UVB fixture question

[Ibdmc6]

So I purchased a 36" fixture from home depot for my custom viv, but the light it comes with doesn't actually measure 36" and is pretty thin. Also, the fixture itself has a sticker that says 21 watt. I don't Want to put anything but the reptisun 10.0 in my viv, but will the 36" tube fit in the fixture? And the reptisun 10.0 is 30watt, can I use it even though that's a higher wattage than the fixture lists?

This is basically what my fixture is/looks like:

Ok so I tried putting a smaller reptisun into the fixture just to see if the end prongs would fit and it won't. Can anyone tell me a fixture I can buy online that would definitely fit a reptisun 36"?

If it's a T5 fixture it will not work. The Reptisun UVB bulbs are T8. The T8 fixture will still probably be rated lower than 30 watts, but the bulb should work fine. 36" fluorescent bulbs don't actually measure 36", that's what size fixture they fit in. In case you're wondering I've been an electrician for 15 years lol.

Thank you for replying. I've been building this viv for like a month, little by little and I'm getting close to the end so when my light fixture was the wrong one I started to get frustrated. Hopefully I can find a t8 fixture at home depot where I got the t5 one. Thanks again!
