If you have the non hd version your better off ,they have the other white bulbs with better 450nm spike, you need to balance in more white channel to pull out the best colors also the red spectrum 660 spike has to be more like 40% to pull out the reds/pinks/ purples better , the problem with LED ab+ is its not as white as the real t5 ab+ which is around 15k . If you look at almost all lights with all channels on 100% the color is ................15k I understand that BRS says this and that , but historically it takes them around a year or so to realize something more to the story and change thier tune, going off their own video archives full of contradictory sentiment depending on timeline . Love em to death but trying to imitate 1 part of multi part "system" without all the rest is recipe for disaster. Unless you are coral labs , or follow the whole white paper fully , dont try to use AB+ (which is for gen3 xr30 pros anyhow, diff leds ) The known science is a 660nm spike and 15k will color SPS the most fully . Which is why they made C+ t5 bulb to begin with. If you were really slick you had KZ fiji pinks, which is a actinic blue/ red bulb and hits those same spikes . Been cookin corals for a min over here....
