Comments This bulb is a crisp white and is fairly bright being that its only 20watts. Its a great price for a bulb that has the color you want and the spectrum that your corals desire. I was overdriving the bulb with a VHO ballast and it ended up running about 35watts. It decreased the lifespan of the bulb by about half, but it gave a lot more light output. Liked about it Good Color Reflector attached to bulb Can be overdriven Didn't like Wasn't as bright as I would have liked Price wasn't the best for just a 24 inch T12 bulb. I would like to see the reflector separate so you can attach it if you wish.
