Like i said, I'm hesitant but am in the process of doing my due diligence. would you say they yielded no improvement over the halogens or produced less usable light?
They produce about 2/3 the light output of an HID bulb, but only in one or maybe two (if you're lucky) directions.
Also anything with active cooling is bound to fail. You need something with passive cooling like a big aluminum heat sink.
In a projector, the lower LED is useless anyway, as is the unidirectional LED chip, so we made a triple layout LED bulb:
It also has a copper core in the center to help get the heat away from the chips and out the back:
