A broad-spectrum daylight lamp with a Neodymium sleeve. The spectrum is ideal for plant's photosynthesis and the UVA (ultraviolet A) light contributes to reptiles' physiological well-being. Another important factor is the heat emitted by this bulb to increase the over all ambient temperature in the terrarium. Key Features  : Broad-spectrum daylight lamp for terrariums. Creates heat gradients for thermoregulation. Increases ambient air temperature. Stimulates breeding behavior through UVA rays. Can be combined with Night Glo or Heat Glo for a 24 hours cycle. The Exo Terra Glow Light (PT2052 / PT2054 / PT2056) is perfectly suited for the Exo Terra Incandescent Bulbs.
