So, I am just wondering if there are any great products that are recommended to measure the UVB in our enclosures. I'm sure there will be many using the Solarmeter 6.5, but I want to know why you use what you use and see if there are any others that compare. Also, is it truly necessary to measure UVB for most keepers? Can we just go by the recommended lamps and distances? What does everyone think?
