This is a great solution if you are looking for reasonably priced terrarium lighting, but don't want to have to do the wiring and installation. This high out put light fixture includes one 6500 k bulb and a reflector. The engineered German made reflector makes all the difference, assuring that the light is all going where you want it, into the tank!! This light will produce almost twice as much total light as a comparable size t-12 light bulb (the old fatter fluorescent light bulbs).  A 48" t-12  bulb is rated at 2400 lumens, the 48" t-5 is rated at 5000 lumens.  The results are even better if you compare the usable out put, the polished aluminum reflector allows the fixture to produce substantially more usable light in your tank or tanks than a two tube shop light does. More light, less heat, all from a single 54watt bulb...... Green lighting indeed!! Includes the following features-
