Blue, blue, blue


Great bulb great cool blue anybody who has a HO t5 will love the intense blue that this bulb puts out. Coral growth yes yes they are

Great price... awesome bulbs!!!


I bought a cheap 6-lamp fixture, and the 3 Actinic and 3 12K bulbs that came with it gave off an annoying light. The colors were washed out, and the water had a yellow tint. TPP had the best prices, so I bought 2 Blue+, 2 Coral+ and 2 Aquablue+. This gave me bright white lighting, with a touch of blue and a pinch of purple. I had hoped for a little more blue, but I have no complaints with the current combination.
