I would recommend going with SB Reef when it comes to an inexpensive black box fixture. I've been using them for a few years without an issue. I had the original Reefbreeder value fixtures before, and I had issues with the LEDs burning out, or the blue LEDs turning black because they didn't have the proper uv shields on the diodes. Plus the SB Reef fixture's color/lenses were constructed with the reefer in mind. I have spoken to the owner of SB Reef several times and he told me they specifically designed the fixtures to correct all of the issues that early black boxes had. Like generic lens angles, led configuration, too many whites in the wrong spectrum ect. SB Reef also makes a retrofit upgrade for other black box fixtures for $69.95. I have a Reefbreeder value fixture you can have if you want to add the SB Retrofit.
