With all the development of LEED certification along with 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, hopefully to dive deeper in the subject and supply an excellent knowledge base for those seeking a better comprehension of energy efficiency because it concerns lighting technology.
incandescent lightIncandescent: This bulb includes a glass bulb enclosure containing a wire filament. Electric current passes throughout the filament, which then gets hot and radiates the vitality as visible light. Incandescent is the most common kind of bulb for over 100 years and contains long held the standard for color rendering and consumers’ expectations of methods LED Lamps should operate, but is slowly being phased out by the Energy Independence and Security Act of 2007 due to its inefficiency. Most incandescent bulbs will likely 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 are invisible towards the eye but potentially damaging to precious or light-sensitive objects.

halogen lightHalogen: A much more advanced kind of incandescent, the halogen bulb uses halogen gas along with a tungsten filament to enhance light output and efficiency in the incandescent light bulb. They can be noted for slightly higher efficiency than typical incandescents, and a brighter, whiter light than is provided from the original incandescent bulb. Halogen lamps are usually the initial option for homeowners, as they are better suited for directional aiming of fixtures and offer more focused beam patterns when used in reflector-lamp formats. Halogen lamps are frequently utilized on movie sets and in auto headlights, and are typically present in spotlights and floodlights. General Electric was the first one to patent then sell this bulb in 1959. The biggest drawback? The exceptionally short lamp life, much like that from incandescent lamps, makes these costly to maintain, specially in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t use a filament to generate light; instead they use a glass tube coated with phosphors that contains a small 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 within the tube to make visible light. Initially the bulb requires a little longer to transform on, but once on they utilize about 70% less energy than the LED Lighting. The hue quality of compact fluorescent lamps is often subpar compared with halogen and incandescent, as well as the dimming performance is just not as smooth either, rarely getting to the minimum light levels that incandescent and halogen can. However, the lamp life is significantly longer – lasting around 10,000 hourrs and a lot more. Read more about replacing compact fluorescent lighting and our Color Curve Dimming products.
Metal halide: Intense discharge technology is surely an arc lamp technology which was created in the 1960’s. Inside a glass envelope filled with argon gas is surely an arc tube made from either quartz or ceramic and features mercury and metal halide salts. The mix of gas, mercury and halide salts inside the tube generates a powerful bright white light once heated by the electric arc contained inside. Metal halide lamps are extremely efficient, have excellent lamp life (some over 20,000 hours), and are designed for putting out a huge volume of light, so they’re typically used for high ceiling applications where plenty of light is essential, stadium lights, roadway lighting, and car park and other exterior lighting applications. The primary drawback of metal halide lamps has to do with switching and dimming. Most metal halide lamps cannot switch on while “hot”, which suggests in case the power is out, a restrike time of 15 to 20 mins is necessary to ensure the lamps to cool off enough to turn back on again. In addition, they can be nearly impossible to dim. So while they are great at putting out a lot of light, hopefully that’s what you need – as there is only one setting, and that’s at 100%.

annual energy savings of upgrading to LED lights graphLED: LEDs, or light-emitting diodes, can be a solid state technology who have no filament, glass envelope, gas, or mercury. LEDs produce light with the movement of electrons that comes from applying a power voltage difference across a semiconductor material. Each semiconductor material produces light of your specific wavelength range, so independently, LEDs are not capable of producing white light. Similar to other technologies, white light can be generated using a phosphor coating, whilst the excitation energy is typically provided by a blue light LED. Whilst they don’t get hot from the traditional sense, LEDs do generate heat, it’s simply not within the light path: it comes down out your opposite end, and proper dissipation of the heat through careful thermal management is critical in determining the lifespan from the source of light. A hot LED will fail, but a well-designed LED light source can be rated for a 50,000 hr life and longer (in lab conditions some LEDs have been believed to last over 100,000 hrs). This surpasses the 48dexkpky of any incandescent bulb by thousands of hours. While LED home lighting is still not the most frequent kind of residential lighting, LED T5 Tubes have been utilized in things for many 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 they are very durable.
