With the advent 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 to the subject and offer a good knowledge base for people seeking a much better understanding of energy efficiency as it relates to lighting technology.
incandescent lightIncandescent: This bulb includes a glass bulb enclosure containing a wire filament. Electric current passes from the filament, which in turn gets hotter and radiates the power as visible light. Incandescent continues to be the most common sort of bulb more than 100 years and contains long held the conventional for color rendering and consumers’ expectations of how LED Lighting should operate, but is slowly being eliminated by the Energy Independence and Security Act of 2007 for its inefficiency. Most incandescent bulbs will probably be out of production in the end of 2015. Incandescent lamps also emit a substantial portion of their energy as ultraviolet and infrared radiation, which are invisible for the eye but potentially damaging to precious and light-sensitive objects.

halogen lightHalogen: A much more advanced form of incandescent, the halogen bulb uses halogen gas and a tungsten filament to enhance light output and efficiency from the incandescent light. 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 generally the 1st option for homeowners, because they are more appropriate for directional aiming of fixtures and provide more focused beam patterns when utilized in reflector-lamp formats. Halogen lamps are often applied to movie sets as well as in auto headlights, and are typically present in spotlights and floodlights. General Electric was the first to patent and then sell this bulb in 1959. The largest drawback? The exceptionally short lamp life, comparable to that of incandescent lamps, makes these expensive to maintain, particularly in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t work with a filament to create light; instead they use a glass tube coated with phosphors containing a tiny 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 on the inside of the tube to produce visible light. Initially the bulb requires a little longer to turn on, but when on they utilize about 70% less energy in comparison to the LED Candle Lights. The colour quality of compact fluorescent lamps is usually subpar 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 around ten thousand hourrs and much more.

Metal halide: High intensity discharge technology is undoubtedly an arc lamp technology that has been developed 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 very efficient, have excellent lamp life (some over 20,000 hours), and are capable of putting out an enormous quantity of light, so they’re typically used for high ceiling applications where plenty of light is needed, stadium lights, roadway lighting, and parking area as well as other exterior lighting applications. The key drawback of metal halide lamps has to do with switching and dimming. Most metal halide lamps cannot turn on while “hot”, which implies if the power quickly scans the blogosphere, a restrike time of 15 to twenty minutes is required in order for the lamps to cool off enough to turn back on again. Additionally, they are almost impossible to dim. So though they are excellent at putting out a great deal of light, hopefully that’s what you want – since there is only one setting, and that’s at 100%.

annual energy savings of upgrading to Leds graphLED: LEDs, or light-emitting diodes, really are a solid state technology that have no filament, glass envelope, gas, or mercury. LEDs produce light with the movement of electrons that is a result of applying an electric powered voltage difference across a semiconductor material. Each semiconductor material produces light of your specific wavelength range, so on their own, LEDs are not able to producing white light. Similar to other technologies, white light can be generated using a phosphor coating, even though the excitation energy is typically offered by a blue light LED. While they don’t get hot within the traditional sense, LEDs do generate heat, it’s hardly in the light path: it will come out the opposite end, and proper dissipation of the heat through careful thermal management is critical in determining the lifespan of your source of light. A hot LED will fail, but a nicely-designed LED source of light can be rated for a 50,000 hr life and longer (in lab conditions some LEDs have already been 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 common form of residential lighting, LED Tubes happen to be used in things for years 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 therefore are very durable.
