Ideal for tropical and desert habitats, the day blue lamp generates a gentle blue light that enhances the color of reptiles while providing a heat source needed for a healthy reptile environment. The uncoated blue glass allows the bulb to transfer more heat to the reptile enclosure, allowing the reptile to bask in its warmth. This full-spectrum lamp emits energy across all visible wavelengths from 400nm to 700nm and UVA rays from 315nm to 400nm.
