The supernova lights appear to be very simple, 3 leds and some resistors. Although I've never been able to verify this from the pictures I've found online.
I'm not sure that the supernova headlight is really guaranteed to put out less than 6v, but assuming it is and a 2v Vf on the LEDs, the website is calling for no more than 1/2 watt across the tail light LED. The supernova tail light has no heat sinking, but I'm not sure how much current it draws at 6 v. The LED at the website in the OP actually has a certain amount of heatsink built in. Granted, it wouldn't work for a headlight, but it would almost certainly work in this application.
Awesome! I feel like you're picking up what I'm putting down.
That said, uhh... would that LED znomit posted work, or does that one demand too much power? Would there be a better option? Or is that a good one?
I'm really new to DIY lighting and I'm more confused now than when I started.
If I need to fit some sort of heatsink in the reflector shell of the
PDW Fenderbot I'm certain I can figure that out. I don't need the light to be
super powerful, though. Just a happy lil' taillight.
Thanks for the help so far, everyone!
