,下文將從你采辦手電的目的和要求來寫。你隻需按你的要求來找到年夜問題,就可以找到你所需要的並適合你的筒子。
   
     一般電筒首要有以下用途:
   
     一.走路照明用手電
   
     屬最常見用途,年夜多用於夜晚上下樓,晚班下班途中或外出時才帶上,僅用作走路時的照明,一般來說要求泛光充沛,亮度中等,顯色性好。對筒子的要求不高,選擇規模很廣.本店年夜年夜都的電筒都能知足這種要求.
   
     1.筒子類型:可以用18650直筒或是AA筒子.
   
     2.要求達到的亮度:平展年夜道上走路對亮度要求不高,一支功率1W以上的AA筒子足夠了.假如是村子的土路或是山區山路,最好得用18650筒子。
   
     3.LED的光色,在路麵幹燥的情形用白光的LED就行了,假如是山區或是在濕滑的情形下,最好是用熱白或是自然白的LED以增添顯色性,同時,能有功率年夜點的筒子就用年夜功率筒子,事實平安最主要。
   
     4.電路要什麽檔位:單檔或高,中,爆閃三檔。爆閃首要用來提醒人和過馬路時用的。
   
     5.用什麽光杯:因為要求泛光好,所以舉薦用桔皮杯,而且最好要淺一點的桔麵杯。之所以要用淺一點的原因,不單是指淺一點的相對不聚光,還指LED發出的光線能有更多的光線是直接射出不經由反光碗反射出往的。不經由反光碗反射的益處是,桔皮反光碗的效率較低,有的隻能達到70%擺布,所所以不經由反射會亮一點點。當使用的筒子功率較小的情形下,本人不建議用桔皮杯的筒子,而用反光率更高一點的光麵杯筒子,當然是指淺一點的光麵杯。
   
     6.要求達到的外不美觀措置:按小我快樂喜愛而定。
   
     7.要求防水機能:能防年夜雨衝淋即可。
   
     8.價位:按小我經濟實力,一般選擇中低價筒就夠用了
   
     二.EDC用(EDC的意思是天天隨身帶,以備不時之需)
   
     1.筒子類型:EDC當然要求便利攜帶了。按要求分歧,對筒子用的電池和體積也有所分歧:最便利的是AAA;最亮和最遠射是16340,各方麵機能都不錯而且最便利買電池的是AA;續航時刻最長的是直筒18650筒子。
   
     2.要求達到的亮度:EDC用的筒子和日常平常走路的筒子有良多配合點,所分歧的隻是在達到四周機能的情形下,要求必需足夠小以便利攜帶。所以小我覺得EDC的筒子要求比走路用筒要高得多。EDC還有一個特點就是在年夜部份時辰隻需亮幾秒鍾或是幾分鍾,而不必考慮長時刻點亮時的發燒.所以,要求亮度高的自然是用鋰電最好.一般要求就用AA或AAA.
   
     3.LED的光色:用白光即可。
   
     4.用各類電池的續航時刻:追求高亮,就用各類鋰電池。在LED耗損功率3W,電流750MA時,各類鋰電池繼航時刻:18650的續航時刻在三小時;16340或是14500續航時刻在1小時;15266或是10440續航時刻在20分鍾;追求中等功率而且通用性好,就用所有小店裏能買到的通俗電池。用可充AA電池,放電電流2A擺布時,續航時刻約1小時;用高質量的容量達到2200MAH的堿性AA電池,放電電流在1A擺布時,續航時刻約在近2小時(假如用2A電流放電就很不經濟,往往隻能高亮半個多小時);用垃圾AA電池時,1A放電也不經濟,最好用500MA電流放電,續航時刻能達到約2個小時。
   
     5.用什麽電路:18650筒最好用7135組成的恒流電路,不建議用升壓電路,原因是7135的電路最不變,效率高,7135恒流電路的錯誤謬誤是當電壓低到必然水平時,越用亮度越低,這個錯誤謬誤在EDC時往往是利益:誰能保證當你正需要用電筒時,你的電筒的電正好是充沛的呢,當你的電量很少時,7135的電路正好能供給很暗的光,至少能對於一下吧。對於AA筒子,那隻能用升壓電路啦,最好用質量好效率高的,以節約電量達到延遲續航時刻的目的。
   
     6.電路要什麽檔位:高,中,低,爆閃,SOS,用得最多的仍是高,中二檔。
   
     7.用什麽光杯:頭部直徑年夜的,好比直筒18650和用16340的,舉薦用淺一點的桔麵杯。之所以要用淺一點的原因,不單是指淺一點的相對不聚光,還指LED發出的光線能有更多的光線是直接射出不經由反光碗反射出往的。不經由反光碗反射的益處是,桔皮反光碗的效率較低,有的隻能達到70%擺布,所所以不經由反射會亮一點點。當使用的筒子頭部較小的情形下,好比AAA的筒子,建議用反光率更高一點的光麵杯筒子,好的光麵杯子在AAA上也能在近處聚成一個光斑,有一個亮的光斑仍是鬥勁有用的。
   
     8.要求達到的外不美觀措置:要耐磨的最好,好比不鏽鋼的或是HAIII的.
   
