Correct me if I'm wrong, but this is not an LED light source. It is a Xenon or HID light that generates a ton of heat and needs a ballast that also generates heat. The heat sink arrangement they use probably works to diffuse the heat, but this is not the same as an LED solution that would run completely cool. I believe the new BMW OEM halos are LED. The aftermarket should be quick to adopt this. Come on guys, I'm waiting! At less than $100, these will blow out!
