[ 讨 论 ] SF-L1 也上了3W LED了。呵呵。。。

<P><B>L1 LumaMax</B>
Constructed of aerospace grade aluminum with a rugged military specification hard-anodized finish, and powered by a single lithium battery (10-year shelf life), the <FONT color=#ff0033>L1 LumaMax features a 3-watt LED (Light Emitting Diode)</FONT> and the extended runtime typical of LED flashlights. The L1抯 digitally controlled two-stage switch allows the user to choose either a low-output beam for close-up work or a high-output beam for full power applications -- simply depress the tailcap switch halfway for the low beam, continue depressing to activate the high beam. Twist the tailcap to achieve constant light on either beam setting. The L1 also features digital current regulation circuitry to match the LED\'s current requirements with the battery\'s output to maintain a more consistent level of light output for the useable life of the batteries (as opposed to unregulated lights, which are subject to a steady decline in light intensity beginning shortly after activation). </P>
<P>The L1 produces useable light for up to 50 hours on the low-beam setting; high-beam runtime is approximately two hours. Unlike most LED flashlight manufacturers -- who inflate the light output and usable runtimes of their LEDs -- SureFire provides realistic output and runtime specifications based on scientifically obtained measurements. Although any LED -- including those produced by SureFire -- can continue to produce negligible light output for over 50 hours, the amount of "useful" light produced is of a shorter duration. </P>

<P>不过驱动功率肯定没有3W</P>

CRCR 发表于 2005-1-31 19:27

<P>这个现在还不清楚，我想SF不会使用超频电路的吧！</P>

看来Luxeon真的是在用Lux3替代Lux1了，简化产品线。

对，这种方便，不过看手电说明是不错！尤其是LED的！

hifipenny 发表于 2005-1-31 21:50

晕，各位大大，大半年以前，L1就采用LUX 3了

大师1979 发表于 2005-2-1 01:57

3W实在不够用.L2要是短点就没了L1的销路.

funder 发表于 2005-2-1 02:29

<P>SF没有发挥3W聚光射程方面相对5W优势，可能也是为了5W的销路着想。</P>

大师1979 发表于 2005-2-1 02:37

还有人买回去改没有啊.

funder 发表于 2005-2-1 05:12

<P>当然有了，我就刚买了一个回来改</P><P>原装只有30流明，改装以后可以提到80或者120流明，聚光也能好不少，电池容量可以则增加一倍多</P>

<P>这次等我看过再转吧.</P>

<P>不会吧？Funder,电池容量如何提高1倍？难道你延长了桶身？亮度80到120流明也不会吧？LED能做到吗？</P>

原来的筒身带电路，长度刚好是2个123A，但使用1个123A，改了之后，取消电路，变成2个123A的空间，这样不是提高一倍是什么呢，呵呵：）

L1可以用一节16340驱动吗？
