apologise if this is slightly off topic, but can you use 2xR123s in the L4? Or will the voltage be too high?
the KL4 head wasn't designed for voltage higher than 6v... Thats one of the reasons I got a E2L since it can handle up to 9v... that way i can safely use TWO 3.6~4.2v rechargeable li-ion batteries... it works GREAT! it may even be a little brighter than normal 123's...
i use the diffusion head with my E2L and it makes an amazing spill... EASILY bright enough to illuminate a path when walking yet somehow not too bright when using it up close to read something for long periods of time... i bet its due to its 'softness' the diffusion head produces... the runtime on the KL1 head is a lot better than the KL4 and is regulated better... I have an E1e body so if i need a headlamp or something its easy to convert.
then if you need throw just pop the diffusion head off and you can easily illuminate long distant targets... for me that it why i didn't purchase a L4... its spill/flood is softer and more consistant... and maybe only slightly dimmer to my eyes in overall output... yet the throw of the E2L/KL1 head is almost 4x as far as the L4/KL4 according to flashlight reviews and my observations...
