Good bulb By John on 8/2/2015John would recommend this product to a friendI bought this bulb as a replacement bulb for my son's 40B. I forgot all about it until a few days ago when his other bulb burned out. I like it quite a bit and I plan on buying another one for a backup bulb again.
Bluer than I expected By Andy B on 10/31/2014Andy B would recommend this product to a friendHaving used 14000K bulbs in my fixture for years I changed from Aquatic life 14K to the Hamilton Technology. Huge color change to blue. Makes me wonder if my Aquatic Life bulbs were ever true 14K. Maybe they were less than 10K?
