Light Bulb Safety

Most light bulbs may be harmful, so it is good to learn about light bulb options. The worst seem to be compact fluorescent light bulbs (CFLs) emitting mercury vapor and ultraviolet (UV) radiation. Choosing a better lighting source aids in preventing seasonally affected disorder (SAD), symptoms from using CFLs, or a lack of sunshine. Since 90% of people spend the majority of their time indoors, choosing a good lighting source is important in maintaining harmonic bio-rhythms and strong life energy. Light bulb technology has come a long way.

 

History of Light Bulbs

Thomas Alva Edison invented the first commercially available incandescent light bulb in 1879. Previous to this time, about 20 different people were designing light bulbs, but his was the first economically viable design. In 1802, Humphry Davy invented an electric arc lamp by connecting wires to a battery and a piece of carbon. The carbon glowed, producing a light. For the next seven decades, scientists around the world created various lighting elements, leading to our modern light bulb.

Incandescent light bulbs produce light through the reflection of a heated element. Unfortunately, these light bulbs are not energy-efficient, losing most of their energy as heat. In 1962 the first LED light bulb was invented by Nick Holonyak, Jr. Because LEDs do not generate heat, comparing light bulb cost of operation, LEDs cost about one-sixth the price compared to incandescent light bulbs. See this energy use calculator.

What is the Difference Between Blue Light and Full-spectrum?

Blue light, emitted from fluorescent bulbs, most LED light bulbs, and media screens suppresses melatonin production, which may contribute to sleeplessness. Between 25% to 35% of the light spectrum from these bulbs is in the blue range. Full-spectrum light is comparable to sunshine, covering the electromagnetic spectrum from infrared to near-ultraviolet, which are wavelengths useful to plants and animals. Full-spectrum lighting is not predominantly one color intensity, like typical light bulbs. See the post Color Therapy to learn about the benefits of each color.

Hazards Using Blue Light

Blue light reaches deeper into the eye than UV light and its cumulative effect has the potential of causing damage to the retina and may be implicated in the development of macular degeneration. With the use of TVs, tablets, computer screens and smartphones, the exposure to blue light is on the increase for all age ranges. The constant exposure to blue light accumulates over time and has the potential of causing major retinal damage.

For a highly recommended free downloadable program to reduce blue light emission from a computer screen, go to f.lux. This program reduces the blue light emission from a computer around sunset  when the zip code is entered. This reduces eye strain and allows the body to produce melatonin in the evening. As previously mentioned, blue light suppresses melatonin production, reducing quality sleep time during the night.

Where Can I Purchase Full Spectrum Lights?

It is very difficult to find good quality full spectrum lights. Lumiram Electric Corporation has been manufacturing Chromalux lights for a long time and still has the best value in full spectrum lighting. Lumiram has its origin in Finland, land of the midnight sun, where life must be sustained in almost total darkness for a few months of the year. Extensive research and testing there resulted in the design of this unique light source, which closely simulates natural sunlight.

Chromalux full-spectrum light bulbs may be purchased in our Store. Of course, nothing man-made compares to the full spectrum light of the sun, but this light bulb technology is a tremendous improvement on compact fluorescent lights (CFLs) and LED lighting, and other incandescent lights.

What Nutritional Supplements Support Eye Health?

For those exposed to artificial lighting, consider using Optic Plus which is an excellent product by Biotics Research for supporting eye health. “Ocular health is dependent upon many factors. As we age, we become susceptible to vision irregularities, due to environmental exposure such as ultraviolet (UV) light, poor lifestyle habits, and dietary inadequacies that can have a negative impact on eye health.” Continue reading about Optic Plus>>
