It’s not an actual light, It’s technically just a printed circuit board with a bunch of leds on it. The end user has to configure the board(s) into a mountable fixture and wire a suitable led driver to make it a complete light. Maybe you’ve seen some of the other lights from horticulture lighting group? The qb 132 is one of their offerings, they just don’t have it in a complete fixture. It seems like it was one of their later releases, as an offering for DIY cob builders to use with their cob based drivers.
Great question! I get asked about lights several times a day, but rarely that. I like to make sure any specific light will hit a good intensity window for the space, usually around a ppfd average of 700-800 umols per second. There are plenty of reasons to go a little more or less, but I feel like if a user can get to intensity around there everything else kinda becomes less important. After that it becomes pretty much weighing the other options against each other. Stuff like cost, light spectrum, warranty, dimming features, or a lot of times it’s even availability. Each of those features mean something a little different to each individual, and without a big budget usually require a little give and take.
