Hey tater I joined that group reptile lighting on Facebook and asked about the solarmeter 6.2 and 6.5 ratios and how to calculate it. I got this from one of the members.
"Check the solarmeter ratio (6.2 divided by 6.5) for your two meters for early morning sun and mid day summer sun. You will probably get a ratio of around 60 for the early morning or late afternoon sun, and something around 30 for the mid summer sun. It is important that you check the ratio for your two meters, because it can be different depending on small production tolerances.
fluorescent lamp should have a ratio equal to medium to intensive sunlight (~40 in my example). A metal halide or mercury vapour lamp can have a lower ratio. If a lamp has half the ratio that you get for intensive sunlight, you should become very suspicious and better not use the lamp or check your reptile very frequently for burnings."
So my take on that is if I take my solarmeter 6.2 uvb readings of say example 190 and divide it by my 6.5 readings of say example 5.2 I'd get a ratio I can use to make sure it's not to much light. I'm guessing anything under 25 or 30 is to much
