Im going to throw up my readings with my as new(used) Solarmeter 6.2 UVB meter. Not at all scientific. Please note Im using the 24" tubes not the 48" tubes. Should still be helpful.
Another disclaimer. The PureUV from AgroMax is NEW. The reptisun 10.0 tubes are on their 3rd or 4th grow. Cant remember. I used two of the Reptisun in last grows. BUT I only measured one Reptisun in the same fixture shown as I used to measure the PureUV. No need for two of the PureUV obviously. So they have been used roughly last 4 weeks of each grow 12/12 so calculate the age of them as you will. I will say they probably are still outputting close to max but I have no way to be sure.
They were turned on and warmed up for a couple minutes. I did see a diff from the first reading 5-10 seconds on compared to letting them warm up a couple minutes. I didnt let them go more because i have two week old plants under this at about 36". Probably should have covered them but it I got my measurements and was in and done quickly.
Im not posting a pic of every measurement. Just a couple of the setup so you get the idea. Tape measure is set at center line of tube. Fixture is a Sunblaster with reflector mounted to the frame of my Cree COB light. Yes its a small grow but I have 7' of vertical at least.
This information is worth exactly what you paid for it.
Readings are:
--------PureUV---------- Reptisun 10.0
---6" ---- 860 ---------------160
--12" ---- 460--------------- 70
--18"----- 241 -------------- 36
--24" ---- 150 ---------------24
These are the only two tubes I have and Im not buying more just to test and not use.
It really makes me scratch my head how people get into debates about which UV source A or B is better without any REAL measurements. Anyone got any more or better data?
