Surefire KL5A: No more 9V?

SlightlyDim · Aug 22, 2008

Anyone know whether the Surefire KL5A head works properly on 3 cells?

The original Surefire KL5A page had:

6P, 9P, C2, C3, G2, G2Z, M2, Z2, Z3

as the supported lights, now shows:

6P, C2, G2, G2Z, M2, Z2

Has there been a new revision?

I've had one on order for a while - hoping to use it on more than 6V
(for example up to 8.4V - only used on genuine SureFire batteries, honest....)

I think the 9V-limit refers to the old version. It was a boost-cicuit (Vf ~ 6.5V) and '9V compatibility' was always questionable, at least for me. The new one should be a buck-circuit, and everything above 4V should work.

Luckily enough I just received my L5 with KL5a led assembly. I just popped it into my D3 body and it worked. I was scared at first but for CPF I though I'd give it a try. It works perfectly. There are no signs of overloading the circuits or slight blinking of the beam. :party:

Thanks. Every once in a while someone needs to take one for the team and find out if something will run on 9v.

Good to know, thanks.

I'll risk it when it turns up, was just a bit confused as to why SureFire had taken the 3 cell models off the KL5A product page.

Yeah, does seem strange. Must be a glitch, at least for now.

I ran several sets of batteries (3xCR123) through mine and all is well.

If you look at SF's "Specifications Chart", the KL5A still shows as an accesory/replacement LED head for the C3...hmmm...maybe SF is erring on the side of caution???
