While they don't say this in the video, the Cree XHP70 chips they used are rated at 32w each with a lumen output of 4,022 per chip (equivalent to a new 100w MV lamp), and this whole thing uses 300 of them. Assuming that they are running at full power, they would be consuming at least 9,600w with a light output of 1,206,600 lumens, which is more than what 10 1,000w metal halide lamps would produce. The fact that it's able to melt through glass as shown by the radiometer test is pretty terrifying.
