Yeah it's not on the box, I emailed the company and was quoted 69 Lm/W. They take a few hours to burn in, so if you do buy some, don't worry if they don't look that bright when you first turn them on. The brightness will improve in the first couple of days use.

I was wondering also, how much lumens do those circular fluorescents give out? Coz they would be perfect for growing. Could get perfectly even light to the whole canopy with a few of em.
no idea at all.

Although I'm still kind of a new poster, I keep seeing a lot of the same comments--many of which are answered an Dr. Khronik's excellent El Cheapo Guide to Lighting. But there are a few things I'd like to add in regard to watts, lumens, cfl, hps, and efficiency and how much light you need. Maybe this should be stickied? Watts have nothing to do with light or growth. Watts measure how much power a light fixture uses to produce light. You can tell how efficient a light bulb is by looking Rating: 5
