Thanks for sharing this info...
IMO, this SQD and %SPD is the info that's often missing when attempting to compare Grow Lights...
BTW, when you compare the PR-Boost to Photo-Boost it's clear that PR-Boost is a Full Cycle Spectrum while Photo-Boost is a Flower Spectrum...
Percentage SPD - B/G/R/FR;
- Cutter PR-Boost; 15.4% / 39.3% / 43.0% / 2.2%
- PLC Photo Boost; 9.0% / 36.0% / 52.3% / 2.7%
PC LEDs (Phosphor Converted LED) typical;
- 2700 - 3000K ~ 7 - 12% Blue; Flower
- 3000 - 4000K ~ 12 - 19% Blue; Full Cycle
- 4000 - 5000K ~ 17 - 24% Blue; Vegetative
