Underrated Bulbs Jan 5, 2022
The True Actinics may not be as popular as the blue plus or coral plus bulbs but I wouldn't run a T5 fixture without them. I run two of these and two blue plus in conjuction with some LEDs and the coloration is fantastic and my corals appear very healthy. I'm a big fan of the wide violet spectrum offered between 400 and 440nm by these, something you just can't find anywhere else.
