I got an ott also and replaced it with two 100 watt equivalent cfls. They were a hell of a lot cheaper. Couldn't find anything on how many lumens the ott gives out, etc. Even their website doesn't say a whole lot about them. The glow is really subdued. Makes you wonder if there's anything to them. Only good thing is that they give out little heat. I used it to veg along with a 100 watt cfl for about a week before switching to the two cfls. The three plants I have are currently under a 150 HPS with the two 100 watt clfs as added side lighting. Everything is going about as good as can be expected. Should have them harvested by mid Dec.
