Beautiful Color!  Even Better Growth!
ATI T5 bulbs use the latest advances in phosphors (the stuff that makes the color) and manufacturing techniques to produce bulbs with higher output, better coloration, and more stability.

The #1 selling reef specialty T5 bulb line is trusted and used at every level of the aquarium industry; manufacturers, corals farmers, shop owners and everyday hobbyists.

Blue Plus
Widely regarded as the most popular reef aquarium T5 bulb of all time, Blue Plus combines the properties of a blue bulb (approximately 460nm) with an actinic bulb (approximately 420nm). This produces an intense blue light with high PAR numbers and a light spectrum that encourages both coloration in SPS corals and fluorescence in capable corals. It also helps balance washed out/yellow-hued tanks. Recommended as a supplement to LEDs and metal halides and commonly used for sunrise and sunset applications in T5 set ups.
