Hi guys,
I am planing to repair a dive torch wich I had previously modified to a 3Xml drop-in. After a while in usage the driver burnt (my fault, I used it outsider the water and it overheated).
Anyways, I was thinking to use a simple resistor instead of a led driver, so I would also be able to use the step less dimmable funktion off the torch.
The battery pack is a 11cell 1,2v NiMh and the 3Xmls are in series (planing to drive them at 3.3v and around 2A )
(Vf - Vs) / Amp = Ohm
9.9v-13.2v = 3.3v/2A = 1,65Ohm
So I would like to ask you if I can use a 1.5-1.7Ohm 20-30watt capable resistor for this repair.
I hope you guys can understand it
Thanks a lot
Mark
