High Intensity 20,000 degreeK Lamps 18" 15W
VERY BRIGHT AND OUTSTANDING COLOR
I HAVE BEEN USING THE 20,000K LAMPS IN ALL MY DEEP FRESH WATER TANKS FOR A LONG TIME WITH EXCELLENT RESULTS. THE COLOR RENDITION IS SO GOOD FOR THE FISH AND PLANTS THAT I WILL NOT USE ANY OTHER BULB.

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.

This is the color spectrum you're looking for.
After talking with customer service about the "blue/white" color I wanted, and one return after trying a different bulb first, this was it. Best color I've found for my freshwater aquariums. The only reason I didn't give a 5 star is because I just had 2 bulbs in 2 fixtures die within 2 days of each other, and they're only 15 months old. Am I wrong in thinking this is too short of a lifespan? We'll see with my other aquariums (different lengths/watts) as I bought for several at the same time.
