High Intensity 20,000 degreeK Lamps 18" 15W
This is the most perfect light for freshwater tanks!
I recently bought a new hood for my 55 gallon tank and got the long 48" light strip T8 for it and ordered one of these lights. Before, I use to get the corallife 50/50 but, from experience you have to change these bulbs twicw as much because of the blue actinc filament will go out before thr full spectrum filament. With the corallife 20, 000 K you get just as much matter of fact more blue from this bulb then any other I have gotten for any of my T8s that I have had and the tank and fish look awesome.
P.S. If you can or have the opition the best is to get two T8 ballits in the same light strip and get one full spectrum 10, 000 K and one actinc blue bulb and this way you dont have to worry about changing your bulb twice as often.
