Hey guys! Sorry for the bombardment I'm new to the forum & have so many questions that I haven't been able to find the answers to in social media groups!

So in previous years we've always used the Exo Terra T5 VHO 12% however we purchased a Solarmeter 6.5 R as I wanted to know the actual number he was recieving!

I tested a brand new 12% bulb at the manafactures distance guideline and it read at a 1.2! We then bought the T5 VHO 14% 300, hung it at manafactures distance guideline of 30-50cm away from his shell and it was reading at a 2.5. We lowered the bulb and it's now at 25 cm away from his shell but it's reading at a 5.00 in the middle of the bulb and 4.2 at the ends.

Should I be concerned about the bulb being too close to him or trust the Solormeter and keep it at a distance that's lower than reccomended??

Thank you guys! Again sorry for all the posts I just worry so much! 💚🐢

Sorry guys I can't figure out how to edit the post I don't know how I wrote it's reading at 5.00 in the middle & 4.2 end (typo) it's not its reading at 3.00 in the middle and 2.4 at the ends

I also wanted to add the bulb is in the matching Exo Terra Terrarium Top with built in reflector 🐢💚

Those readings (3.0 at center and 2.4 at the ends) are ideal. i would keep the bulb at the distance where you got those readings.

Oh that's brilliant thank you so much! I was worried it was reading too low as I've read it should be 3.00 - 7.00

Thank you so much for the reassurance! 🥹
