How much did u pay for this?
If you're asking about ATI's powermodule, i got it for around 1,610€, or 1800$ approx.

Nice! Great detail @s_tempest !I had the chance to rent a PAR meter today (Thanks, Donny and crew at Wet Pets in Vernon, CT). This message is a bit long, but with lots of photos documenting the various settings and lighting heights I examined. Enjoy!
First picture is of the tank (on whites & blues for photo) with water depths (in ") at which measurements were taken.
- Type of meter you are using for measurements: Biotek Marine BTM3000 (manufactured by Apogee, looks to be the same as the Apogee SQ-420)
- Type of lighting: 2 AI Hydra HD, new in June 2019
- LED users if possible include percentages used for different colors: see below. I measured PAR for several different spectra
- Height of lighting over your water: see below. I measured PAR at 3 heights.
- Depth of water: 21" max. Tank is a Waterbox 130.4, 48L x 24"W x 22H
- Pumps or power heads running? no
- Any other factors that may contribute to readings such as room lighting, windows, tank in sunroom? etc.
Next, I measured PAR with all channels at 100% (UV, violet, royal blue, blue, green, deep red, & white). Three heights of lights above water level: 12", 8" & 6". ABL on figures is above water level.
Next I adjusted the lighting to what I think is the highest-intensity setting during my daily program:
With PAR measurements for this setting at 12", 8" and 6":
Next I adjusted the lighting to heavily-blues setting I run as part of my program:
And measured PAR again at 12", 8" and 6":
Lastly I tested one final lighting setting, maxxing out the blues as much as I could:
And measured PAR, but only at 6" depth:
I'm still digesting what this all means. At first cut, the PAR across the board was not as high as I was expecting. I don't like to run with much whites, so these data might make me rethink that.
