mr. wilson, so which is the best actinic bulb that does give you the blue/green pop and are true actinics?
At this point in time there doesn't appear to be one.
I go with aesthetics and use the Aqua-Medic "blue" T5 bulb. It isn't a true actinic, but I get enough 400-500 nm light out of the metal halides as it stands.
I usually use MHL exclusively, but in the case where a dawn and dusk effect is desired, actinic T5's come in handy. Alternatively, I use blue LED's for the twilight effect. I like the rays of light and eerie effect.
in the case of MHL exclusive applications, I use a separate timer for each MHL bulb. They are timed to come on and off half an hour apart. I start with the bulbs to the "east" and end with the bulbs to the "west". It simulates a sunrise and sunset, but it lacks the black-light poster effect of lunar LED's or blue actinics.
As far as VHO goes, Coralife "actinics" have a very blue colour, but they are by no means true actinics. I prefer the low profile, cooler burning, smaller ballast, energy efficiency and longer life of T5 technology.
Philips developed both (true) actinic lighting, and T5 technology. I'm surprised they haven't combined the two yet.
It's only a matter of time before compact MHL like the Osram Powerball (the new generation of the old Powerstar) will be available in 20,000K and "blue" versions. A combination of high wattage 20,000 K's mixed with lower watt MHL blue bulbs would give the best of both worlds.
For now, we'll waste our money simultaneously pursuing T5, VHO, MHL, and LED.
