Fluorescence is the emission of light by a substance which absorbed electromagnetic radiation (simplified definition). Florescence, a form of luminescence, had been observed long before it was understood with the first documented explanation written in 1852 by an Irish scientist named Sir George Stokes. Although experimental testing continued under the supervision of some brilliant scientists, fluorescent lighting did not have the commercial success of Edison’s incandescent bulbs until 1938, primarily due to patent delays and infringement claims. This, of course, is a very brief history on the invention of the fluorescent light bulb. I encourage you to research the subject in more depth. It is actually quite interesting. In the meantime, here are a few things to consider when lighting your home or office:
1. The flicker of fluorescent lighting can cause headaches, migraines, and even seizures in some people;
2. Fluorescent lighting is more economical and energy efficient than incandescent lighting;
3. Fluorescent bulbs contain mercury which could poison you if you handle broken bulbs without protection;
4. Certain Phototherapy treatments using fluorescent lighting, which mimic natural light, can help people who suffer from Seasonal Affective Disorder (SAD) and improve psoriasis and eczema;
5. The emission of blue light can disrupt the production of melatonin in the body, which helps us sleep, although it shouldn’t have too much impact unless you are exposed in the hours leading up to bed; and,
6. Eye bags, facial lines, and acne are VERY visible under fluorescent lighting, especially if it is directly above the face, making you look older and less attractive.
Although many of the myths about fluorescent lighting have been debunked, I still prefer the warm romantic glow of an incandescent bulb.
