LEDs of course. At a minimum, we want a fixture with white chips from CREE, a full spectrum of colors, integrated tank mounts (sits on the top rim of the tank). Cost is a concern but this is not a place to skimp.
The tank and stand are about a week away, so it is time to pick a light fixture manufacturer and supplier (if the two are not the same) and model.
Please stay tuned …
For the fixture, we also want a thin, edge-to-edge (for lack of a better term) unit. For a manufacturer, we chose to look at Reef Breeders first.
The next step is choose a model.
Note that like most electronic devices these days, the maker is likely not the builder. The supplier does design and maybe some final assembly, but outsources the components and build.
