First off, I haven't had luck finding anything in my searches about this, so forgive me if it's been asked.
I was given an old G2 that wasn't working anymore. So I fiddled with it, and found that the problem was an aging fan, and burnt out LEDs. So I refurbished it by replacing the fan with a 120mm computer fan, 1 of the drivers, and replacing almost all the 3W LEDs-so so far I have spent roughly $45 on a 160W LED in a custom spectrum.
My next projects for it are 1) new(any) optics, and 2) making it dimmable by PWM from an Arduino. Optics are easy enough. Here's my problem on the dimmable thing though: I can't seem to find dimmable drivers that power a string of 1) 18, 3W LEDs, 2) 14, 3W LEDs, and 3) 2, 30W LEDs-especially in a budget I can justify for it. So I'm fishing for ideas and resources to do this dimmable retrofit.
