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. - 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. s.
