I see the Zoo Med Large lamp stand only goes up to 36" are there any the are taller? I haven't been able to find them. I have a cement mix tray I'm gonna ve using for a baby tort and bought a brooder lamb. I have be testing the distance between the light(I'm testing with a regular 95w flood light cause my powersun has not arrived) and it seems I need it about 4' up to get the right temp. Maybe its because its a different time of light but it would seem I need a taller lamp. Any ideas?
