Also. For what it is worth (and the people with some decades in the hobby will know these details), blueness is entirely relative.
in the horticultural world, as well as the planted tank world, 6500k bulbs are considered “blue”. Many horticultural vegetative state 6500k bulbs are actually labeled as “blue”
Around the turn of the century, 10,000k bulbs were considered by some too blue to even grow coral effectively. Anecdotal chatter on forums I mean. Don’t ask for empirical data.
As time goes on, preference has gotten SO blue in visual aesthetic that people new to the hobby now consider Radiums bulbs “too yellow” and even the Blue+ t5ho bulb to be “too white”. It seems a large number of hobbyists now genuinely wish to run a tank ONLY on royal blue LEDs. Which is odd to me. I can handle that look for a couple hours a day at most. But it gets so boring.
Overall, again, the AB+ program was never intended to be for late night viewing. It is a growth generating program that one facility felt worked well for them and people generally succeed with. If it’s too white for you. Turn the colors down. But to that point....If all you want is blue, then why buy a full spectrum led panel? Just doesn’t Make sense to buy a 190 watt (or whatever it is) led panel for nearly $900, only to wish to shut down 4 of its channels entirely. At that point just get some blue led strips and be done.
