The Marine Glow definitley are a nice blue(have 18 inch over the 44 corner tank with 250mh 10k),just when i see all these other normal flur. in HD I wondered if any were equal to the ones in the LFS.I did find 2 HO bulbs brandnew out in my "stuff"(wife calls it junk

)complete with 38inch fixtures(don't remember where I got all 4).I took the black plastic lid off the tank,put a strip of plexi at each end,laid the fixtures on top and noticed a differance with how much more it lit the tank.Now for a trip to the lumber store for some nice pine board to build a canopy

and then a couple of bulbs.
