It went together fine, seems sturdy, and the light has good coverage/brightness. For now, I'm trying to see if it can resurrect a mostly dead plant that was light deprived, but I plan to use this more when I go on vacation along with an auto-watering system I own. My only real complaint is I don't really understand how the timer works. There are 3 LEDs labelled 4H, 8H, and 12H. The timer bottom toggles between each of these, but also has a mode where none are lit. I'm guessing 'none' means to stay on 24 hours a day? I'm guessing if I choose something like 8H, that it means it is going to go on 8 hours every 24 hours? All the instructions say is the following, which to me, just makes everything even more confusing... In ONE 24 hour cycle each color has a different time cycle. * the Red light stays on for 4 hours. it then goes OFF for 20 hours, then back on. * the Green light stays on for 8 hours. it then goes OFF for 16 hours, then back on. * the Blue light stays on for 12 hours. it then goes OFF for 12 hours, then back on.

I have them over a new planted tank and around my orchids and cactus. Everyone seems happy. They are small, as wide as a credit card, and visually do not stand out too much. There are 4 settings of brightness and each are quite different so you have a broad range of lighting options. Over my tank I have 4, so 2 sets of two, and I can adjust them separately for varied light. I will be buying more for a lower shelf of plants.

I rebuilt an old bug zapper. The old zapper had a different style ballast in it. I removed all of the components and rewired it using this ballast and a new transformer. Works exactly like it was supposed to.