     9.要求防水機能:能防年夜雨衝淋即可
   
     10.價位:按小我經濟實力,一般選擇稍貴一點的筒子,事實是成天跟著自己的,操作率高,當然得用好點的。
   
     三.戶外搜索用(狩獵或戶外勾當等,需要高亮,必需遠射)
   
     1.筒子類型:必需用18650年夜頭(功率年夜,亮度高,能遠射,繼航時刻1.5至3小時);假如不要泛光和不用高亮度,不需要好光斑,可以用調到光斑極小的透鏡手電。
   
     2.要求達到的亮度:良多都是對LED進行超頻使用,電流往往要達到LED的使用極限,用18650筒子,電流達到1000MA的算一般,達到1200MA的就是接近Q5的LED的極限了,因為再增添電流時,發光強度增添的很小,可是LED壽命年夜減,所以不建議跨越1200MA。這時,LED耗損功率達到4.5W擺布。
   
     3.LED的光色,在情形潮濕的情形下,最好用熱色的LED,在幹燥的情形下,最好用白光LED,因為白光比熱色的要亮。
   
     4.各類電池的續航時刻:追求高亮,用18650年夜頭,功率3W,電流750MA的筒子是最低要求,續航時刻在三小時;電流1200MA,功率達到4.5W,這是Q5的LED的極限了,因為用了升壓電路,LED的電流1200MA時,電池端的電流就可能達到1.2至1.7A,續航時刻在1.5小時。
   
     5.用什麽電路:當然用的18650鋰電池,可是Q5的電壓高,當電池在3.7V放電平台時就不能有足夠年夜的電流供給給LED了,所以一般要用升壓電路,最好用質量好效率高的,因為高亮檔續航時刻短而且不經濟。
   
     6.電路要什麽檔位:高,中,低三檔和五檔。
   
     7.用什麽光杯:因為要求泛光少點,一般是用鬥勁深的年夜口徑光麵杯。
   
     8.要求達到的外不美觀措置:一般要求筒子是黑色的。
   
     9.要求防水機能:至少能防年夜雨衝淋,因為有時要涉水,所以一般要求是能在筒子高溫時泡冷水裏也沒事。
   
     10.價位:按小我需要達到怎麽樣的遠射機能而定,為達到高亮度和超強的遠射機能,一般選擇中高價筒假如在亮度和遠射機能及外不美觀等方麵有所妥協,就完全可以用中低價筒子。
   
     四.車載用(永遠放在車上,有用時能隨手拿到的筒子)
   
     1.筒子類型:建議用直筒,可以用18650直筒(功率年夜,亮度高,繼航時刻約3小時),或是較年夜功率的AA筒子直筒(電池處處可買,攜帶便利,繼航時刻約1小時)。
   
     2.要求達到的亮度:假如用18650筒子,電流達到750MA,LED耗損功率達到3W擺布就行了,假如用AA最好用電池端能達到2A電流的檔次高點的AA。
   
     3.LED的光色,假若有時要走路用或是修車用,仍是用熱白鬥勁合適。
   
     4.各類電池的續航時刻:用18650鋰電池,功率3W,電流750MA的筒子續航時刻在三小時;用可充AA電池,放電電流2A擺布時,續航時刻約1小時;用高質量的容量達到2200MAH的堿性AA電池,放電電流在1A擺布時,續航時刻約在近2小時。
   
     5.用什麽電路:18650筒最好用7135組成的恒流電路,強烈不建議用升壓電路,原因是7135的電路最不變,效率高,7135恒流電路的錯誤謬誤是當電壓低到必然水平時,越用亮度越低,這個錯誤謬誤在沒電而強烈需要電筒時反而是利益。對於AA筒子,那隻能用升壓電路啦,最好用質量好,出格是在長時刻震動後靠得住性高的,以確保隨時能用的目的。
   
     6.電路要什麽檔位:高,中,低,爆閃。爆閃是必需的,主若是在修車時可以起到提醒後車的目的。
   
     7.用什麽光杯:因為照的往往是近距離,假如光斑太集中反而看不清,所以要求泛光很是好的,所以舉薦用淺一點的桔麵杯。之所以要用淺一點的原因,不單是指淺一點的相對不聚光,還指LED發出的光線能有更多的光線是直接射出不經由反光碗反射出往的。
   
