ATI Blue Plus 22,000 K. Brightest, most intense Actinic T5 HO bulb available

ATI Blue Plus T5 High Output bulbs have been tested with our Milwaukee Digital Underwater LuxMeter and tested with the highest LUX and highest PAR.

Pair up with ATI AquaBlue (12,000K super-crisp white-blue) and our Tek Micro-facet reflectors for unbelievable brightness and vivid color.

Our Milwaukee Digital LuxMeter with submersible probe was used to measure the PAR value of these bulbs. PAR (Photosynthetically Active Radiation) is a measure the amount of usable light that reaches the corals. ATI AquaBlue Special was rated at 335 PAR (48-inch bulb with Tek reflector).
