Has anyone had much to do with high power LED'S and the optics.
I am going to make a motorbike head lamp (smiler to the one out of green hornet)
It is going to have 2 rows of 3 LED i want one side as high beam one side as low
Need to know what LED'S,power supply and optics need (would like square optics if i can)
and last how much heat is produced from the high powered LED'S
