This review is for a reflector for a 24" T5 bulb; its not installed yet but from the looks of it the reflector should be very very efficient. That being said, it appears to be too short for the bulb! The reflector is only 19" long, where a 24" T4 bulb measures about 23" socket to socket. That's a good 2" of bulb with no reflector at either end. I thought perhaps there was a mix up and these are reflectors for an 18" bulb, but that doesn't make sense either, especially considering that 18" isn't even offered. I gave it 3 stars due to the missing length, other then that it looks like a great reflector.

These reflectors really reinforce my belief in getting what you pay for. They're durable, easy to install and, most importantly, they're BRIGHT! Ive used the cheap stuff in the past, and while it might get the job done, a good reflector simply gives you the most bang for your lighting bucks. If you're going to make the plunge into T-5 lighting, don't squander the gains with cheap reflectors. Aquacave is also a great place to deal with. My order was processed very quickly and the package came packed extremely well. Very satisfied.
