PS. The MR16 bulbs I'm using have a little circuit board that I'm assuming has at least a rectifier on it because leds have to have DC current. So the bulb itself is taking the AC of the hub and converting it to DC. I dismantled one and disconnected the circuit board and wired just the leds up to the hub with my own bridge rectifier and the leds lit up. The bulbs just don't want to accept DC because it has the rectifier already built in i guess?
