What are LEDs?
LED stands for Light Emitting Diode. LEDs are small light sources that become illuminated by the movement of electrons through a semiconductor material. Their unique characteristics include: compact size, long life and ease of maintenance, resistance to breakage and vibration, good performance in cold temperatures, lack of infrared or ultraviolet emissions, and instant-on performance. Additional benefits include the ability to be dimmed and to provide color control capabilities.
The LED Difference
LED lighting differs from incandescent, fluorescent, and HID lighting in several ways: They are more energy efficient, they produce higher quality light, they are more versatile, and they do not contain harmful mercury or lead. The efficiency of the LED means that an equal amount of illumination can be created while only consuming a fraction of the energy necessary to power alternative light sources. A defining feature of LEDs is that they emit light in a direction-specific manner. Since directional lighting reduces the need for reflectors and diffusers that can trap light, well-designed LED fixtures can deliver light efficiently to the intended location. This is unlike traditional lights which emit light and heat in all directions. Much of the light produced by these traditional lamps are lost within the fixture, reabsorbed by the lamp, or escape the fixture in a direction that is not useful for the intended application. Incandescent bulbs produce light using electricity to heat a metal filament until it becomes “white” hot. As a result, these bulbs release 90% of their energy as heat. Halogen and high intensity discharge lamps utilize a similar technology as incandescent, but have gas-filled chambers which can intensify the lighting as well as promote carbon adhesion to the filament.
Unlike other light sources, LEDs usually don’t “burn out” or fail; instead, they get progressively dimmer over time. LED useful life is typically based on the numbers of operation hours until the LED is emitting 70% of its initial light output. All Solessence products have a useful life of a minimum of 50,000 hours. A typical incandescent lamp lasts about 1,000 hours; a comparable CFL lasts 8,000-10,000 hours; a best linear fluorescent lamp can potentially last up to 30,000 hours.
LED lights are up to 80% more efficient than traditional lighting such as fluorescent and incandescent lights. 95% of the energy in LEDs is converted into light and only 5% is wasted as heat. This is compared to fluorescent lights which convert 95% of energy to heat and only 5% into light. LED lights also draw much less power than traditional lighting; a typical 84 watt fluorescent can be replaced by a 36 watt LED to give the same level of light. Less energy use reduces the demand from power plants and decreases greenhouse gas emissions. LED lights contain no toxic elements. Most offices currently use fluorescent strip lights which contain harmful chemicals such as mercury, which will contaminate the environment if improperly disposed of. Disposal of hazardous waste has to be arranged through a registered waste carrier so switching to LED avoids the cost and time implications required for compliant disposal. A U.S. Department of Energy study concluded that switching away from incandescent reduces the environmental harm of lighting by three to 10 times.
Reduced Power Consumption
Two aspects of energy efficiency are important to consider: the efficiency of the LED device itself and how well the device and fixture work together in providing the necessary. The amount of electricity used to provide the intended lighting service depends not only on the LED device, but also on the lighting fixture design. The efficiency of a poorly designed fixture that uses even the best LEDs will be only a fraction of what it would be if the fixture were well-designed. Every Solessence product is built with the highest level of craftsmanship at every step along the way.
LEDs come in multiple colors for decorative and appealing lighting. This creates endless opportunities for environments to be uniquely colored with a wide variety of lighting hues to match individual tastes.