     8.要求達到的外不美觀措置:必需耐磨
   
     9.要求防水機能:能防年夜雨衝淋即可。
   
     10.價位:按小我經濟實力,一般選擇中價筒就夠用了。
   
     五.送給MM用手電(MM在晚上就會想起你)
   
     1.筒子類型:怎麽花哨,怎麽惹MM喜歡為遴選筒子的第一首則。
   
     2.要求達到的亮度:亮度當然不能太差,但MM凡是要求也不會太高。
   
     3.LED的光色:用白光即可。
   
     4.用各類電池的續航時刻:這裏的繼航時刻,以你想下一次見到MM的時刻而定。好比你很想馬上再次見到MM,那麽就用好比CR2或是CR123等鬥勁難買的電池,所需要做的就是把電放光或是隻恰當的充一丁點電,很快,電筒沒電了,MM就來找你啦。假如你並不想見到該MM了,那就可以用AA電池的或是AAA電池的筒子來送她,假如用這個電池沒電了後她還來找你的話,你麻煩就年夜了。
   
     5.用什麽電路:無所謂,隻要不是很等閑壞的就行。
   
     6.電路要什麽檔位:MM並不是都很聰明,什麽分組分檔啊的東東一般不會用而且感受你煩,可是隻是一檔又不夠花哨,也不能浮現你的筒子的出格,所以必需的二檔就是高亮和爆閃,並對她說爆閃是防狼的,不管什麽狼見了城市跑失蹤的。
   
     7.用什麽光杯:亮晶晶沒塵埃的即可。
   
     8.要求達到的外不美觀措置:最好要耐磨的,好比不鏽鋼的,要否則放化妝包包裏和她的各類奧秘刀兵PK沒幾天就渙然一新,她就會想你怎麽送這麽不牢靠的東東,估量你這小我也是差不多吧。
   
     9.要求防水機能:能防年夜雨衝淋即可,可以泡在水中的表演給MM看,當然是做好把筒子送給MM的心理預備才給她看的。
   
     10.價位:按小我經濟實力,一般廣播種的沒法子,隻能選差一點的.假如是選定來當LD的,那當然選擇貴的筒子啊,越貴越好。
   
     手電筒根基常識
   
     手電的根基事理:手電由發光體、電池、電路、外殼、反光杯、電路倉、開關等組成,根基事理是電流從電池出來,然後達到電路,經由電路調整電壓和電流,然後輸出到發光體,進行點亮照明。
   
     一.發光體
   
     手電用的發光體有:白熾燈、LED和HID等,LED的亮度單元統一用流明(Lumens)標示,也就是凡是說的光通量。
   
     1、LED:
   
     最風行的就是LED了,中文全名就是“發光二極管”,小功率的LED一般都是多頭用在1AA或者3AA,這個我就不多說了,功率其實太小,家用還可以,不外戶外就差多了,首要說說戶外使用的3W以上的年夜功率吧,首要代表也是今朝最風行的是美國CREE的LED,壽命長,按照廠家數據最高可到10萬小時。
   
     首要型號的參數:
   
     P3,350mA亮度73.9-80.6Lumens,700mA亮度119.7-130.6Lumens
   
     P4,350mA亮度80.6-87.4Lumens,700mA亮度130.6-141.6Lumens
   
     Q2,350mA亮度87.4-93.9Lumens,700mA亮度141.6-152.1Lumens
   
     Q3,350mA亮度93.9-100.4Lumens,700mA亮度152.1-162.6Lumens
   
     Q4,350mA亮度100.4-107Lumens,最年夜電流1000mA
   
     Q5,350mA亮度107-114Lumens,最年夜電流1000mA(可達220-250lm)
   
     R2,最年夜電流1000mA(可達260lm)
   
     當然型號良多,我們最常用的也就是P4、Q2、Q5,其中此刻最風行的莫過於Q5了因為效率高,亮度年夜,電流可以到1A,亮度最高能到250流明。假如想遠射和泛光都好就用MC-E和P7,確實好,適合自行車和城市照明,
   
     2、鹵素燈泡。
   
     以前市場上良多,在LED還沒有風行的時辰很流行,此刻很少了
   
     3、通俗的燈泡(白熾燈)。這個就不用多說了,最具有代表性的就是常見的虎頭手電了,從小陪同我們成長,不外此刻有點趕不上時代了,不外低價位仍是有良多市場的。
   
     4、充氙氣的鎢絲氙氣燈泡。
   
     裏麵充的氙氣,亮度前進良多,偏黃的光色。特點是亮度高,可是壽命短,也就最多40小時擺布。
   
     5、HID(氙氣體高壓放電燈)。
   
     燈泡裏麵充的氙氣,高壓點亮,亮度超高,功率常見的功率有10W、24W、35W,亮度在1000-3000流明,燈泡壽命最高的能有3000小時,是手電重點佼佼者。利益是良多,錯誤謬誤:因為燈杯和安靖等身分,體積下不來,體積比一般的單節18650的手電偏年夜,最要命的就是一個字“貴”,最廉價的也要1000多,不是一般玩家消費的。
   
