Full Spectrum Light Bulb
The Full Spectrum Light Bulb picks up where nature leaves off
, in providing a higher quality, more natural range of light that is useful for numerous purposes. When you're in the market for lighting you suddenly find a plethora of choices and varieties. With so many purposes at such a range of costs, it pays to educate yourself on the properties of these lights, and also to be aware of manufacturing differences.
WHAT IS THE SPECTRUM, ANYWAY?
To understand what 'full spectrum' means, and why it adds value to a light bulb product, you first have to shine a light on the visual band of the electromagnetic spectrum, or what is scientifically known as, a pretty rainbow. This is visual light, what can be seen by the human eye. Traditional incandescent bulbs only emit a sampling from each portion of the rainbow; fluorescent lights emit even morebut still only a small percentage of the spectrum. By extension, a full spectrum light bulb gives off the greatest amount of the color varieties in the rainbow. Though it's important to note, the range is not always consistent between products. And no artificial light can replicate sunlight fully, because the sun is bigger and brighter than a light bulb.
So why does more spectrum matter? Including a smoother, wider range of each color of the rainbow actually improves the quality of light in the room. If you've ever noticed the cool blue-green aura of a fluorescent light, or the differences in hard and soft white lights, coupled with the fixture or diffuser, and type, size and power of the bulb, you can easily see how each bulb choice effects the entire lighting of a roomwhich effects not only dcor, but mood, productivity, health and even plant growth.
Full spectrum light bulbs, viewed through a prism, make all the colors of the rainbow equally bright. This mimics actual sunlight, the most natural light there is.
WHY DO PEOPLE USE FULL SPECTRUM LIGHT BULBS?
There are a number of uses for this type of lighting; just as there are many ranges of quality in the product manufacture:
1.Light Therapy
2.Circadian Rhythm Reset
3.Health Benefits
4.Plant growth
5.Workspace Improvement
6.Art & dcor
1. LIGHT THERAPY:
If you've ever lived in isolation for an extended period of time, such as being snowed in during winter, you would know that 'cabin fever', or 'the winter blues' becomes a problem that seriously diminishes one's quality of life. Psychologists call it Seasonal Affective Disorder, or SAD. Extended bouts of depression, lack of motivation, overeating and oversleeping, compound with social withdrawal and general lack of exercise that can seriously impair not only relationships but health. Add to this living in a place like Alaska, where darkness falls for 51-67 days between November and January, and soon you have a real life problem.
Light boxes constructed with these full spectrum bulbs not only work to improve mood and health, staving off that winter dread, they also save the economic strain of wiring a crowded jumble of incandescent bulbs to achieve the 10,000 lux for light therapybrighter than most rooms, and still not as bright as sunlight. While the effectiveness of this therapy does have its skeptics, it has worked for numerous individuals who previously had dreaded the coming winter.
2. CIRCADIAN RHYTHM
Shift workers and travelers often experience trouble brought about by altering the body's natural cycles of waking and sleeping. Whether they are doctors-in-residence or public servants, world travelers or swing shift janitors, exposing the body to inconsistent sleep/wake patterns creates problems, not the least of which is insomnia and the inability to function effectively at their jobs. Light therapy helps to normalize their patterns with a faster, less expensive methodutilizing days instead of weeks, and tens, instead of thousands of dollars.
3. HEALTH BENEFITS
Other enthusiasts report numerous benefits from full spectrum lighting:
1.Stress hormone (cortisol) reduction
2.Mood improvement
3.Fewer headaches
4.Slower aging of the retina
5.Increased productivity
6.Reduced eye strain
4. PLANT GROWTH
FS lighting, or grow lights possess greater benefits for plants over standard lighting. The red and blue wavelengths of the EM spectrum activate photosynthesis, which is how plants create energy from light. These grow lights enrich plants with these proper wavelengths directly for the purpose of photosynthesis. The lights can be placed closer to the plants for added warmth and light which aids the plant's metabolism. Not only do the lights help to grow stronger and greener plants, they also highlight the plants in healthy brightness, making them look more natural and beautiful.
5. WORKSPACES AND DWELLING PLACES
With more of the work force retreating indoors, and spending their off hours indwelling on the internet, the quality of light can play a vital role in longterm health and productive capacity. Conventional indoor lighting increases glare even at lower watt levels; even older FS technology hadn't improved much from the tri-phosphor mix which has been in production since the early twentieth century. However modern technology has advanced to create scotopically-enhanced FS light.
Essentially, these new bulbs utilize the eye's rods and cones with less glare and energy consumption. By better targeting the rods indoors, they can reduce pupil size and increased visual acuitysomething traditional bulbs have long neglected. The difference, one study found, is as great as the difference between needing glasses and not needing glasses. It goes without saying that such environmental improvement would be of great benefit to any company which would prioritize employee performance, quality and accuracy over the lowest possible cost of light bulbs.
6. ART & DECOR
FS lighting creates added value for interiors, architecture, dcor, art museums and galleries, photography studios, and anywhere else of visual importance for customers or visitors. By increasing the available spectrum, colors, hues, saturations and luminescences get actively engaged by a more powerful and more efficient type of light. Compared to incandescent glare, or fluorescent colorations, full spectrum lighting presents enhanced aesthetic values to those sites that rely on visual effect most.
WHICH FULL SPECTRUM LIGHT BULBS ARE THE BEST FULL SPECTRUM LIGHT BULBS?
A box of FS bulbs will contain a graph that represents the portions of the spectrum being utilized. On a normal incandescent bulb, this graph will show a dotted line and a limited amount of wavelengths through the spectrum. As with digital pixels, the more range included, the greater the quality of light. So look for the graph that is as smooth and full as possible. Also take care to avoid any FS range that includes the UV, or ultraviolet portion of the spectrum, which we all know is harmful to skin and eyes, and also why we wear sunscreen.
Full-spectrum lights do come in all manner of bulbs; from traditional bulbs, tubes, reflectors and candles, to contemporary spirals, compact fluorescents, dimmable and 3-way bulbs. So enter the lighting aisle armed with the knowledge of your lighting needs and purposes, and create a brighter, healthier vision of your world.
