With the introduction of LEED certification as well as the general trend towards green technology and home efficiency, lighting technologies have become a progressively critical component of “going green”. While these make nice catch phrases, we hope to dive deeper in to the subject and provide a good knowledge base for anyone seeking an improved comprehension of energy efficiency as it pertains to lighting technology.
incandescent lightIncandescent: This bulb consists of a glass bulb enclosure containing a wire filament. Electric current passes throughout the filament, which then gets hotter and radiates the energy as visible light. Incandescent continues to be the most common sort of bulb for over 100 years and possesses long held the standard for color rendering and consumers’ expectations of how LED Lighting should operate, but is slowly being eliminated from the Energy Independence and Security Act of 2007 due to its inefficiency. Most incandescent bulbs will probably be away 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 to the human eye but potentially damaging to precious and light-sensitive objects.

halogen lightHalogen: A much more advanced type of incandescent, the halogen bulb uses halogen gas and a tungsten filament to enhance light output and efficiency from the incandescent bulb. These are 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 often the initial option for homeowners, since they are more appropriate for directional aiming of fixtures and offer more focused beam patterns when used in reflector-lamp formats. Halogen lamps tend to be suited for movie sets and in auto headlights, and are typically seen in spotlights and floodlights. General Electric was the first one to patent and then sell on this bulb in 1959. The greatest drawback? The exceptionally short lamp life, much like that from incandescent lamps, makes these expensive to maintain, especially in high or hard-to-reach locations.

Compact fluorescent: CFLs don’t use a filament to create light; instead they prefer a glass tube coated with phosphors containing a tiny bit 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 has a little longer to transform on, but once on they utilize about 70% less energy in comparison to the LED Candle Lights. Colour quality of compact fluorescent lamps is generally subpar compared with halogen and incandescent, and the dimming performance will not be 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 approximately ten thousand hourrs and a lot more.

Metal halide: Intense discharge technology is undoubtedly an arc lamp technology that was created in the 1960’s. Within a glass envelope full of argon gas is definitely an arc tube made from either quartz or ceramic and features mercury and metal halide salts. The mixture of gas, mercury and halide salts inside 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 capable of putting out a tremendous amount 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 lot and other exterior lighting applications. The key drawback of metal halide lamps concerns switching and dimming. Most metal halide lamps cannot switch on while “hot”, meaning if the power goes out, a restrike time of 15 to 20 minutes is required for the lamps to cool off enough to change back on again. Moreover, they may be extremely hard to dim. So even though they are wonderful at putting out a great deal of light, hopefully that’s what you need – because there is just one setting, and that’s at 100%.

annual energy savings of upgrading to Leds graphLED: LEDs, or light-emitting diodes, can be a solid state technology that have no filament, glass envelope, gas, or mercury. LEDs produce light by the movement of electrons that is a result of applying a power voltage difference across a semiconductor material. Each semiconductor material produces light of a specific wavelength range, so by themselves, LEDs are not competent at producing white light. Comparable to other technologies, white light might be generated with a phosphor coating, while the excitation energy is generally supplied by a blue light LED. While they don’t get hot in the traditional sense, LEDs do generate heat, it’s simply not in the light path: it will come the opposite end, and proper dissipation of the heat through careful thermal management is essential in determining the lifespan of your light source. A hot LED will fail, but a properly-designed LED light source can be rated for the 50,000 hr life and longer (in lab conditions some LEDs have been thought to last over 100,000 hrs). This surpasses the 48dexkpky of your incandescent bulb by tens of thousands of hours. While LED home lights are still not the most common type of residential lighting, LED Tubes have been found in things for a long time 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.
