UVB question

[krh11b23]

I have a 6 ft by 3 ft tort table, currently using a 10.0 zoomed uvb coil bulb. I am aware of the so called blindness danger. I have broken in my bulb and my tort seems to be just fine. I ordered a 100w powersun mvb online. My question is, is it possible to have too much uvb. Can I use both of these bulbs in this enclosure. Using the mvb on the basking side and the other on the cool side or should I just get rid of the coil bulb.

Yes, it is possible to have too much UVB and there is talk that the mvb bulb can give off too much even when by itself. I would suggest just getting rid of the coil one all together, since the cool side is supposed to simulate a burrow/shaded area where there wouldn't be much UVB anyways

I agree, get rid of the coil. When I have Bowser inside, I use the Powersun with him. I use the reptisul 10.0 tube for my bearded dragons.

I raised Livingstone on Zoomed Reptisun MVB's for about 3 years. They are the best way to simulate a basking spot for a tortoise, you can even use two to spread the heat zone out. I sis this when I had him on a 5ft by 10ft table. In my opinion the danger posed by too much UVB from a mercury vapor bulb is off set by all the gains and they are FAR superior to a coil bulb or tube flourescent.

Here's a pic of the set up before he went outside

I think MVBs are better for some tortoise species rather than others. I would never use them for forest species, but I have used them for a young sulcata in the past.

I would ditch the coil and use the MVB for a sulcata. If he gets regular sunshine, you don't need any artificial UV at all. I just use regular hardware store incandescent flood bulbs for my indoor enclosures.
