With all the introduction of LEED certification and also the general trend towards green technology and home efficiency, lighting technology has become an extremely critical aspect of “going green”. While these make nice catch phrases, we hope to dive deeper in to the subject and provide a solid knowledge base for those seeking an improved understanding of energy efficiency because it relates to lighting technology.
incandescent lightIncandescent: This bulb consists of a glass bulb enclosure containing a wire filament. Electric current passes with the filament, which then gets hot and radiates the power as visible light. Incandescent is the most prevalent type of bulb for more than a hundred years and contains long held the regular for color rendering and consumers’ expectations of how LED Lamps should operate, but is slowly being eliminated with the Energy Independence and Security Act of 2007 due to its inefficiency. Most incandescent bulbs is going to be from production at the end of 2015. Incandescent lamps also emit an important percentage of their energy as ultraviolet and infrared radiation, which can be invisible for the human eye but potentially damaging to precious or light-sensitive objects.

halogen lightHalogen: A more advanced form of incandescent, the halogen bulb uses halogen gas plus a tungsten filament to boost light output and efficiency in the incandescent light. They can be noted for slightly higher efficiency than typical incandescents, plus a brighter, whiter light than is provided through the original incandescent bulb. Halogen lamps are often the very first choice for homeowners, because they are better suited for directional aiming of fixtures and provide more focused beam patterns when employed in reflector-lamp formats. Halogen lamps are usually used on movie sets and in auto headlights, and therefore are typically present in spotlights and floodlights. General Electric was the first one to patent and sell this bulb in 1959. The biggest drawback? The exceptionally short lamp life, similar to that from incandescent lamps, makes these expensive to maintain, specially in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t make use of a filament to make light; instead they utilize a glass tube coated with phosphors containing a modest 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 produce visible light. Initially the bulb requires a little longer to make on, but when on they use about 70% less energy compared to the LED Candle Lights. The color quality of compact fluorescent lamps is normally subpar compared with halogen and incandescent, and the dimming performance is not really as smooth either, rarely getting right down to the minimum light levels that incandescent and halogen can. However, the lamp life is significantly longer – lasting approximately ten thousand hourrs and a lot more.

Metal halide: Intense discharge technology is surely an arc lamp technology which had been developed in the 1960’s. In the glass envelope full of argon gas is an arc tube made of either quartz or ceramic and contains mercury and metal halide salts. The mix 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 really efficient, have excellent lamp life (some over 20,000 hours), and are designed for putting out an enormous level of light, so they’re typically employed for high ceiling applications where a great deal 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 activate while “hot”, which means in case the power goes out, a restrike duration of 15 to 20 minutes is essential to ensure that the lamps to cool off enough to change back on again. Additionally, they are extremely hard to dim. So though they are great at putting out a great deal of light, hopefully that’s what you would like – because 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, really 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 powered voltage difference across a semiconductor material. Each semiconductor material produces light of any specific wavelength range, so by themselves, LEDs are not capable of producing white light. Much like other technologies, white light could be generated using a phosphor coating, as the excitation energy is typically given by a blue light LED. As they don’t get hot in the traditional sense, LEDs do generate heat, it’s hardly within the light path: it comes down out the opposite end, and proper dissipation of the heat through careful thermal management is essential in determining the lifespan of your source of light. A hot LED will fail, but a highly-designed LED light source might 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 tens of thousands of hours. While LED home lights are still not the most typical method of residential lighting, LED T5 Tubes have already been employed in things for several years like mobile 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 are very durable.
