With all the introduction of LEED certification and the general trend towards green technology and home efficiency, lighting technologies have become a progressively critical element of “going green”. While these make nice catch phrases, we hope to dive deeper in to the subject and supply an excellent knowledge base for people seeking an improved understanding of energy efficiency since it relates to lighting technology.
incandescent lightIncandescent: This bulb includes glass bulb enclosure containing a wire filament. Electric current passes with the filament, which in turn gets hot and radiates the energy as visible light. Incandescent is the most frequent sort of bulb for over 100 years and has long held the regular for color rendering and consumers’ expectations of methods LED Lamps should operate, but is slowly being phased out by the Energy Independence and Security Act of 2007 due to its inefficiency. Most incandescent bulbs will be away from production at the end of 2015. Incandescent lamps also emit an important part of their energy as ultraviolet and infrared radiation, which can be invisible on the eye but potentially damaging to precious and/or light-sensitive objects.

halogen lightHalogen: A much more advanced method of incandescent, the halogen bulb uses halogen gas as well as a tungsten filament to increase light output and efficiency of the incandescent bulb. They may be known for slightly higher efficiency than typical incandescents, along with a brighter, whiter light than is provided with the original incandescent bulb. Halogen lamps are usually the very first choice for homeowners, as they are better suited for directional aiming of fixtures and give more focused beam patterns when employed in reflector-lamp formats. Halogen lamps are frequently used on movie sets and in auto headlights, and so are typically seen in spotlights and floodlights. General Electric was the first to patent and then sell this bulb in 1959. The biggest drawback? The exceptionally short lamp life, similar to those of incandescent lamps, makes these costly to maintain, especially in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t make use of a filament to produce light; instead they utilize a glass tube coated with phosphors which contains a small amount of argon and mercury vapor and electrodes at one end. When electricity is applied, the electrodes generate an invisible ultraviolet light that then excites the fluorescent coating within the tube to produce visible light. Initially the bulb requires a little longer to turn on, but when on they normally use about 70% less energy compared to the LED Candle Lights. The color quality of compact fluorescent lamps is normally subpar as opposed to halogen and incandescent, and the dimming performance will not be as smooth either, rarely getting right down to the minimum light levels that incandescent and halogen can. However, the lamp life is significantly longer – lasting as much as 10,000 hourrs plus more. Read more about replacing compact fluorescent lighting and our Color Curve Dimming products.
Metal halide: Intense discharge technology is undoubtedly an arc lamp technology that has been developed in the 1960’s. In a glass envelope filled with argon gas is an arc tube created from either quartz or ceramic and contains mercury and metal halide salts. The mix of gas, mercury and halide salts inside the tube generates an intense bright white light once heated through the electric arc contained inside. Metal halide lamps are really efficient, have excellent lamp life (some over 20,000 hours), and are capable of putting out a tremendous amount of light, so they’re typically utilized for high ceiling applications where a lot of light is necessary, stadium lights, roadway lighting, and parking area and other exterior lighting applications. The primary drawback of metal halide lamps concerns switching and dimming. Most metal halide lamps cannot activate while “hot”, which suggests if the power quickly scans the blogosphere, a restrike period of 15 to 20 mins is needed to ensure that the lamps to cool off enough to make back on again. Furthermore, they can be nearly impossible to dim. So though they are fantastic at putting out a lot of light, hopefully that’s what you want – because there is just one setting, and that’s at 100%.

annual energy savings of upgrading to LED lights graphLED: LEDs, or light-emitting diodes, can be a solid state technology that have no filament, glass envelope, gas, or mercury. LEDs produce light from the movement of electrons that results from applying an electric powered voltage difference across a semiconductor material. Each semiconductor material produces light of your specific wavelength range, so by themselves, LEDs will not be capable of producing white light. Just like other technologies, white light may be generated by using a phosphor coating, as the excitation energy is normally offered by a blue light LED. Whilst they don’t get hot inside the traditional sense, LEDs do generate heat, it’s simply not in the light path: it appears out of the opposite end, and proper dissipation on this heat through careful thermal management is crucial in determining the lifespan from the source of light. A hot LED will fail, but a highly-designed LED source of light might be rated for a 50,000 hr life and longer (in lab conditions some LEDs happen to be thought to last over 100,000 hrs). This surpasses the 48dexkpky of any incandescent bulb by hundreds and hundreds of hours. While LED home lighting is still not the most common type of residential lighting, LED T5 Tubes have been found in things for a long time like cell phones, Christmas lights, traffic lights and televisions. LED home lighting is also popular because LEDs use 90% less power than incandescent lights, are ecologically friendly, have zero UV emissions or mercury, and are very durable.
