Uv Tube lighting

[Venom6547]

I'm constructing a 8x4x4 cage for my tegu and i have the heat bulbs they are a 65 watt indoor floodlight and theyll be mounted to 3 porcelain fixtures 2 above the basking spot and 1 in the center of the cage to spread the warmth, I was wondering if there were uvb/uva tube bulbs because i wanted to put 2 4foot tubes along the top back wall, also how much do these lightings cost are they more expensive than a mercury vapor bulb? I will be having about 1.5-2ft of substrate so the lights would be about 3ft away, I'll have to see what the temperatures are with the heat bulbs i most likely wont use all 3 but we'll see.
Thank you !

They do make 4' uvb tubes but they must be within 20" to be effective. They are a little less expensive than mvbs.

I can always install the lights on the back board a little higher than the substrate, do you know of a place that would sell them/name brands or is it one of the bulbs you would use for a salt water tank?

Zoo med makes them, they are the ReptiSun 10.0.
