Very happy with this light, but I'm going to grow one plant at-a-time going-forward (that's all I need). I experimented with lux meter and lighting distance. Even though it doesn't give high light readings at 20" from the plant, I've decided that's a good minimum distance to avoid light stress. I had lots of problems with light stress because I started with 20 hr lights on. Going-forward, I'll stick to 18 hours of light (autos). This light is very-powerful for a single plant, but totally-adequate. I call this the perfect light for 1-4 well-trained plants, or one untrained plant.
