The Reef Sun 50/50 Fluorescent Bulb offers a powerful balance of trichromatic daylight phosphor and actinic 420 phosphor, all in the same bulb. This unique illumination combination creates the ultimate environment for your marine, reef, African Cichlid, or Discus aquarium. The shorter length blue waves penetrate deeper to provide corals and plants what they need to carry on photosynthesis. The longer 6500K daylight waves provide natural color enhancement as well as optimum viewing light for your aquarium. These effective bulbs last an amazing 10,000 hours!

Great Cichlid bulb


Put this bulb in my cichlid tank. Brings out the colors of the fish in the most amazing ways. Makes all the rock work look vibrant and the fish seem to be happier with it. Great blue color.
