LED Circuit Boards

[allburger]

Does anyone know where I can find a multi mode circuit board that will accept at least 8.4v for 2 18650 batteries that is in the US.

I ordered one from DX and its on back order and that drives me nuts.

I dont want one that cost a ton either. Under 10 dollars would be nice

Do you want buck or boost? How many LEDs do you want to drive? (I presume you want to drive LEDs.)

Do you know about the driver list?

Might have luck looking for inexpensive drivers at these places.

I am going to run a single ssc p4 off of 2 18650 batteries. As you all know that will be 8.4v hot off the charger. I believe that the forward voltage of the ssc p4 is 3.6v. I am not entirely sure what I need I guess.

Any help would be appreciated.

I do not know the difference between buck and boost.

Because you want to step down from (as much as) 8.4V to just 3.6V to drive the LED you want a buck regulator. A boost regulator increases the voltage, for example if you were wanting to run an LED from one or two NiMH cells.

I have been searching for the same myself. Other than the 2 at deal extreme, you could consider the KENNAN from kaidomain.

For more expensive options, you can use a SOB from the sandwich shoppe or a Fatman from taskled.

I am not sure about the CC5W but it appears it would work also. I wish there were more cheap options out there. I have both sku 7425 and 3256 on back order from DX myself.

I have used a couple of These in 2xcr123 lights, one being an old Nuwai that I stuffed a sscp4 in and they turned out alright. It really did nice in a Q5 module. The Nuwai did not turn out freaky bright but it was much brighter than the Lux III it did have, and the SSCP4 + textured reflector makes for a pretty ethereal beam pattern. I got mine from DX but considering the wait times getting them from SB in a matter of days might be worth the premium.


I am no mod master by any means and am just hacking merrily along...so YMMV.
