How the heck can anyone be happy with leds?

[Donovan Joannes]

Yes,
I'd have say the 20k radium's have more spectrums and with led's we run reefs are even bluer than that bulb, today.
I'm sorry if I took your question of 450 Royal Blues side ways in my post to yours.

It's a great question and tagging along.

No problem my friend. I really want to know this as well. Kind of pity for that guy to tell another Reefer that running all blue is okay if it is not.

Made seem less transition from 400W Radium T12 Actinic lighting to GHL Mitras and never looked back. Love LED's
