Using the coming of LEED certification and the general trend towards green technology and home efficiency, lighting technologies have become a progressively critical aspect of “going green”. While these make nice catch phrases, we hope to dive deeper to the subject and give a solid knowledge base for those seeking a greater comprehension of energy efficiency as it relates to lighting technology.
incandescent lightIncandescent: This bulb includes glass bulb enclosure containing a wire filament. Electric current passes throughout the filament, which then warms up and radiates the vitality as visible light. Incandescent has become the most typical type of bulb in excess of 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 because of its inefficiency. Most incandescent bulbs will likely be from production in the end of 2015. Incandescent lamps also emit a substantial part of their energy as ultraviolet and infrared radiation, which can be invisible for the eye but potentially damaging to precious or light-sensitive objects.

halogen lightHalogen: An even more advanced type of incandescent, the halogen bulb uses halogen gas along with a tungsten filament to increase light output and efficiency of your incandescent light bulb. They are renowned for slightly higher efficiency than typical incandescents, plus a brighter, whiter light than is supplied through the original incandescent bulb. Halogen lamps are usually the 1st option for homeowners, as they are better suited for directional aiming of fixtures and give more focused beam patterns when utilized in reflector-lamp formats. Halogen lamps are frequently applied to movie sets and also in auto headlights, and therefore are typically seen in spotlights and floodlights. General Electric was the first one to patent then sell this bulb in 1959. The most significant drawback? The exceptionally short lamp life, similar to those of incandescent lamps, makes these costly to maintain, specifically in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t work with a filament to produce light; instead they normally use a glass tube coated with phosphors that contains a tiny bit 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 make visible light. Initially the bulb requires a little longer to change on, but when on they utilize about 70% less energy compared to LED Candle Lights. The color quality of compact fluorescent lamps is normally subpar compared to halogen and incandescent, along with the dimming performance is not as smooth either, rarely getting as a result of the minimum light levels that incandescent and halogen can. However, the lamp life is significantly longer – lasting around 10,000 hourrs plus more. Find out more about replacing compact fluorescent lighting and our Color Curve Dimming products.
Metal halide: Intense discharge technology is undoubtedly an arc lamp technology that was developed in the 1960’s. In a glass envelope filled with argon gas is an arc tube made from either quartz or ceramic and contains mercury and metal halide salts. The mix of gas, mercury and halide salts inside 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 designed for putting out a significant quantity of light, so they’re typically utilized for high ceiling applications where lots of light is essential, stadium lights, roadway lighting, and parking area along with other exterior lighting applications. The key drawback of metal halide lamps concerns switching and dimming. Most metal halide lamps cannot switch on while “hot”, which suggests in the event the power goes out, a restrike period of 15 to 20 mins is required to ensure that the lamps to cool off enough to transform back on again. In addition, they can be extremely difficult to dim. So even though they are excellent 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, certainly are 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 electric powered voltage difference across a semiconductor material. Each semiconductor material produces light of any specific wavelength range, so independently, LEDs usually are not able to producing white light. Just like other technologies, white light might be generated by using a phosphor coating, whilst the excitation energy is normally provided by a blue light LED. As they don’t get hot inside the traditional sense, LEDs do generate heat, it’s just not in the light path: it comes down out the opposite end, and proper dissipation of this heat through careful thermal management is essential in determining the lifespan in the source of light. A hot LED will fail, but a well-designed LED source of light could be rated for the 50,000 hr life and longer (in lab conditions some LEDs happen to be 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 frequent method of residential lighting, LED Tubes have already been used in things for years like mobile devices, 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.
