I received today a Mega-Ray 100W from Bobmac @ reptileuv.com for my sulcata tortoise. Right now I am getting a whopping 320uW/cm2 with my solar meter 6.2 at 14 inches. This is a lot more than my previous Powersun. Even though, I am excited with the increase readings...is this an ok amount for my sulcata?
That volume of UVB are harmful to tortoise and human. You need to rise the distance till your 6.2 read within 100 uW/cm2.
