Daylight Spot Bulbs are produced using glass that thas been impregnated with a type of "rare earth" known as neodymium, which gives the glass a blue hue.
When neodymium is present, in the glass of a spot bulb, it filters out yellow light produced by normal spot bulbs, this then creates a whiter light, that is more natural in appearance. Neodymium filtered light can also enhance the appearance of greens and reds within the enclosure.
Neodymium coating reduces yellow for a whiter daytime light
Emits up to 90% of power as beneficial warming infrared rays
Optimum heat source for efficient thermoregulation and metabolism
Moderate output of UVA rays stimulate appetite and the immune system
