Broad-spectrum daylight lamp for terrariums Creates heat gradients for thermo-regulation Increases ambient air temperature Stimulates breeding behaviour and physiological well-being through UVA rays Can be combined with Night Heat Lamp or Infrared Basking Spot for a 24-hour cycle 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. Pet care bulb for use with Reptiles, Amphibians and Invertebrates only!
