Compared to them, this LED has a more complete spectrum. The fact that it is closer to daylight. Same power draw, but WAY more light! HOW BRIGHT THIS LIGHT WAS. The entire room light up like I was using one of those lights you see in parking lots of grand openings lol.You don't need this light 12 above your plants. It doesnt matter if you keep it 12" above your plants, or 30" above. LED has an even light distribution at 24 inches.
The solid aluminum heat sink the LED's are mounted on, and no fans. But if you can get a cheap clip on fan, just aim it over the ballast on the light. It will not even get warm. The no fan is not an issue.Uses Samsung diodes and Mean Well drivers which are both leaders in LED hardware so reliability should be high. The aluminum board is thick and sturdy. It gets hot to the touch, but its much cooler than other techs. Rubbery coating reduces risk from splashes. 1xa dimmer switch;1xled quantum board ;1xhanging kit with carabiner.
