Standard T-8 (1" dia) lamp for fluorescent aquarium light fixtures
Illuminates aquariums with 6500K daylight & 420nm actinic light
Supports photosynthetic corals while enhancing aquarium views
Reef Sun fluorescent lamps feature a 50/50 combination of 6500°K trichromatic daylight phosphor and actinic 420 phosphor. The result is high-intensity, full spectrum illumination PLUS blue actinic light essential for photosynthetic corals and invertebrates. Multipurpose lamp great for for all marine aquariums, reef aquariums, African cichlids, and discus fish.

Tips from our Techs The Blue or Actinic spectrum element in combination bulbs tends to wear out sooner than the full spectrum element. If you have the room in your fixture for an extra bulb, install the blue separately so it can be changed more often, if necessary.
