Actinic make them pop. But the corals look natural. Like the way they would in shallow reefs during the day. Great color rendition and shimmer. Very natural look. But ofcourse i only ran whites at 40-60% cause they too strong and blues at 80-100% to get that pop.
Lmao!!! Um your better not run them at 100% or else you wont have anything else to light. LoL. They will def light a 40B. And if you have actinics supplement you are at the sweet spot. I rather have a sol white with actinics than a sol blue.
They sell they're own controllers. But you can dim them with others. I have a reefkeeper for example that can dim them. Just about any dimmer can. Even one you make urself from rapidled.
