KL3 powered by the B65 NiCad - Runtime test.

[Size15's]

Runtime test complete:

The KL3 powered by the B65 NiCad Battery Stick gave me a constant-on constant-output ["co-co"]runtime of 110 minutes.
This is based on one single B65 (DE30 337030 [old Sure.Fire "Laser scatter" logo]) taken fresh from my green-lit C200 charger.
I compared it to my E2e+KL1 running two slightly used SF123As constant-on.

After about 110 minutes, I noted that the KL3 output 'suddenly' dropped below the KL1 and lost it's edge. When I put the KL3 on a two SF123A SureFire, it clearly beat the E2e+KL1 with the KL3 having a white intense central beam.

Therefore I consider the regulated output to have finished. No doubt there is more output left in the B65 but I don't consider it worth the risk of harming my only B65 in order to check out the "moon" mode.

Regards,

Al

Al:

The KL3 thus appears to work well on the 4 cell 4.8V B65. How does it perform on 3.6 V? I could put 2@ 2000 mAh 43mm long 4/5 A NiMH cells plus a 50 mm long A NiMH cell totaling 136 mm into a 9P body with an A19. 136 mm also happens to be the combined length of 4 CR123 cells. I imagine these 3 cells carry more useable watt hours than the B65. This configuration would be attractive to me if the KL3 which is promoted for 6 to 9 V use could function on 3.6 V.

Thanks for the run time test Al. Almost 2 hours isn't bad at all. Now I am sorry I lost out on the used KR2 kit.

Al,
Saw your post in the other thread about starting this one. Any comments, or another thread about the E2E w/KL1 (especially comparison with the standard MN03 in terms of output and throw) would be much appreciated.
Thanks.

When I recall that 1st graph showing the KL3 w/ 3 cells...I keep thinking of all those flat lux hours...ohhhhhhhh baby.

I currently have a 6P/R along with the B65 NiCad battery. I would like to buy the KL3 to use with this setup but are there any risks involved? I know that B65's have a lot of juice fresh off the charger. Will it kill the life expectancy of the KL3 or will the KL3 damage the B65? TIA.

ET - the KL3 is designed to work from 6 to 9 V - 2 or 3 123 cells - no matter how you charge that B65 stick it won´t have anywhere near the voltage of 3 123 cells - you are save - no worries.

Oh right, I forgot you could use it in the 9v lights. So I'm safe. Time to order. Thanks Klaus.
