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.
T5 power consumption is comparable to most LED fixtures
ATI bulbs are also very affordable, making them the preferred choice of hobbyists around the world.
