LED Lamps / MR16

LED bulbs in the standard low voltage MR16 style with the GU5.3 fitting.
Conventionally shaped bulbs fit a standard halogen lampholder. All bulbs will work on 12V AC but the transformer usually has to be replaced by one operating down to zero Watts because of the low power of LED bulbs. Some also work off 12V DC. The colour changing bulbs are more stable when operated from DC.