     二:電池
   
     手電筒常用的電池有AA(5號電池)、AAA(7號電池),AA又分堿性電池也就是凡是說的不能充電的幹電池(1.5V)和可以充電的鎳氫電池(1.2V);
   
     還有就是鋰電池了,電壓2.45-4.20V,型號有14500、16340、18650等等,良多伴侶看這些數字有些暈,說怎麽區分啊,其實很簡單,定型號的數字都是有原因的,好比14500電池的直徑是14毫米,長度是50毫米;16340電池直徑是16毫米,長度是34毫米,以此類推,18650電池就是直徑18毫米,長度65毫米。
   
     鋰電池還分帶嗬護電路的(防止過充過放的電路)和不帶的,巨匠應該都知道鋰電池是不能過充過放的,假如電池過充就是布滿電了還在充電器不拿出來還長時刻繼續充會發生漏水或者***;假如過放,就是電池用到一點電也沒有了才往充,這樣城市導致電池報廢的,此刻加裝了嗬護電路就不會有這樣的問題問題了,可是錯誤謬誤就是體積變年夜了,比不帶嗬護電路的(就是上段說的電池尺寸)要年夜一點,直徑增添1毫米擺布,長度增添2毫米擺布。使得有些手電放電池的時辰有些堅苦,需要慢慢試探的才能塞進往,不外年夜部門手電都是可以輕鬆放進往的。
   
     還有就是電池串聯並聯的問題問題,串聯電流不變,電壓為之前2倍;並聯電壓不變,電流為之前2倍。
   
     假如電池是帶嗬護電路的(帶防過充過放功能)就不用看以下介紹了,以下主若是針對沒有嗬護電路鋰電池講解的:
   
     新品電池的電量不是太多;要電池在第一次使用時,不需要充電時刻太長,僅按照充電器的充電指示措置即可:
   
     在充電時,按照充電器的充電快慢,當指示燈的顏色轉變時就當即掏出電池,不要過充,建議充電時刻不要跨越3-5小時;
   
     充完電,要把電池從充電器裏掏出;
   
     選擇充電器,最好使用有防過充的充電器;
   
     在使用時,按照電筒對電壓的要求使用電池,不要亂用,以防燒壞電筒;
   
     在使用中,當電筒的亮度發生較著轉變時就要封鎖電筒,防止過放,(不能同手機電池那樣,用到手機自動關機,這樣電池就會過放,而不能再用);
   
     AG国际馆,手電筒使用技巧:電筒在使用過程中,要保證散熱正常,用手拿著就是最好的體例,建議放著點亮時刻要按照電筒的發燒情形實時用手拿一下,以便散熱;
   
     電筒在使用時,建議每用30分鍾後封鎖2-3分鍾,以便散熱;寄望電池的防水防潮防摔等。
   
     三:電路
   
     電池可以直驅(就是直接將電池的兩頭用導線鏈接到LED的正負接頭上)年夜部門LED的,可是電流不不變,有年夜有小,等閑造成LED壽命縮短發生光衰,所以節製電壓和電流的手電筒專用電路就降生了,電路首要有下幾種:
   
     1、升壓電路。首要用於使用1AA、2AA電池的手電,因為年夜部門LED的工作電壓在3.6擺布,AA電池電壓在1.2-1.5,電壓不夠,需要將電壓升到3.6才能使LED正常工作,也就發生了這種電路。
   
     2、降壓電路。一般用在雙鋰電手電筒上的,好比用2節16340的手電筒,LED的工作電壓在3.6,而2節16340串聯的電壓有7.5V擺布,就需要把電路的輸出電壓降到3.6為LED供電。
   
     3、自動升降壓電路。顧名思義就是當電池電壓高於LED的工作電壓的時辰就把輸出電壓降到LED的工作電壓,當電池電壓低於LED工作電壓的時辰把輸出電壓升到LED的工作電壓,這樣就發生了恒壓恒流,這就是最理想的電路了。
   
     四:筒身、反光杯
   
     1、筒身。高檔手電年夜部門都是鋁合金外殼,材質都差不錯,首要區別在概況措置上,一般年夜部門手電隻要沒有非凡用途都是通俗的氧化措置,以黑色、灰色為主。有些手電要求能夠抗磨概況不失蹤色的,那就采用陽極氧化措置,措置後概況堅硬,用刀刮也不會呈現痕跡,不外價錢就高了。
   
     2、燈杯。常見的有橙麵杯和光麵杯,橙麵杯的概況是凹凸不服的橘皮狀,特點是反光平均,照射出的光斑標致;光麵杯的特點是反射效率高,聚光機能好,也就是遠射下場好,可是照射出的光斑外圈有層光環讓人感受不完美。

   The LED flashlight novice purchase necessary entry information
    
   If you need to buy a flashlight, need it, the reason must have a good flashlight, not necessarily an expensive flashlight does not necessarily a good work flashlight. Only for their own use, is the best.
    
