its rather orange/yellow... looks like it would be good for flowering... It gets really hot too... I had it on for taking the picture and it was already burning hot.
Eh well you could deal with the heat if it put out enough light to be put far enough from the plants and not burn them. Unfortunately 65W means it needs to be right up on the plant, and the since thats a flood light, it puts out too much heat for that. You'd be better off with some CFLs if you're lookin for something that can use a normal edison bulb fixture.
