In fact they actually emit a very broad spectrum of visible light, a very small part of which is ultraviolet. Full-spectrum light bulbs have been designed to produce light that is as close as possible to the spectrum produced by daylight, not just light that matches one point of the Kelvin temperature scale. Labels on the front of light bulb packages now state a bulb’s brightness in lumens, instead of the bulb… Size 6 Pack. The problem is, the government has banned incandescent light bulbs, and incandescent full spectrum light bulbs are currently the most effective product for the best price.

Infrared light, particularly “near infrared” light, is healing. In an incandescent bulb most of the heat energy (90%) is emitted in the infrared spectrum which is just below visible light. CFLs use power more efficiently than incandescent lamps, and therefore require less energy to create the same amount of light. Incandescent Lamp
The incandescent light bulb, incandescent lamp or incandescent light globe is a source of electric light that works by incandescence (the emission of light by an object as a result of its being heated to a high temperature). While incandescent bulbs produce light slightly more on the red side of the light spectrum, plants need light from both the red and the blue side of the spectrum to be healthy. Try This!
