Apogees website shows that when measuring LEDs the readings get progressively further out the lower you go in spectrum. i believe the chart showed at worst 10% low in the blue spectrum which is admittedly what most of the PAR value is that we get out of LEDs. but 10% doesnt change the numbers that much.
Dont get me wrong, im not about to buy bigger drivers and try and push the readings higher just because they look low. if i max my light out the coralline will start to bleach and i notice some corals starting to close a bit. things just dont seem right, so i go by what my tank tells me.
