Perhaps you’ve seen the television ads lately for the G.E. Reveal Brand light bulb. Or perhaps a friend, family member, or co-worker has extolled the virtues of these new-fangled purple light bulbs with you. Or maybe you’ve just seen them in action and appreciate their superior color-rendering abilities. If you’ve ever had any questions or if you just found us by accident, you’re in luck! You are about to learn everything and anything you will ever need to know about Neodymium light bulbs!
While Neodymium Light Bulbs aren’t exactly a recent invention, their popularity is with the G.E. television spots and their mention on a “prominent” talk show originating from Chicago.
What is a Neodymium Light Bulb?
A neodymium light bulb is an ordinary incandescent light bulb, except that the bulb is made of a special purple glass known as neodymium glass. Basically, it is standard light bulb glass that is “imbued” with the mineral Neodymium. Unlike other light blue filter materials that slightly attenuate a broad range of the spectrum from green through red, neodymium glass has a narrow absorption band in the yellow and yellow-orange. A neodymiub bulb glows with a whiter color like that of some halogen lamps.
The special effect of the neodymium glass filtering is to achieve more red and green output than usual for a light source of a given brightness and overall color. This causes red and green objects to look slightly brighter and more intensely colored than usual. The “triphosphor” type fluorescent lamps, including most compact fluorescent lamps, have a similar effect except that the fluorescents make bright pure reds look slightly orangish.
Neodymium bulbs are dimmer than unfiltered incandescent bulbs of the same wattage and life expectancy. Neodymium bulbs do not have increased output at any wavelength, except for an infrared band around 1064 nM where neodymium glass fluoresces.
Neodymium bulbs are available under a variety of brand names from the majors such as the G.E. Reveal, the Philips Natural Daylight and the Sylvania Daylight. Most of these brands can be found at any store that sells their other lines of light bulbs. Other Neodymium light bulb brands are bulbs such as Pure Lite, Solux, Chromalux and the like are available on line and at local light bulb retailers as well as a few companies offering high-priced premium daylight-like light sources, where the prices include hype including but not necessarily limited to health claims. Neodymium light bulbs come in a variety of life hours which vary by manufacturer from 750 to 5,000 hours.
What is Neodymium?
The symbol for Neodymium is Nd. More information can be found at www.webelements.com
Neodymium was discovered In Austria 1885 when Carl F. Auer von Welsbach separated didymium, an extract of cerite, into two new elemental components, neodymia and praseodymia, by repeated fractionation of ammonium didymium nitrate. While the free metal is a component of misch metal, (a pyrophoric alloy for lighter flints), the element was not isolated in relatively pure form until 1925. The name Neodymium has its origins in the Greek word “Neos didymos” meaning “new twin”.
