Ive switched over all of my cages to the dual hoods from Diy. I have both the 18 & 24" models. They are the nicest hoods Ive ever seen or worked with. Individual control over each bulb and also a dual on/off switch also. With built in reflector to boot. I cant say enuff about them I always hated the cheap plastic hoods. After having these I'll never go back. And they arent really that much more exp than a standard hood. They work perfect with repti sun bulbs.
