To get even more brightness, rather than combine LED's into one flashlight, multiple LED's could be mounted to the same chip. These multi-die LED's produce 400 to 900 lumens. The Luxeon V was one of the first and produced 100-140 lumens. Seoul produces the P7 and Cree produces the MC-E, each with 4 LED's on a chip. | To get even more brightness, rather than combine LED's into one flashlight, multiple LED's could be mounted to the same chip.

Cree responded with the XM-L which has a larger (than the XR-E/XP-E series of LEDs) single die and can be driven up to 3 amps. | ||
