Sorry to respond to this so late. Those are animal plastics cages. I just got a new 4x2x4 cage from them and installed 2 of the lights in it and it looks awesome. It lights up the cage well but does not light up the room so it still has the neat dark effect in the room. I will get some pictures soon. I will admitt they do not show off the animal quite as well as big flourescent lights do, but they certainly have a neater effect on the enclosure as a whole and im sure the animals appreciate not always having such a bright blinding light on all day.
