Which actinic are you referring to? They're 22k super blue which probally means a brilliant blue.....

Hey Peter, this may answer your question better....

"Details
Korallen Zucht 24W Super Blue T5 HO Fluorescent bulb combines the properties of a blue bulb (approximately 460nm) with an actinic 03 bulb (approximately 420nm) producing a spectrum that encourages both bluing in SPS corals and fluorescence in capable corals. Also helps balance out a washed-out/yellow hued tank. Recommend Use: as a supplement to metal halides or in combination with Fiji Purple, New Generation, Coral Light or other full spectrum T5 bulbs. (Similar to ATI Blue Plus.)"