   In order to let the not very savor the LED flashlight novice can quickly find the purpose and requirements of the flashlight, below from your procurement flashlight to write. You only need to press your request to find a large problem, you can find what you need for your cheese.
    
   General flashlight primary the following purposes:
    
   A walk lighting with a flashlight
    
   Is the most common use of a large multi-downstairs for the night on the evening only way to work or go out to bring in just the lighting to make walking in general requires a pan light with plenty of medium brightness, the color is good. Cheese do not ask for much, choose a wide scale. OUR Eve Eve are the torch can be content with such a request.
    
   1. Cheese types: with a 18650 straight or AA cheese.
    
   2. Required to achieve the brightness: flat Eve trail walk brightness less demanding enough, a power of more than 1W AA cheese. 18650 cheese if village dirt road or mountain mountain road, it is best to use statistics.
    
   3. LED light color with a white light LED, the pavement is dry on the line, be it mountain or in slippery situations, it is best with hot white or natural white LED to add color rendering, at the same time, can cheese with the power of a large point with a large power cheese, the most important fact that peace.
    
   4. Circuit to stall: a single file or high in the explosive flash third gear. The flash burst prime used to remind people to use to cross the road.
    
   5. What light cup: requirements floodlight, so recommend using orange peel cup, and preferably lighter orange face cup. The reason to use shallow reasons, is not only lighter relative condenser, the more light the LED light is directly emitted via the reflector bowls reflecting to. The benefits via reflector bowls reflection orange peel reflector less efficient, and some can only reach about 70%, it is not through the reflection will light a little. When using the power of cheese smaller case, I do not recommend using orange peel cup of the cheese, reflecting a higher rate of glossy cup cheese, of course, refers to the light a little glossy Cup.
    
   6. Required to achieve outside the unsightly processor: according to my enthusiasts.
    
   7. Requirements the waterproof functions: Anti-year night rain shower can.
    
   8. Price: economic strength, general selection of low-cost barrel suffice
    
   . EDC with the (EDC mean carry with them every day, to prepare for contingencies)
    
   1. Cheese Type: EDC the course convenient carry. Differences as required, battery and volume of cheese also divided: the most convenient AAA; 16340 is the brightest and most long-range, all aspects of functioning are good and most convenient to buy batteries AA; life moments longest straight 18650 cheese.
    
   2. Required to achieve brightness: with the point of the EDC with the bobbin and the daily usual walking bobbin there are many differences in the case reached four weeks functioning requirements must be sufficiently small in order to facilitate carrying. So I think the EDC cheese requires much higher than walking with barrel. EDC feature is in a large part of the hour by simply highlighting a few seconds or a few minutes, without considering the long time lit fever. Require high brightness natural lithium best. General requirements on AA or AAA.
    
   3. LED light color: white can.
    
   4. Various types of battery life moments: the pursuit of a highlight, with various types of lithium batteries. Depletion in LED power 3W, current 750MA, various types of lithium batteries following the flight time: 18650 endurance time in three hours; 16340 or 14500 life moment in 1 hour; 15266 or 10440 life time of 20 minutes; pursuit of medium-power but versatility, with all the small shop can buy popular battery. Rechargeable AA batteries, the discharge current 2A mercy, life time is about 1 hour; to reach a 2200MAH alkaline AA batteries with the capacity of the high-quality, discharge current 1A mercy, life moment about the nearly two hours (with 2A current uneconomical to discharge, often only highlighted more than half an hour); garbage AA batteries, 1A discharge nor economical, best 500MA current discharge, battery life time can reach about two hours.
    
   5. What circuit: 18650 cylinder is preferably 7135 composed of a constant current circuit, does not recommend using the booster circuit, the 7135 circuit constant, high efficiency, 7135 error error of the constant current circuit when the voltage is low to the inevitable level the lower, the more brightness, this error fallacy in the EDC often benefits: Who can guarantee that when you are with a flashlight when your flashlight electric just is plenty of it, when your battery is low, the 7135 circuit just be able to supply a very dark light, at least for it. AA cheese, it would only boost circuit can be used you, preferably with good quality and efficiency, to delay life time to save power.
    
