I am wanting to build a light with 3 XP-G LEDs wired in series. I am want to run the light off of a single 18650, What would be the best single mode driver to run this so that each LED is powered at 1000mA or close to it? I would also like to have the driver no larger than 17mm but since my light host has not been built I can change it to fit something a little larger if I have to.
Also please help me understand how this works to makes things easier for me in the future:
If I understand this correctly each LED has a forward voltage of 3.3 at 1000mA. When wired in series I would need to have a Vout of 9.9V at 1000mA. So to run a 18650 (4.2V fully charged) I would need to have a boost circuit driver... correct?
Thanks for any help you can give this light building newbie!!!
