So I been using a houshold flood lamp either 50w or 75w http://www.lowes.com/lowes/lkn?action=productDetail&productId=148090-3-15061&lpage=none. I tried a 100w and couldnt even get the basking spot to 95. With the 200w Im huvering 98. What is going on. And another thing the light is so bright I'm thinking it's not good plus cant get the temps right.
