This unit has a nice metal construction and is relatively inexpensive for a beginner hobbyist. The downside is that there are only 3 modes (Blue + White) OR Moonlight (Blue only) OR Off. Although advertised for aquariums up to 20 gallons, this mount is only 8 inches long. It's also worth noting that the distance from the edge of the mount to the center of the LEDs is 5 inches (see images). Measure your tank to see if this light is right for you. The tested color value is around 6000-7000K compared to the factory value of 18400K. I checked the PAR values and they can be found if you do a google search for "parfinderaqua".
