Was sponsored this light, they were going to give me a larger light on the second run for them but never delivered, and ended up having to use this for veg then supplement with not one but two Mars lights to get thru veg. Might use this in my small veg tent for a mother and maybe some autos, decent Samsung diodes and Osram reds and a lot of light for a little guy. Might end up selling it tho. It's designed for a 3x3 which was why I needed them to send one for 4x4, but I imagine if used as designed in the size tent it's probably pretty good, though v low on red light.
