Daylight Spot Bulbs are produced using glass that has been impregnated with a type of ‘rare earth’ element 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 an enclosure.
