i still don't get it
okay reflectors can be flat like in a shop light \_________/, or they can be individual for each bulb. \_/\_/\_/\_/ Basically its one big sheet of metal molded so that each bulb does not share the reflector and in the end theres more light going to the tank..
Another thing to think about is # of bends. As you know AHsupply has great lights due to one reason.. their reflectors and the angle/# of bends.
