We're just getting started with setting our tortoises up. I placed an order for a 100w mvb and a 100w che. I am now wondering if I went a bit overboard. While awaiting their arrival, I'm using an old heatlamp of the style often used in bathroom fan/light fixtures. It is 65W. To keep the temp in the basking area at a 95 or so degrees it has to be about 4ft high. I am wondering if I should have gone with the lower wattage che and mvb's??? Also, just that one light does a good job of keeping the basking area at 95 degrees and the rest of their house at about 75, so I am now thinking the mvb & che are too much together. I guess it never hurts to have extra heating options lying around though- huh?
