The Benefits Of Full Spectrum Lighting

What many people do not realise is that these common forms of lighting can have a dramatic negative effect on people’s health, and that there are much better alternatives.

Neither incandescent light bulbs nor fluorescent lighting give out the full range of light that is available from the natural light of the sun. Natural sunlight is vitally important to the human body. In fact, natural sunlight is a nutrient, which is absorbed into the body, just in the same way as a nutrient taken from food would be. Sunlight has many beneficial effects on the human body. One striking effect is that on the human blood pressure. Studies of blood pressure statistics show that peoples who live very far from the equator, in the northern continents, have far higher blood pressure than those who live in the tropical regions.

Another common belief is that lack of exposure to sunlight is a major factor in increased incidence of influenza. Influenza occurs with a far higher incidence in the winter than it does in the summer, especially in countries with a temperate climate. Sunlight, in moderation, also boosts energy levels, making people who live in countries where there is a high rate of clear skies, low rainfall, and few dull days, far more likely to be physically active, and in good cardiovascular condition. The metabolism is also aided by sunlight, and it has been suggested that sunlight may even have a significant effect on a person’s intelligence levels.

The immune system is the most important factor in the human body remaining healthy, and being able to resist disease. Sunlight has been demonstrated to be a major positive contributor in maintaining a healthy and effective immune system. One of the significant reasons for the basic ill health of the modern population is the amount of time that is spent in an unnatural indoor environment. The good news is that this lack of sunshine can be to a large degree overcome by the correct use of a lighting system that creates the full range of light that the sun creates. This system of lighting is called full spectrum lighting, and it is now within the budget of not only the office and the workplace, but also the home.

That the full spectrum light bulb has been universally accepted into offices and workplaces worldwide is a matter of extreme controversy. The use of standard fluorescent light bulbs is especially contentious, as this kind of light has an extremely limited range of light. Few people today realise that fluorescent lighting was designed during World War Two as a temporary expedient, and was never meant to be used in the long term. The fact that full spectrum lighting is now so readily available, makes this even more damning on those in authority.

Save Our Planet With Led Lighting Systems

Considering the pace at which our planet is being robbed of its precious resources, that day is not far when the entire world population will be engulfed by the heat of depletion. Saving energy is on everybody’s mind but very few steps were being taken to save our planet from dying a slow, painful death.

Of course, the scenario is beginning to change. Until a few decades ago, nobody really cared about carbon emission, ozone depletion or global warming. But the pronounced impact of energy depletion on the life of every individual has changed the mindset of the public for the better. A good percentage of the population is genuinely concerned about saving earth and are willing to do what it that takes to make our planet a better place to live for the next generation.

The arrival of LED lighting systems and their increasing popularity as an energy efficient solution is the revolutionary initiative of the 21st century. LEDs first made their appearance in 1920 but their use was limited due to the high cost involved. Technological breakthroughs however, helped lower the cost of LEDs, making the technology affordable for everything from traffic lights and billboards to home lighting and halogen lamps.

Lighting is responsible for one-fourth of all energy consumptions around the world. By using energy efficient LED lighting systems for just one-twentieth of all the homes in the United States, the government can definitely, avoid the need for 13 new medium-sized (300MW) power plants every year. At the same time, the total associated greenhouse gas emissions can be lowered by up to 160 million metric tons annually, thus saving our planet from further depletion of natural resources.

LEDs offer double the efficiency of CFLs or Compact Fluorescent light bulbs that are commonly used as a green alternative in most buildings. The total absence of toxic mercury, incredibly long lifespan and faster turn-on times are other green features that make LEDs more appealing than other lighting solutions. It has been estimated by the Department of Energy that by the year 2025, LEDs could reduce national energy consumption for lighting by 29 percent, saving $125 billion on the electric bills of U.S. households.

As part of the “Save our Planet” campaign, many American cities have begun to replace street lights and parking structures with LEDs. Once this transition has been fully implemented at each and every U.S city, in less than 20 years, our planet will reveal a healthier, greener façade.

Even the car industry is switching over to LED lighting systems, especially for indicator lights on the dashboard and rear lights. A recent study suggested that if LED lights are used instead of conventional car lights, power consumption can be reduced by 90 percent for the same intensity of light. While standard halogen lights use 0.8 percent of the car’s fuel consumption, LEDs use merely 0.1 percent.

LED lighting systems are making it increasingly convenient and affordable to make our planet greener by reducing the environmental impacts that have been depleting the earth’s natural resources beyond recognition.
