吕兄威武！
我一般用单锂电，所以不用考虑2XCR123A了，等以后有好电路，LED再上一个台阶的时候再作打算吧
换了XML后还能1XCR123A驱动吗？帮我试试看吧
原来的LS 5W的电路根据LUX V的VF，可以1XCR123A驱动的
KL5随缘吧，其实我很期待KL5的效果，就可以省去买FURY那个丑八怪了

楼主家里必藏有拆货神器！！
晚上我公布，拆火神器！
关注老KL5中
论坛大力王啊！以后可以开个小店，专门拧头子。{:1_297:}

ls 5w 版本的KL4电路性能测试如下
1X123A驱动没问题 用满电单节CR123A电池 测试 电池端电流 约600ma。
将此电路焊接xml，用实验电源 测试结果如下：
此电路最低工作电压 2.32V
2.32V - 2.6v工作电流 350ma-400ma
2.7- 2.8v 工作电流500-750ma
2.9V-3.6v 电路在此范围内进入恒功率状态，电池端电流随电压升高 而降低。2.9V 880ma3.6v 665ma
3.7V开始横流失效
3.7V 750ma
3.8V 880ma
3.9V 920ma
4.0v 1040ma
4.1V 1160ma
4.2v 1250ma
4.3v 1350ma
4.4v 1500ma
4.5v 1620ma
4.7v 1850ma
4.8v 1960ma
4.9v 2080ma
5.0v 2200ma
更高电压没有测试。
新版的KL4头续航 怎么样？

测一下空载的输出电压看看，这个应该是7V左右输出。。。
楼主威武啊

老谢害人，刚刚测试下我那个老版电路空载，电压神速升高，好没来的及看，电路就冒烟烧毁。看来这个电路是不可空载的。

现在可以得出结论了，老版电路是判断电流的，电流不够就往上升压。一直升到电池撑不住，我用的实验电源，电流供应充足，所以一下不知升了多高，直接冒烟了。回头我找找零件，看看能否修复。

如此看来2XCR123A是可以用的
当时测电流的时候就是1x17670的电流比2X123A的大，这个电路是横功率的
不是，如果用xml，电压超过3.7v就不是横功率了

If the KL4 head is the old version that uses a Luxeon V LED, then the driver is a boost driver that was designed to boost 2x123A (at roughly 5V) to power a ~6.5V LED. If you use a Seoul P7 with Vf of around 3.0V at the boost driver's drive current of around 650mA, your Vbatt > Vload and you'll be in direct drive. Whether or not the boost driver will like this depends on how hard you run the LED in direct drive and how robust the driver is. For 1xLi-ion at a nominal voltage of 3.7V, a P7 could draw over 2A drive current. I know that folks on CPF have done this mod and have claimed that it works, but my opinion is that it is unwise and the numbers don't bode well for product reliability/longevity.
You will face the same issue with an XM-L swap in an old version KL4. In fact, it'll most likely be worse than for a P7. At 3.7V Vf, an XM-L will draw well over 3A. You risk cooking the LED and the boost driver.
For the old version KL4 that uses a Lux V, the standard LED swap is with a Cree MC-E wired in 2S2P. That is electrically compatible with the stock SureFire boost driver.
Now if your KL4 is the new version that uses a Seoul P4, then a direct swap to a P7 or XM-L should work fine, at least in terms of driver compatibility. You'll probably have to drill out the reflector opening to fit the larger diameter P7. You may also have to change how you solder the P7's leads to the KL4 since the P7 is much larger in diameter than a P4. For the XM-L, you may have to shim it to the proper focus height, depending on what MCPCB the XM-L is on.
