That ain't my video, I was just pointing out that dudes light is a Blackstar. And by the looks of it, it is the same one I have. The 500 watt one has 6 or 8 fans, his looks like 3 fans, so it's either the 240, or the 180.
They do have a "500" watt model (operates @ 304 watts), and it does not use 12 watt diodes, but instead uses 3 watt diodes, powered @ apx 1.8 watts each.
