Cree's own XP-G emiters already put out 132 lumens/watt. What needs to happen is price to come down on LED products. A triple XP-G star sells for around $22 each, and needs a driver that can cost almost as much. Once prices go down, and color gets better fidelity, then LEDs will take off. That triple XP-G star can put out 1000 lumens at 9.9W, and there are other LED products like Luminus Devices' SST-90 that puts out over 2000 lumens from a single emiter... oh yeah, heat is another issue, a BIG issue to be addressed.
