Yes as stated by smaug it will work and follow the advisement for placement - I do recommend you change the Zilla bulb out they are not as good as the Reptisun 10.0 T 8- so look for a 22" bulb - it should go right into the fixture --- if you need help getting it placed in the tank please ask or take the screen off your tank and place the fixture on one end of the tank going width wise w/ the screen butted up to the fixture so you have the basking light and UVB on one end of the tank - make sure you have the cover off the fixture and a piece of decor directly under it ---- if you have anymore questions please askIt can work. I think that one comes with a plastic cover. If so, you want to make sure and remove it. It will need to be mounted under the screen 6-8 inches directly over the basking spot. The bulb needs to be replaced in six months. Even if it still works, the UVB output drops too low after that.
