I have always used Philips actinics or the odd time, regular URI bulbs. A couple months ago, I was looking for new actinics. For whatever reason, could not find any in Winnipeg.
I stopped in at one little lfs and the only actinic bulbs he had, were the Hagens. At $32, [the Marine Glo], its the same as URI, but more than the Philips, so I said what the heck.
I can tell you its by a long shot the brightest and nicest actinic bulb I have ever used. The colour was stunning from it and much brighter. To our eyes, it was a bright as a vho super actinic, being driven by an Icecap.
In fairness my other actinic is older, but I cant see it next to the Marine Glo.
