Yeah, a 65 or 75 watt is definitely much better!Thanks very much, Tom. I have a regular heat/UVA bulb that I believe is 65 or 75 watts that I could replace my MVB with, that I had no troubles with when it comes to humidity. I want to do what is best for my tortoise. I was worried if he was not out every day it would not be good for him without a UVB bulb but now that you say a few times a week that is definitely do-able for summers here in WI. (It has been very rainy this summer so I did not think I could get him out every day hence why I purchased the MVB to use this summer.) When we begin building a table for my tortoise I will make sure to follow your advice. I really appreciate your help!
