Great fixture, has worked very well for me but am changing the setup configuration so no longer need these. Finnex brand, extruded aluminum (I believe that is the material) housing, dual power supply for dawn / dusk control (2 bulbs per switch), plexi lens, and fan cooled. Bulbs have a few months of use on them but should be fine for at least another 6 months. Good condition, but note they are used. $80 per fixture.
