Chromalux® Full Spectrum A21 Frosted Bulb

Chromalux® light bulbs are made of special composition glass that is not colored or coated, but instead contains neodymium, a rare earth element used in lasers. This earth element is able to absorb yellow and other dulling components of the spectrum. As a result, the light is purified, allowing the values of violet, blue, green, and red components to be strengthened, without producing an imbalance of one color over another.
