With all the introduction of LEED certification and the general trend towards green technology and home efficiency, lighting technology has become an increasingly critical part of “going green”. While these make nice catch phrases, hopefully to dive deeper in the subject and give a solid knowledge base for all those seeking a much better comprehension of energy efficiency because it concerns lighting technology.
incandescent lightIncandescent: This bulb includes a glass bulb enclosure containing a wire filament. Electric current passes through the filament, which in turn gets hotter and radiates the power as visible light. Incandescent has been the most frequent type of bulb in excess of a century and contains long held the conventional 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 probably be out from production at the end of 2015. Incandescent lamps also emit a significant portion of their energy as ultraviolet and infrared radiation, that happen to be invisible on the eye but potentially damaging to precious and light-sensitive objects.

halogen lightHalogen: A more advanced form of incandescent, the halogen bulb uses halogen gas plus a tungsten filament to improve light output and efficiency of the incandescent light bulb. These are renowned for slightly higher efficiency than typical incandescents, as well as a brighter, whiter light than is supplied by the original incandescent bulb. Halogen lamps are generally the 1st selection for homeowners, as they are better suited for directional aiming of fixtures and supply more focused beam patterns when found in reflector-lamp formats. Halogen lamps are frequently used on movie sets and also in auto headlights, and therefore are typically found in spotlights and floodlights. General Electric was the first to patent then sell this bulb in 1959. The biggest drawback? The exceptionally short lamp life, similar to that relating to incandescent lamps, makes these costly to maintain, specially in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t use a filament to produce light; instead they normally use a glass tube coated with phosphors which has a small amount of argon and mercury vapor and electrodes at one end. When electricity is used, the electrodes generate an invisible ultraviolet light that then excites the fluorescent coating on the inside of the tube to produce visible light. Initially the bulb needs a little longer to make on, but once on they prefer about 70% less energy compared to LED Lighting. The color quality of compact fluorescent lamps is often subpar as compared with halogen and incandescent, and also the dimming performance is not really as smooth either, rarely getting as a result of the minimum light levels that incandescent and halogen can. However, the lamp every day life is significantly longer – lasting as much as 10,000 hourrs plus more. Discover 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 the glass envelope loaded with argon gas is undoubtedly an arc tube created from either quartz or ceramic and features mercury and metal halide salts. The mixture of gas, mercury and halide salts in the tube generates an intense bright white light once heated by the electric arc contained inside. Metal halide lamps are incredibly efficient, have excellent lamp life (some over 20,000 hours), and are capable of putting out a huge level of light, so they’re typically utilized for high ceiling applications where a lot of light is needed, stadium lights, roadway lighting, and parking area along with other exterior lighting applications. The primary problem with metal halide lamps has to do with switching and dimming. Most metal halide lamps cannot start up while “hot”, which suggests in the event the power quickly scans the blogosphere, a restrike period of 15 to 20 minutes is needed in order for the lamps to cool off enough to make back on again. Furthermore, they are extremely difficult to dim. So though they are great at putting out plenty of light, hopefully that’s what you wish – as there is just one single 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 who have no filament, glass envelope, gas, or mercury. LEDs produce light with the movement of electrons that results from applying an electrical voltage difference across a semiconductor material. Each semiconductor material produces light of a specific wavelength range, so independently, LEDs will not be able to producing white light. Much like other technologies, white light can be generated having a phosphor coating, even though the excitation energy is normally provided by a blue light LED. When they don’t get hot from the traditional sense, LEDs do generate heat, it’s not within the light path: it comes down the opposite end, and proper dissipation with this heat through careful thermal management is crucial in determining the lifespan of your source of light. A hot LED will fail, but a well-designed LED source of light could 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 the incandescent bulb by thousands of hours. While LED home lights are still not the most frequent method of residential lighting, LED Tubes are already used in things for several years like cell phones, 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 so are very durable.
