These Daylight Spot Bulbs are produced using glass that has been impregnated with a type of 'rare earth' known as neodymium, which gives 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 green and red within an enclosure. 90% of the energy used by this bulb is emitted as beneficial warming infrared rays, which together with the design of the daytime spot bulb helps to efficiently direct heat to a desired basking location.
