I am going to be getting the Arcadia D3+ T-5 22 Inch 24 Watt *12% Desert UVB* I need a new light fixture that I can mount into my new cage I am building. I know that I can get one on there but it is 40$ if that is all there is I guess that will work, but I would like it a bit cheaper if possible. I also heard something about a reflector, so maybe one of those aswell. Thanks!
Is it $40 for an arcadia fixture too? If so, that's quite cheap. If you're getting a nice bulb like that, you'll want to get a T5 high output fixture to take full advantage of it. Most of the nice fixtures come with a reflector built into them. It's just a shiny curved piece of metal that sits behind the bulb and redirects the output downward.http://www.lightyourreptiles.com/ has some good Arcadia and other lighting accessories.
I'd go with the fixture from light your reptiles - that way you know what you are getting. They are not, however the Arcadia branded fixtures, just to let you know. You can also look at grow supply stores - they are one of the other major users of T5 lighting.
