I've got some 15w 4.8v mr11 bulbs. Anyone got a data sheet on this bad body as far as lumens, amp draw, lifespan, and overvoltage potential goes?

I'm going to order some Willie Hunt regulators and am trying to decide on what voltage to specify. I've got afeeling these babies will take a LOT more that 10% overvoltage.

I've been running them (some) at 6.2v, which is about 30% over the 4.8v.
