With the coming of LEED certification as well as the general trend towards green technology and home efficiency, lighting technologies have become an increasingly critical aspect of “going green”. While these make nice catch phrases, we hope to dive deeper to the subject and give a great knowledge base for anyone seeking an improved comprehension 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 from the filament, which then gets hotter and radiates the power as visible light. Incandescent continues to be the most frequent form of bulb for more than a century and possesses long held the typical for color rendering and consumers’ expectations of how LED Lighting 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 be away from production in the end of 2015. Incandescent lamps also emit a tremendous percentage of their energy as ultraviolet and infrared radiation, which can be invisible to the human eye but potentially damaging to precious or light-sensitive objects.

halogen lightHalogen: An even more advanced form of incandescent, the halogen bulb uses halogen gas as well as a tungsten filament to boost light output and efficiency in the incandescent light bulb. They may be renowned for slightly higher efficiency than typical incandescents, as well as a brighter, whiter light than is supplied from the original incandescent bulb. Halogen lamps are usually the first selection for homeowners, because they are more appropriate for directional aiming of fixtures and provide more focused beam patterns when found in reflector-lamp formats. Halogen lamps are often suited for 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, comparable to those of incandescent lamps, makes these expensive to maintain, especially in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t use a filament to produce light; instead they normally 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 generate visible light. Initially the bulb has a little longer to make on, but once on they prefer about 70% less energy in comparison to the LED Bulbs. The hue quality of compact fluorescent lamps is generally subpar compared to halogen and incandescent, along with the dimming performance is not as smooth either, rarely getting down to the minimum light levels that incandescent and halogen can. However, the lamp every day life is significantly longer – lasting up to 10,000 hourrs and more. Read more about replacing compact fluorescent lighting and our Color Curve Dimming products.
Metal halide: Intense discharge technology is definitely an arc lamp technology that was created in the 1960’s. In a glass envelope loaded with argon gas is definitely an arc tube created from either quartz or ceramic and has mercury and metal halide salts. The mix of gas, mercury and halide salts in the tube generates an intense bright white light once heated by the electric arc contained inside. Metal halide lamps are really efficient, have excellent lamp life (some over 20,000 hours), and are capable of putting out an enormous level of light, so they’re typically used for high ceiling applications where a great deal of light is required, stadium lights, roadway lighting, and car park as well as other exterior lighting applications. The primary problem with metal halide lamps concerns switching and dimming. Most metal halide lamps cannot switch on while “hot”, which suggests in the event the power quickly scans the blogosphere, a restrike time period of 15 to twenty or so minutes is necessary in order for the lamps to cool off enough to turn back on again. In addition, these are extremely difficult to dim. So though they are excellent at putting out lots 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 Leds graphLED: LEDs, or light-emitting diodes, certainly are a solid state technology who have no filament, glass envelope, gas, or mercury. LEDs produce light from the movement of electrons that comes from applying an electric powered voltage difference across a semiconductor material. Each semiconductor material produces light of your specific wavelength range, so independently, LEDs are not able to producing white light. Similar to other technologies, white light may be generated using a phosphor coating, even though the excitation energy is usually supplied by a blue light LED. Whilst they don’t get hot from the traditional sense, LEDs do generate heat, it’s not inside the light path: it comes out of the opposite end, and proper dissipation of this heat through careful thermal management is vital in determining the lifespan in the source of light. A hot LED will fail, but a well-designed LED light source might be rated for the 50,000 hr life and longer (in lab conditions some LEDs happen to be believed to last over 100,000 hrs). This surpasses the 48dexkpky of the incandescent bulb by tens of thousands of hours. While LED home lighting is still not the most common method of residential lighting, LED T8 Tubes are already found in things for several years like cell 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.