   6. Circuit to stall: high, medium, low, burst flash, SOS, with most still in second gear.
    
   7. What light Cup: head diameter Eve is like straight 18650 and 16340, recommend using a lighter orange face cup. The reason to use shallow reasons, is not only lighter relative condenser, the more light the LED light is directly emitted via the reflector bowls reflecting to. The benefits via reflector bowls reflection orange peel reflector less efficient, and some can only reach about 70%, it is not through the reflection will light a little. When the case of the use of the cheese head smaller, the like AAA bobbin, recommendations Smooth cup cheese reflecting a higher rate, and good glossy cup can also be in the AAA near clustered into a spot, there is a The brightest spot is still fresh fighting.
    
   8. The requirements reach outside unsightly processor: the best wear resistance, like stainless steel or HAIII to.
    
   9. Require waterproof function: Anti-year night rain shower can
    
   10. Price: economic strength, generally choose a slightly more expensive cheese fact is followed, operating high all day, of course, starting point.
    
   Outdoor search with (hunting or outdoor activities, the need to highlight the necessary long-range)
    
   1. Cheese types: essential 18650 Eve head (the power of a large, high brightness, long-range, following the flight time from 1.5 to 3 hours); if not pan-light and do not have high brightness, do not need a good spot, you can use transferred spot pole small lens flashlight.
    
   2. Requirements to achieve the brightness: overclocking lot are LED, limit the use of LED current tends to reach 1000MA 18650 cheese, the current reaches the reach 1200MA is close to the limit of the LED Q5 add another current, luminous intensity adds a very small, but the LED life a large reduction is not recommended across 1200MA. At this time, LED depletion power reach 4.5W mercy.
    
   3. LED light color, in the case of wet circumstances, it is best to use a thermal color LED, in the case of dry, preferably with a white LED, because the white color than the heat should be bright.
    
   4. Various types of battery life moments: the pursuit of highlighting, 18650 big head, power 3W, current 750MA cheese is the minimum requirement, the life time of three hours; current 1200MA power reaches 4.5W, the Q5 LED limit , because of the boost circuit, the LED current 1200MA, the battery-side of the current may reach 1.2 to 1.7A, life time at 1.5 hours.
    
   5. What circuit: course 18650 lithium battery, but the Q5 voltage battery 3.7V discharge platform can not be sufficient a large current supply to the LED, it is generally to use booster circuit, best quality good efficiency, because of the short life time of the highlighted file and uneconomical.
    
   6. Circuit to stall: high, medium and low grades and five-speed.
    
   7. What light cup: because they require less floodlight, generally is a a deep fresh fighting a large-caliber glossy Cup.
    
   8. Required to achieve outside the unsightly processor: the general requirement cheese black.
    
   9. Requirements the waterproof functions: at least anti annual night rain shower, because sometimes wading, so the general requirements can soak in the cheese at high temperatures cold water nothing.
    
   10. Price: small, I need to achieve what kind of long-range function may be to achieve the high brightness and super-long-range function, usually in high-priced barrel if the brightness and long-range function and outside unsightly and so compromises, it can be used in low-cost cheese completely.
    
   Four-vehicle use (never on the car, useful when you can readily get the cheese)
    
   1. Cheese type: recommended straight, you can use 18650 straight (the power of a large, high brightness, following the flight time of about 3 hours), or such a large power AA cheese straight (battery everywhere can buy, carry convenience, following The flight time of about 1 hour).
    
   2. Requirements to achieve the brightness: if 18650 cheese, the current reaches 750MA LED depletion power of the 3W mercy on the line, if AA is best to use battery terminal 2A current can reach high grade point AA.
    
   3. LED light color, if sometimes want to walk with or repair with appropriate hot white fresh fighting.
    
   4. Various types of battery life time: 18650 lithium battery, the cheese life time of power 3W, current 750MA in three hours; when 2A mercy rechargeable AA batteries, the discharge current, the life time of about 1 hour; capacity to achieve quality 2200MAH alkaline AA batteries, the discharge current 1A mercy, life time around for nearly two hours.
    
   5. What circuit: 18650 cylinder is preferably 7135 composed of a constant current circuit, strongly not recommended to use the booster circuit 7135 circuit constant, high efficiency, 7135 error error of the constant current circuit when the voltage is low to the inevitable level , the more you use the brightness lower this error fallacy interests but is no power strong need flashlight. AA bobbin, the booster circuit can be used it bird, preferably with the quality is good, especially in the long time after shaking reliable high to ensure that the purpose can be used at any time.
    
   6. Circuit to stall: high, medium, low, burst flash. Explosive flash is necessary, in the car can serve as a reminder, the purpose of the car.
    
   7. What light cup: according often close, if the spot is too concentrated instead not see, so they requested that the floodlight was very good, so recommend using a lighter orange face cup. The reason to use shallow reasons, is not only lighter relative condenser, the more light the LED light is directly emitted via the reflector bowls reflecting to.
    
