The temps in Gizmo's enclosure are good but I would like to add some more light to the cool end. I think it is too dim. What can I use to add light but not heat and is not too expensive?
You can use a coil (non UVB) household bulb which will give off a very small amount of heat so the cool side temp isn't affected or you could use a standard fluorescent bulb (non UVB) to just add light also.
