Red Sea Reef Spec T5 Bulb – 24W Reef Actinic Lighting
Aquaculture Technologies’ Red Sea Reef Spec T5 Bulb is a high-quality fluorescent lighting solution designed specifically for reef aquariums. Most corals are photosynthetic and rely on symbiotic algae called zooxanthellae for up to 85% of their growth and coloration. To support the development of these algae, corals require both appropriate light intensity and a precise color spectrum.
The Red Sea T5 Reef Lighting range has been developed through extensive testing to meet the specific needs of reef environments. This 24W T5 bulb delivers the necessary intensity and spectrum to promote healthy coral growth and vibrant coloration.

The coral colors have become much more vibrant since I installed this bulb. My Acropora and Pocillopora show better growth and brighter hues. The light is consistent and doesn’t cause any algae issues in my tank.
Sophie Baker –
I’ve used this bulb for three months now and it’s performing well. The lighting is strong and provides the right spectrum for my soft corals. A little dimmer than expected at the back of the tank, but overall very effective.

This is the first T5 bulb that actually brings out the natural colors of my corals. The actinic spectrum is perfect for reef tanks. I noticed a noticeable improvement in polyps extending and coral health.
