With the coming of LEED certification and also the general trend towards green technology and home efficiency, lighting technologies have become an extremely critical aspect of “going green”. While these make nice catch phrases, hopefully to dive deeper into the subject and offer a good knowledge base for people seeking a greater idea of energy efficiency since it is applicable to lighting technology.
incandescent lightIncandescent: This bulb is made up of glass bulb enclosure containing a wire filament. Electric current passes through the filament, which in turn warms up and radiates the power as visible light. Incandescent has become the most prevalent form of bulb for over a hundred years and contains long held the typical for color rendering and consumers’ expectations of how LED Lamps should operate, but is slowly being phased out through the Energy Independence and Security Act of 2007 for its inefficiency. Most incandescent bulbs will be away from production at the end of 2015. Incandescent lamps also emit an important portion of their energy as ultraviolet and infrared radiation, which are invisible to the human eye but potentially damaging to precious and light-sensitive objects.

halogen lightHalogen: A far more advanced method of incandescent, the halogen bulb uses halogen gas along with a tungsten filament to increase light output and efficiency from the incandescent bulb. They may be recognized for slightly higher efficiency than typical incandescents, along with a brighter, whiter light than is supplied with the original incandescent bulb. Halogen lamps are usually the first selection for homeowners, since they are more appropriate for directional aiming of fixtures and supply more focused beam patterns when used in reflector-lamp formats. Halogen lamps are usually used on movie sets and also in auto headlights, and so are typically seen in spotlights and floodlights. General Electric was the first to patent then sell this bulb in 1959. The most significant drawback? The exceptionally short lamp life, comparable to that relating to incandescent lamps, makes these expensive to maintain, specifically in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t utilize a filament to create light; instead they utilize 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 create visible light. Initially the bulb requires a little longer to change on, but once on they utilize about 70% less energy in comparison to the LED Bulbs. The color quality of compact fluorescent lamps is normally subpar as opposed to 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 approximately 10,000 hourrs and a lot more.

Metal halide: Intense discharge technology is surely an arc lamp technology which had been created in the 1960’s. In the glass envelope full of argon gas is surely an arc tube manufactured from either quartz or ceramic and features mercury and metal halide salts. The mixture of gas, mercury and halide salts within the tube generates a powerful 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 an enormous volume of light, so they’re typically utilized for high ceiling applications where plenty of light is necessary, stadium lights, roadway lighting, and parking area and also other exterior lighting applications. The primary drawback of metal halide lamps is related to switching and dimming. Most metal halide lamps cannot start up while “hot”, which implies in case the power goes out, a restrike duration of 15 to 20 mins is required in order for the lamps to cool off enough to change back on again. Moreover, they can be extremely hard to dim. So even though they are excellent at putting out plenty of light, hopefully that’s what you need – since there is just one setting, and that’s at 100%.

annual energy savings of upgrading to Leds graphLED: LEDs, or light-emitting diodes, certainly are a solid state technology which may have no filament, glass envelope, gas, or mercury. LEDs produce light through the movement of electrons that comes from 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 not competent at producing white light. Much like other technologies, white light could be generated having a phosphor coating, as the excitation energy is usually offered by a blue light LED. As they don’t get hot within the traditional sense, LEDs do generate heat, it’s hardly in the light path: it comes down out your opposite end, and proper dissipation on this heat through careful thermal management is vital in determining the lifespan of the light source. A hot LED will fail, but a highly-designed LED source of light can be rated for 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 your incandescent bulb by hundreds and hundreds of hours. While LED home lighting is still not the most typical method of residential lighting, LED Tubes are already found in things for years like mobile 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 therefore are very durable.
