I've tried replacing the halogen bulbs with Lamsky G6.35 LEDs but they flicker heavily on 12v AC. I turned on halogen, no flicker. Lamsky's lamps are probably suitable for 12 DV. UPDATE: After talking to Lamsky, I found the following. Apparently they draw so little current that my power supply causes flickering because I only have one lightbulb. If you have a bunch of lightbulbs powered by the same power source, they will likely work for you.
