Okay, so I am looking to buy a UVB light for a 40 gallon tank. (I have an ultratherm on back glass for heat so it just heats the air) I have seen so many bulbs but only about 2 light fixtures. I've concluded that spiral bulbs are a no no. Still I don't know what size to use or brand or really anything. Can someone tell me what I should buy or use? Also, this is for a box turtle I'm not sure if that makes any difference in the light. & I think this will get more answers here as opposed to the EBT page.
