Using the coming of LEED certification and the general trend towards green technology and home efficiency, lighting technologies have become an increasingly critical component of “going green”. While these make nice catch phrases, hopefully to dive deeper to the subject and provide an excellent knowledge base for people seeking a better comprehension of energy efficiency as it is applicable to lighting technology.
incandescent lightIncandescent: This bulb includes glass bulb enclosure containing a wire filament. Electric current passes from the filament, which in turn gets hot and radiates the vitality as visible light. Incandescent has been the most frequent form of bulb in excess of 100 years and has long held the regular for color rendering and consumers’ expectations of how LED Lighting should operate, but is slowly being phased out with the Energy Independence and Security Act of 2007 due to the inefficiency. Most incandescent bulbs will probably be away from production in the end of 2015. Incandescent lamps also emit a substantial percentage of their energy as ultraviolet and infrared radiation, that happen to be invisible to the human eye but potentially damaging to precious and/or light-sensitive objects.

halogen lightHalogen: A far more advanced form of incandescent, the halogen bulb uses halogen gas along with a tungsten filament to improve light output and efficiency in the incandescent bulb. They can be recognized for slightly higher efficiency than typical incandescents, along with a brighter, whiter light than is supplied through the original incandescent bulb. Halogen lamps tend to be the very first option for homeowners, since they are better suited for directional aiming of fixtures and provide more focused beam patterns when used in reflector-lamp formats. Halogen lamps are frequently suited for movie sets and then in auto headlights, and therefore are typically seen in spotlights and floodlights. General Electric was the first one to patent and then sell on this bulb in 1959. The biggest drawback? The exceptionally short lamp life, much like that from incandescent lamps, makes these expensive to maintain, particularly in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t utilize a filament to generate light; instead they use a glass tube coated with phosphors containing 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 within the tube to generate visible light. Initially the bulb has a little longer to transform on, but once on they utilize about 70% less energy compared to LED Candle Lights. Colour quality of compact fluorescent lamps is normally subpar compared to halogen and incandescent, and also the dimming performance is just not 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 and more. Read more about replacing compact fluorescent lighting and our Color Curve Dimming products.
Metal halide: Intense discharge technology is definitely an arc lamp technology that was created in the 1960’s. In the glass envelope filled up with argon gas is surely an arc tube made from either quartz or ceramic and possesses mercury and metal halide salts. The mix of gas, mercury and halide salts inside the tube generates an intense bright white light once heated from the electric arc contained inside. Metal halide lamps are very efficient, have excellent lamp life (some over 20,000 hours), and are capable of putting out a significant level of light, so they’re typically utilized for high ceiling applications where lots of light is needed, stadium lights, roadway lighting, and car park along with other exterior lighting applications. The main problem with metal halide lamps is related to switching and dimming. Most metal halide lamps cannot start up while “hot”, meaning in case the power quickly scans the blogosphere, a restrike period of 15 to 20 mins is essential for the lamps to cool off enough to transform back on again. Moreover, these are nearly impossible to dim. So even though they are great at putting out lots of light, hopefully that’s what you would like – since there is merely one setting, and that’s at 100%.

annual energy savings of upgrading to Leds graphLED: LEDs, or light-emitting diodes, are a solid state technology which may have no filament, glass envelope, gas, or mercury. LEDs produce light from the movement of electrons that is a result of applying an electric voltage difference across a semiconductor material. Each semiconductor material produces light of the specific wavelength range, so on their own, LEDs are certainly not competent at producing white light. Just like other technologies, white light can be generated having a phosphor coating, while the excitation energy is typically supplied by a blue light LED. Whilst they don’t get hot in the traditional sense, LEDs do generate heat, it’s simply not within the light path: it appears out the opposite end, and proper dissipation on this heat through careful thermal management is crucial in determining the lifespan in the source of light. A hot LED will fail, but a nicely-designed LED source of light could be rated to get a 50,000 hr life and longer (in lab conditions some LEDs happen to be said to last over 100,000 hrs). This surpasses the 48dexkpky of your incandescent bulb by thousands of hours. While LED home lights are still not the most common kind of residential lighting, LED T8 Tubes are already used in things for years like cellular 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 therefore are very durable.
