## Customer Reviews

### ⭐⭐⭐⭐⭐ It is really good I will be getting more
*by C***S on May 17, 2025*

The media could not be loaded. This really makes my biocube 32 look amazing I think you should look into this and great fit

### ⭐⭐⭐⭐⭐ Really nice general reef tank lighting
*by T***A on May 6, 2015*

These light bars, grouped together, create an excellent general lighting for an aquarium. The 8000k lights are a little on the yellow side; I found that one of those chained together with two of the 12000k lights are just about perfect for a shallow reef tank. I'd recommend double that for a deep tank. Make sure you order the correct power supply--larger is needed if you're connecting several of these together.
