Red Sea Max Replacement 55 Watt 50/50 Compact Fluorescent Lamp Two-Pack Bundle

The bulbs were just what the reef aquarium needed. I didn't realize how dull the prior bulbs had gotten before they finally burned out. Put in new bulbs and the improvement was drastic. Change the bulbs on a more frequent basis is the moral to the story. The vendor was great to work with.

Lost intensity in less than 4 months. I've been replacing these t5's every 7-9 months since 2011. These only lasted me 4 months and you can look at them directly as they are not as bright, the tank now has green algae, and the corals don't open as much. These where either used or defective. Sadly it took 4 months to find out. (Red Sea Max replacement bulbs.)

Excellent quality. Exactly what I needed for my starter tank

As expected

as advertised and no issues
