SF L1 Cree head and SF E2 body with 17670 battery good or bad?

[marinemaster]

I have a SF L1 Cree and a E2 body that takes a 17670. Is it ok put the SF L1 Cree head on the E2 with 17670 battery? Will that be a problem? Too much voltage for the L1 Cree head? I know it will be 1 stage but that is ok. It will be brighter. Has anyone tried this combo? Is there a long term damage to the L1 Cree LED? Advice needed.

Thanks much for the input.

The L1 head is "dumb" (no regulator) and shouldn't be used on other flashlights.

Somebody did this once, I can't remember who......................

I don't think it ended well - unless you count SF fixing it for them as a positive ending.
I think of that as being back to square one but if my dead light was brought back to life by SF I guess I would feel pretty positive about it.

I have been doing this for well over a year with ML1 SSC & Luxeon heads.
I have one old L1 body bored & stroked (driver removed) by Milkyspit to fit a 17500 and it runs the head DD - except on low of course.
I have another ML1 that is running DD off an RCR123 in an E1 body with a McE2S switch. - a mini L1. Direct Drive, 150 Lumens.
I have run my SSC & Luxeon ML1's off an 18650 in a Modamag E-series body. 17650, 17500, 16340... I've run em all.

But don't do it. It might shorten the LED life. Or let out the magic smoke.

I measured it only gets around 750mA off a RCR123, so it is not super overdriving it. A 17650 will give it more juice, I should measure that and an 18650.

Somebody ran one off two CR123 for a while. SIX Volts! That's nearly double what it needs. I think that one cooked eventually.
