TrueLumen 460nm Blue 18W 18" (mfg# 2301)
I purchased the 48" 54w bulb to go into my T-5 unit. This bulb is 460nm, which means that it is a deep blue with a slight purple tint. When put next to my Coral Sun 420nm, there is no comparison. This bulb is brighter and has better coloration than any bulb I have purchased in the past. The addition tipped my 50/50 spectrum slightly in favor of the blue and my corals took on a new life of their own. Colors that I have never seen before were suddenly everywhere! Highly recommended.
