Using the advent of LEED certification and also the general trend towards green technology and home efficiency, lighting technology has become an increasingly critical aspect of “going green”. While these make nice catch phrases, we hope to dive deeper in the subject and provide a good knowledge base for those seeking a greater understanding of energy efficiency because it concerns lighting technology.
incandescent lightIncandescent: This bulb consists of a glass bulb enclosure containing a wire filament. Electric current passes from the filament, which then heats up and radiates the electricity as visible light. Incandescent continues to be the most common type of bulb for more than a century and contains long held the standard for color rendering and consumers’ expectations of methods LED Lamps should operate, but is slowly being phased out through the Energy Independence and Security Act of 2007 because of its inefficiency. Most incandescent bulbs will likely be away from production in the end of 2015. Incandescent lamps also emit a tremendous portion of their energy as ultraviolet and infrared radiation, that happen to be invisible to the eye but potentially damaging to precious and light-sensitive objects.

halogen lightHalogen: A more advanced method of incandescent, the halogen bulb uses halogen gas plus a tungsten filament to improve light output and efficiency in the incandescent light. They are renowned for slightly higher efficiency than typical incandescents, plus a brighter, whiter light than is supplied from the original incandescent bulb. Halogen lamps are usually the first option for homeowners, because they are more appropriate for directional aiming of fixtures and give more focused beam patterns when used in reflector-lamp formats. Halogen lamps are usually applied to movie sets and then in auto headlights, and they are typically found in spotlights and floodlights. General Electric was the first one to patent and then sell this bulb in 1959. The biggest drawback? The exceptionally short lamp life, much like that relating to incandescent lamps, makes these expensive to maintain, particularly in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t use a filament to produce light; instead they use a glass tube coated with phosphors which has a tiny bit 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 make visible light. Initially the bulb takes a little longer to change on, but once on they normally use about 70% less energy compared to LED Candle Lights. Colour quality of compact fluorescent lamps is often subpar as compared with halogen and incandescent, as well as the dimming performance is not as smooth either, rarely getting down to the minimum light levels that incandescent and halogen can. However, the lamp every day life is significantly longer – lasting approximately ten thousand hourrs plus more.

Metal halide: Intense discharge technology is undoubtedly an arc lamp technology that has been created in the 1960’s. Inside a glass envelope filled with argon gas is an arc tube made of either quartz or ceramic and possesses mercury and metal halide salts. The mixture of gas, mercury and halide salts throughout the tube generates an intense bright white light once heated from the electric arc contained inside. Metal halide lamps are extremely efficient, have excellent lamp life (some over 20,000 hours), and are capable of putting out a significant amount of light, so they’re typically used for high ceiling applications where a lot of light is necessary, stadium lights, roadway lighting, and car park as well as other exterior lighting applications. The principle drawback of metal halide lamps is related to switching and dimming. Most metal halide lamps cannot start up while “hot”, which implies if the power is out, a restrike duration of 15 to twenty minutes is necessary to ensure the lamps to cool off enough to transform back on again. In addition, these are almost impossible to dim. So although they are fantastic at putting out a great deal of light, hopefully that’s what you would like – as there is only one setting, and that’s at 100%.

annual energy savings of upgrading to LED lights graphLED: LEDs, or light-emitting diodes, are a solid state technology which may have no filament, glass envelope, gas, or mercury. LEDs produce light by 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 alone, LEDs will not be effective at producing white light. Similar to other technologies, white light could be generated using a phosphor coating, even though the excitation energy is normally provided by a blue light LED. Whilst they don’t get hot in the traditional sense, LEDs do generate heat, it’s not within the light path: it appears out of the opposite end, and proper dissipation of this heat through careful thermal management is vital in determining the lifespan of your source of light. A hot LED will fail, but a highly-designed LED light source may be rated to get a 50,000 hr life and longer (in lab conditions some LEDs are already 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 prevalent type of residential lighting, LED T5 Tubes are already employed in things for a long time like mobile devices, Christmas lights, traffic lights and televisions. LED home lights are also popular because LEDs use 90% less power than incandescent lights, are ecologically friendly, have zero UV emissions or mercury, and they are very durable.
