This is from a customer PAR reading test for our lastes Mirage X300 with super blue LED layout :

Recently acquired an LEDZeal Mirage X300 to replace my 6 year old ReefBreeders photon v1. As part of the process I took PAR readings of my old fixture as a reference point. This of course means I took measurements of the X300 when I installed it and I wanted to share my findings. These fixtures pack a punch and I was impressed with the spread for the matrix/array layout. The phone/wifi controllability also makes it easy to control the lights.

The fixture I have is the "superblue layout".

Below are three different tests:

1. Peak intensity of my custom program that I am currently running over the tank (40/32/40/50)
2. 50% on all channels (50/50/50/50)
3. 100% on all channels (100/100/100/100)

All readings were taken with an Apogee SQ-120 sensor connected to my fluke meter. 

• Measurement is taken in mV and then multiplied by 5 along with a few correction factors:
  • 1.08 correction factor for underwater readings on the SQ-120 (https://www.apogeeinstruments.com/underwater-par-measurements/)
  • 1.12 spectral error when reading blue 448nm (https://www.apogeeinstruments.com/how-to-correct-for-spectral-errors-of-popular-light-sources/)
• SQ-120 does not read wavelengths under 400nm so there may be some margin of error and no correction has been done to account for this
