I’ve used this bulb in my 55-gallon reef tank for over a year. The colors of my corals look vibrant and natural. The blue light is strong, which helps my anemones stay healthy. It’s also energy efficient compared to my old T-12 bulbs.
Penelope Hardacre –
Great for both reef and cichlid tanks. The daylight balance makes fish colors pop, and the actinic part supports coral growth. I noticed less heat than previous bulbs, which is a plus in a closed tank.

Switched from a standard daylight bulb to the Reef Sun 50-50. My tank looks more natural, especially the live rock and polyps. The blue light is visible and consistent, even in low-light areas of the tank.
