  • Nice color By Kevin on 2/19/2015

    This bulb is bright. Not dull blue.
  • Great T5 bulbs By hbobob on 1/1/2015

    I have been using these in combination with Fiji purples for many years with great results.
  • Wow! By Andrew on 3/21/2013

    I reallyshouldhave gotten these quite some time ago. Color is a crisp blue making colors seem to pop out of corals. Great bulb. Definetly my actinic T5 choice going forward.
  • My corals don't lie. By Jeremy on 7/24/2012

    After including this bulb along with a another Aqua Blue over time the coral have really taken off and the bulbs really make the colors pop also.
  • only actinic i use now By Alan on 4/3/2012

    when i first started using these bulbs i used in combo with the pure actinic, i always noiced the color these made when i opened my canopy so on a whim i went to just these after a bulb change. LOVED IT! so much pop friends come over and my tank is teh first thing they notice!!
  • Your corals will pop By Aaron on 2/18/2012

    This light was a significant upgrade from the ones that came in my fixture. So far so good!
  • Makes a difference By Clay on 12/1/2011

    wow, amazed at the difference these made over standard actinic bulbs. I used these to replace a couple of hamilton actinic bulbs and was instantly pleased with the pop of my corals.
  • Hands down the best bulb By richard on 9/14/2010

    Some people like the ATI bulbs and i have tried them but these are the best for Color, par, and longevity. There is no better.
  • Hands down the best bulb By richard on 9/14/2010

    Some people like the ATI bulb but this bulb outperforms the AtI for color performance and longevity as well as par. There is no better.
  • Quality Bulb at a discount price By Brian Blank on 11/29/2009

    I picked up two of these bulbs for a 2 x 54W retrofit kit and was really impressed with the bulbs color and PAR value comparable to the ATI Blue Plus bulbs recommended for SPS tanks looking for the benefits of actinics with the power of a daylight. Popped these two into the mix and POP went the greens and fluorescent colors in the tank. It's hard to get crappy T5's at this price.
