Arcadia Basking Solar Spotlight is available in 50, 75, 100 and 150 watts. These lamps have a dense focused ray that will provide intense heat generation. This is important for desert-based species and for these species in higher enclosures. The lamp has a nice warm color and uses standard E27 fittings. These lamps are designed to provide good heat quality and can be used with a thermostatic controller. These lamps produce substantial additional UVA to aid well-being and color vision, and should be used next to an appropriate Arcadia Reptile UVB system.
