Very helpful
I have been on the hunt for a good LED homebrew system and you MTB system was one of the most straightfoward ones I have come across.
I would like to build a 300 Lumen system based on the Cree emitters so I was wondering how you build is going. Since it's winter here it's high on my list, but since your days are getting longer I imagine it is not on yours. Anyway, could I just modify your MTB schmatic and use Cree emitters with a regulator that allows either a 350 or 700 mA current?
Thanks either way.