   8. Requirements to achieve outside the unsightly processor: Required wearable
    
   9. Requirements the waterproof functions: Anti-year night rain shower can.
    
   10. Price: economic strength, general choice in the price of barrel is enough.
    
   MM gave with a flashlight (MM in the evening will think of you)
    
   1. Cheese types: how fancy, how to mess with MM like the first song is for the selection of the cheese.
    
   2. Required to achieve brightness: brightness is certainly not bad, but MM All requirements are not too high.
    
   3. LED light color: white can.
    
   4. Moment with the various types of battery life: here following the flight time, you think the next time I saw the moment of MM. Like you would like to once again met MM like CR2 or CR123 batteries not buy fresh fighting, then need to do is to electric shine or does it only appropriate to charge a little bit of electricity, and soon, the torch is not electricity, MM will come to you. If you do not want to see the MM, it can use AA batteries or AAA batteries cheese to send her, she did not use the battery power to come to you, you trouble on Eve.
    
   5. What circuit: does not matter, as long as it is not a very lightly bad line.
    
   6. Circuit to what stalls: MM is not very clever, split into groups to file stuff do not generally use and feel you trouble, but just enough fancy a file can not emerge the cheese out of line, so necessary second gear is highlighting and explosive flash, and she said, the explosive flash coyotes, no matter what the wolf met with city ran disappearance.
    
   7. What light Cup: shiny can not dust.
    
   8. Cosmetic Bag bag and her all kinds of mysteries sword outside unsightly processor required to achieve: the best wear resistance, like stainless steel, otherwise put PK did a few days to a contemporary new look, she will want you how to send so insecure stuff, measure your ego is almost right.
    
   9. Require waterproof function: night rain shower can can prevent years, you can soak in water show to the MM look, of course, is to do a good job gave the cheese MM psychologically prepared for her to see.
    
   10. Price: economic strength, the the general broadcasting kinds can not be helped, can only choose almost of if it is selected when the LD, and that, of course, choose your cheese, the more expensive the better.
    
   Flashlight foundation of common sense
    
   Flashlight foundation affair: flashlight foundations affair out by the current from the battery, and then reaches the circuit, via the circuit to adjust the voltage and current, and then output to the light emitting body by the luminous body, the battery, the circuit, the housing, reflector cup, circuit positions, switches, etc. lighting lighting.
    
   A luminous body
    
   Flashlight with luminous body: incandescent, LED and HID, LED brightness units unified with Lumen (Lumens) mark, that is, those who say that the luminous flux.
    
   1, LED:
    
   Most popular LED full Chinese name is "light-emitting diode, small power LED are generally bulls used in 1AA or 3AA, I do not say this, in fact, too small power, can also be home, but outdoors much weaker, first and foremost to talk about more of a large power 3W outdoor use, the primary representatives present the most popular in the U.S. CREE LED, long life up to 100,000 hours, according to the manufacturer's data.
    
   Primary model parameters:
    
   P3, 350mA brightness 73.9-80.6Lumens, 700mA brightness 119.7-130.6Lumens
    
   P4, 350mA brightness 80.6-87.4Lumens 700mA Brightness 130.6 141.6Lumens
    
   Q2, 350mA brightness 87.4-93.9Lumens, 700mA brightness 141.6-152.1Lumens
    
   The Q3, 350mA brightness 93.9 100.4Lumens, 700mA brightness 152.1-162.6Lumens
    
   Q4, 350mA brightness the 100.4-107Lumens, most Eve current 1000mA
    
   Q5, 350mA brightness 107-114Lumens, the most Eve currents 1000mA (up to 220-250lm)
    
   R2, the most Nianye current 1000mA (up to 260lm)
    
   Of course, made a lot of models, we are the most commonly used is P4, Q2, Q5, of which the most popular at the moment than the Q5 a high efficiency, brightness, a large current to 1A, brightness up to 250 lumens. If she wants a long-range floodlight with MC-E and P7, really good, for bicycles and urban lighting
    
   2, halogen bulbs.
    
   A lot on the market, not yet popular in the LED hour is very popular at the moment, few
    
   3, popular bulbs (incandescent). Needless to say this, the most representative is common the Steller flashlight childhood accompanied our growth, nothing more than a bit behind the times at the moment, nothing more than low-cost is still a lot of market.
    
   4, rechargeable xenon xenon bulb tungsten filament.
    
   The xenon filling inside, brightness forward a lot, the yellowish color of the light. Characterized by high brightness, but life is short, and it was up to 40 hours at the mercy.
    
   5, HID (xenon gas high-pressure discharge lamp).
    
