Okay, so your not using the true wireless setup? Induction lights were actually created to be cordless, the ballasts are the transmitters which typically operate anywhere above 1.2ghz and the magnetic drivers are the receivers - The heat issue I was talking about is much like your phone heating up when your on a long conversation, the receivers are notorious for discharging excess energy into heat... I'm an engineer, but Tesla was a born genius.

Anyway, what kind of temps do they put off?
