I tried LED bulbs. Did not work.
Low setting: they would not turn on.
Med setting: They would flicker
High setting: They would turn on....reluctantly.
Guessing it has to do with the voltage levels across the bulbs. LEDs need a certain level to just turn on, whereas Halogens can handle a super low voltage.
But, yes.. I really do not like the heat (and the yellow light) the halogens generate. They tend to yellow the white finish eventually.
I am still looking into it, but it does not look hopefully about switching over to LED.
