This driver will power either a single or 2 serial wired Cree XM-L at 2.5 amps. This is the maximum safe level in my opinion, read the Cree data sheet re "Thermal Characteristics"
2 serial wired XM-L T6 will output 1600 lumens at 2.5 amps, and this baby will do it.
Soldering and build quality extremely good.
Size matters as they say, and considering the electonics it could be a lot smaller. Its dimensions could present problems, and considering a lot of it is doing nothing, that is a real pain.
All of these components can vary in spec, check that the loop back resistors are 0.1 ohm and 0.4 ohms, working inward from the outside
