DD light engine - updated with pictures!
Sorry if this is a dumb question, but has anyone has done a direct drive light engine?
I was playing today with an UX1L star in my bench and got about:
800mA on a charged 4.2V RC123 cell
790mA on a charged 4.2V PILA168S cell
820mA on a charged 4.2V bare 16750 cell
940mA on a charged 4.2V bare 18650 2400mAH cell
With these numbers, who needs a regulator? /ubbthreads/images/graemlins/wink.gif
So seriously, besides the obvious drop with time due to no regulation, has anyone done this? I must say I am really tempted /ubbthreads/images/graemlins/evilgrin07.gif
