I found one of these at walmart for $7, holds a 18" bulb, would this be alright for my enclosure?
What are you intending it to do for your enclosure? Fluorescents are typically cool and do not provide heat. If you just want additional light, it might be okay, though the color of fluorescents is bluer than incandescents. Mixing fluorescents with incandescents can create a bizarre lighting situation.
put a reptisun 5.0 in it and through away the plastic cover and it will work perfectly.

This brings up a question I have.
Years ago a friend of mine who owned a pet shop told me that a salesman for one of the lighting companies came into his shop and info and a demo. I don't remember for sure, but I think he might have been from ESU, but I'm not positive about that.
Anyway, my friend told me that one of the things he was showing him was how important it was to have a high quality lighting fixture for a full spectrum florescent tube, or the tube wouldn't burn as bright and would also give off far less UVB. My friend told me that he put some tubes in different light fixtures that he had around his shop, including in a new shop light 4' double flourescent tube fixture, a counter type fixture, and then in some of his aquarium hoods and took some readings with him, and my friend told me that it made a really big difference on the UVB amount- the higher quality aquarium hoods showed significantly more uvb and if I remember right one of his fixtures (the shop light maybe?) showed no uvb. Keep in mind the brand of tube and model was the same for all the fixtures.
Has anyone on the forums with the appropriate tools ever tried using tubes in different fixtures to see if they get different readings in the output of uvb?
I'm just wondering if the salesman was full of it, or if there is in fact a difference in say this under the counter light vs say a more expensive fixture. I've never worried about it enough to use the more expensive fixtures, but the guy sure had my friend convinced, so I do wonder about it from time to time...

perhaps ( and this is just a guess ) they were being tested in fixtures of different wattages?
No, they were, but he was testing them in pairs so he was comparing 4' to 4' not 4' to 2'.
The other thing that crosses my mind from time to time is my friend just happened to be selling not only the tubes, but the high quality fixtures lol
But I would like to sort of put it to rest and know if someone on here ever checked...
No, more than 5 years- this was sometime in the late 90s.
And I *think* he was selling ESU reptile tubes. I just googled and the brand is still out there, but I don't see it advertised now like I did back then.
But he was making it sound like any brand of full spectrum tube would be like this, not just his brand.
And no, the rep wasn't selling fixtures, only the tubes. At least that's how I remember it. But he was concerned the tubes be used properly.
My friend had fixtures in use in the shop over aquariums and reptile enclosures that were cheap hardware store types and not the same as the more expensive fixtures he was actually selling. So they would take a new tube of x length, put it in one of the el cheapo hardware store bargain priced fixtures, get a reading, then put same tube in one of his aquarium hoods or reptile hoods, and get a reading and the readings would be different. More light and UVB from the more expensive fixture, less (and in one case none) from the el-cheapo budget hardware store or walmart fixtures.
But it wasn't the brand of tube that was supposed to be important. He was trying to demonstrate how important the quality of fixture the tube was placed in was. Supposedly the cheaper fixtures would have a negative effect on any brand of tube- and I sort of remember that he grabbed a couple of other full spectrum tube brands off the shelf and showed that as well as the brand he represented, but it's been so long and it was only my friend telling me how blown away he was by the readings so I've forgotten for sure. But my friend immediately took down all his cheaper fixtures from his reptile rack and replaced with better quality fixtures. So, I do think he was convinced anyway...
Edit- but I don't know the truth of it- I got the info second hand right after it happened, and I've wondered about it from time to time- that's why I am asking if anyone on here has actually done readings with cheap vs more expensive fixtures, because I know some of the members on here like to take readings.
