What kind of UV bulb do I need to reach the bottom of a 17" deep tank?

[Bottomfeeder]

Title says all. My tank is 17" deep and I need a UV that will reach the bottom of the tank for a basking Lizard. No, it's not a climbing species. So it really needs to reach the bottom. What T-rating UV bulb do I need? And how much would it cost me at an expo for a 23" version?

id get a coil uv light and hang it down in the tank

you could just get the reptisun 10.0 and have the basking spot come within range of the uv, which is about a foot. It will cost about $20

My basking spot isn't that high. Isn't there a T-(something or other) that will reach down 17"...?

 

[Gene0514]

the T-x measurement is just the diameter of the bulb
your fixture only accepts t-8's

other option is to get a mercury vapor bulb
It should work fine over your distance
You might want to ask the vendor just in case to make sure

Won't fit in the hood...

 

[Gene0514]

it is used as the basking light and UV source
It goes into your standard incandescent hood

I don't have another fixture. There isn't a 23" flourescent bulb that will be appropriate??

 

[Gene0514]

don't you have the fixture for the basking bulb?

 

[Bottomfeeder]

Yes. It has a basking bulb in it. I'd rather get a bulb for the hood...
