The Vision Daytime Basking Light is an excellent daytime heat source for smaller cages, like the Vision home for birds. While you might find your home’s ambient room temperature comfortable, for many tropical birds, it’s freezing! The Daytime Basking Light is ideal to create a natural daytime light cycle and temperature gradients in a birds cage. The gentle warmth, produced by the special filament of this bulb, penetrates deep into the feathers, skin, muscles, nerves and bones. The Daytime Basking Light is ideal to use after a bathing session or can also be used to offer sick or weaker birds heat therapy.
