I had ordered three of those things and one of them reserved for myself as a reading lamp. I found the light after some time super uncomfortable. I thought it flatter myself, but the color is a very unpleasant way of green. The eye, the turn as white cope, but the difference is striking when one light source with real daylight spectrum faces (eg. Megaman nature color. On the slightly different color temperature, it is not here). The specified color rendering index of 98% is either deliberate deception or a misprint; With a 3-band lamps to get at best 89%. These lamps can be no question but anyway I think of color fastness. Special protection against moisture or other conditions in the terrarium also seems absent; Otherwise, the manufacturer would advertise.
