Radion g5 blue PAR

[authentic]

I have 2 Radion g5 Blue over my frag tank which is 12in deep,lights are mounted on the radion arms.I rented the apogee par meter from BRS and at full power im getting a reading of about 200-300 at the bottom of he tank on the racks. Does this seem accurate? I thought the radions would push closer to 400+ in a 12in tank.I grow sps and if the readings are correct i would run the AB program at 100%

Looking at your other threads, I assume these are XR15's over your frag tank.

Sounds about right to be honest for XR15's at that depth, depending on height over the water.

And depending on which PAR meter you had, lights that are heavily focused in the blue spectrum can at times have the PAR numbers in the meter come out lower than reality.

i agree with the above post.
2 XR30 Blue on my tank and at 12" am getting 400 par at 50% intensity.

does anyone know PAR levels for a XR15 G5 Blue at 100% AB+ ?
I am not able to rent a PAR meter here in my country...

I do have a 18" cube and was wondering if I can crank that LED up to 100%