   Xenon lamp inside the charge, high-voltage lighting, ultrahigh brightness, power of common power of 10W, 24W, 35W, 1000-3000 lumens brightness maximum lamp life 3000 hours, flashlight focus leader. Interests a lot of errors fallacy: because the lights cups and Anjing identity, volume, get down, the 18650 volume than the average single flashlight partial Eve, is the most terrible word "expensive", but also the cheapest over 1000 not players spending.
    
   : Battery
    
   Flashlight battery AA (batteries), AAA (7 battery) AA was divided alkaline batteries is who can not charge the dry batteries (1.5V) and can charge the nickel metal hydride battery (1.2V);
    
   There is a lithium battery voltage of 2.45-4.20V models 14500,16340,18650, many of my friends to see these figures is somewhat confusing, to say how to distinguish ah, in fact, very simple, specific model numbers are reason , like 14,500 diameter of the battery is 14 mm, the length is 50 mm; 16340 batteries is 16 mm in diameter, and is 34 mm in length, and so on, the 18650 battery is diameter 18 mm, length 65 mm.
    
   The lithium battery zoning care circuit (to prevent overcharge and over discharge circuit) without masters should know that lithium batteries can not overcharge and over-discharge of the If the battery charge is full power also charger not come to also long time continue to charge occurs leaking or ***; if over-discharge, the battery used electricity only to charge, so that the city lead battery scrap, at the moment the installation of a care circuit would not be such problem, but error fallacy is the volume of a large, than without care circuit (that is, on said battery size) to Eve that an additional 1 millimeter in diameter mercy, the mercy of an additional two millimeters in length. Hour battery makes some flashlight put some hard, you need to slowly tempted to stuffed to nothing more than a large department flashlight can be easily put to.
    
   There is the problem of the batteries in series parallel series current constant voltage of 2 times before; parallel voltage constant current 2 times before.
    
   If the battery with care circuit (with anti-overcharge and over-discharge) without looking at the following describes the following main explain not care circuit lithium battery:
    
   New battery power is not too much; battery first use, do not need charging time is too long, you can only renew in accordance with the charger charging indicator:
    
   Charging, the charger the charging speed of, when the indicator color change immediately took out the battery, not too filling, not to recommend charging time span 3-5 hours;
    
   Fully charged, the battery should be pulled out from the charger;
    
   Select the charger, it is best to use a charger with anti-overcharge;
    
   Use, in accordance with the torch using the battery voltage requirements, and should not be used indiscriminately, to prevent burn torch;
    
   Blockade flashlight in use, when the brightness of the flashlight obvious shift is necessary, to prevent over-discharge, (not the same mobiles phones battery, used the phones automatically shut down, so that the battery will over-discharge, and can not be reused);
    
   Tips: torch during use, to ensure normal cooling your hands is the best style, recommend lying lit moment to put his hand in real time in accordance with the torch of fever situation, in order to heat;
    
   The torch when in use, it is recommended that each blocked after 30 minutes for 2-3 minutes, so that the heat; hopes battery waterproof moisture resistance and other.
    
   3: Circuit
    
   Battery can drive straight (is directly to the battery two wire link to the positive and negative connector on the LED) LED's Eve departments, but the current is not the same, there is a large and a small, lightly cause shorten the LED life light failure occurs, so temperance flashlight circuit voltage and current on the birth of the the circuit primary next several:
    
   1, the booster circuit. Mainly for use 1AA, 2AA battery flashlight, because the mercy of a large department operating voltage of the LED at 3.6 AA battery voltage 1.2-1.5, the voltage is not enough, you need the voltage to rise to 3.6 in order to make the LED work properly, it happened this circuit.
    
   2, antihypertensive circuit. Generally used in dual lithium flashlight on, like 2 16340 flashlight, LED operating voltage of 3.6 2 16340 series voltage 7.5V mercy, we need to reduce the output voltage of the circuit to 3.6 for LED power supply .
    
   3 automatic buck circuit. The name suggests is that when the battery voltage is higher than the operating voltage of the LED the hour put output voltage drops below the operating voltage of the LED, LED operating voltage when the battery voltage is less than an hour to the operating voltage of the LED output voltage to rise, this took place constant pressure constant current, which is the ideal circuit.
    
   : Flashlight, reflective Cup
    
   1 Tongshen. Upscale the flashlight a large departments are aluminum alloy shell materials are poor good primary distinction in the overview renew, generally a large department flashlight the extraordinary uses are popular oxidation renew, mainly black, gray. Some flashlight requires the ability to color antiwear Facts not missing, then anodized renew, renew, after OVERVIEW hard not rendered with Daogua traces, but the price is high.
    
   2, light cup. Orange peel-like the common orange surface cup and glossy cup orange surface, cups overview bump refuses to accept, is characterized by a reflective average, the irradiation spot Peugeot; glossy Cup characterized by reflection high efficiency condensing function, but also is the long-range fate, but irradiation spot outer layer aura of people feel is not perfect.
