Oh Shimmy, the "Royal Blue" is J&L Aquatics's way of trying to rename the actinic blue to spure up sales. But the Actinic bulb of "Royal Blue" is the one you want. Is your fixture with 2 x 65watt bulbs?
I'm not sure how you got the renaming part to spur sales, the coralife packaging in the picture says Royal blue, i dont think J&L renamed the bulb.
It is a different spectrum of Blue provided than the regular actinics.
