Super bright, great white tint, much easier to focus then P7.
Leads of emitter not all soldered together on receipt, but very easy to fix.
Thermal management definitely an issue. Must make sure that whatever you put this in is well heatsinked. My first one melted an acrylic collimator lens after 20-40 minutes and the dome came off the emitter from the heat.
Use a good ceramic or metal thermal compound, not silicone. Power consumption is not as great as the manufacturer states. My MC-E and P7 emitters only pull 1.4A direct driven from a single 18650. Fancy 2.8A regulators are not necessary. The good news is you get ~2hrs runtime of a single 18650.
Probably the best upgrade you can give to any CREE torch that can handle the heat and power consumption.
