It looks like one spot light covers a 3'x4' area on your son's tank, is it an SPS tank with only 2 units? It also looks like you can only get one color in each unit is this right also? Thanks!

It is a brand new tank but he will be adding SPS a bit later on when the tank matures.
I do not have a light meter but the two units had complete coverage over the whole of the tank. In order to achieve this the pendants hang 12inches above the water line. As he likes the fluorescence the LED provides, he chose blue.
I can't comment on the technical aspects or compare this lighting to other LED lighting from a technical point of view but his tank looks great.
He chose the blue because he likes to observe them fluoresce.
A three foot tank would require one pendant at a $600.00 cost which is comparable to a MH system without the added heat and high maintenace cost.
IMO, one unit would leave the edges dimmer on a 4 foot tank.
If a reefer is starting up a new tank I could not in good conscience recommend MH.
For a reefer who has MH they may decide to wait a little longer to replace their lighting. The price of LEDs will go down a bit, there will be more selection and improvements will be made.
