The early years of the 1960s consisted of a 'race' in the field of semiconductors. Then it was in this race that the LED was 'discovered' in the Fall of 1961. The LEDs were first used with computers to replace tungsten bulbs that controlled punch card readers. As technology develops so with energy efficient light bulbs develops and keep improving as the year’s passed by. Energy Efficient Light Bulbs is an important requirement for many environmentally conscious users across the country. Energy Efficient Light bulbs are becoming increasingly popular among homeowners, business people and even public officials.
A room by room guide for the right led light bulb.
Screw incandescent light bulbs will be phase out in near future due to its high use of power. There’s no need to hoarded bulbs. Remaining stocks of standard light bulbs for 100 watt, 75 watt, 60 watt, and 40 watts continue to sell until production is stop. The replacements are: Compact Fluorescent light bulb and Light Emitting Diode bulbs (LED). These are bright, use 75% to 80% less energy, and can save $60.00 to $125.00 per bulb, compare to traditional 60 watt incandescent bulb especially for homes who have about 50 bulbs and big significant in savings. But so with the investment and how much more saving for the business organization. LEDs are very expensive, up to $60.00 a bulb for some floodlights. Even in that price, these LEDs can still save you about $170.00 over a life time compared with similar incandescent. Increased completion is helping to lower the price. Starting $1.25 per bulb, CFL’s are a budget friendly choice and they’re almost as energy efficient as LEDs but take at least 30 second to reach full brightness, don’t last long, and most aren’t dimmable. Halogen bulbs, a type of incandescent remain an option but will cost you more than twice as much to power LEDs and CFLs and don’t last anyway near as long.
Family or Living room Getting the lighting in these rooms can be complicated due to many activities going on. Standard ceiling fixtures and recessed or track light provides general lighting. Table and floor lamps deliver task and accent light. If your recessed lights or track heads are adjustable, they also can be used to accent art or concentrate light in a specific area. Aim accent and task lights away from shiny surface, such as TV screens and glass framed artwork, to prevent reflected glare. For fixture use frequent on and off LED can save and survive while CFL has a short life when use for On/off cycling. Kitchen and Dinning A centrally placed ceiling fixture or recessed lights usually provide general lighting here, enhanced by under cabinet lighting for tasks. A fixture or two over the island and the table enhance general lighting, and dimming lets you switch moves and moods from homework to dining. If you have recesses lighting, the color of the cans interior, which surrounds the bulb, affects light output and light color. A shiny metal reflector casts the most light but amplify glare. A black interior trim down glare but absorbs light, so you might need a brighter bulb. Bathrooms Task lighting is delicate in the bathroom. Cool light is often recommended, but it can distort colors when applying makeup. So you may have to choose one characteristic cover the other. Decorative incandescent, such as some globe lights, aren’t part of the phase out. Remember that lights over the sink can radiate unpleasant shadows on your face; lights on the either side of the mirror or medicine cabinet are better. Recessed lights designed for wet area are fine over the shower. Bedrooms Relaxation and romance are recipe. Dimmers and warm lighting can help, so look for bulbs in the 2700 to 2900 Kelvin (k) range, for reading lamps or fixture. Position those higher than the bed to make the most of shadows. Outdoors Safely, security, and ambience are important, but you’ll also need to consider environment. Cold temperature doesn’t affect LEDs. Use floodlights or spotlights on the roof space or on the ground to illuminate dark areas for added security. Bulbs in the 2700 to 3000 Kelvin range emit a warm light that’s flattering to warm colored exteriors, and cooler light 3500K or higher complements grays and can appear brighter. Motion sensor or a photocell that turns the light on at dusk and off at dawn also helps save energy.
Types of LED Bulbs: A-Shape ("Arbitrary") A19 or general service bulbs are light bulb and we are all most familiar with and its shape. It is so universal that this is likely the first form of shape you think of when someone says "light bulb". MultiFaceted Reflector (MR)16 lamps are directional lighting of low to medium intensity, such as desk lamps, ceiling lights, track lighting, pendant fixtures, retail display lightning, landscape lighting. It is used in place of standard incandescent light bulbs for applications including residential lighting and retail lighting. Candle light LED bulb. It refer as candelabra or torpedo light bulb, our LED replacements allow you to use a fraction of the power as the incandescent light used while still maintaining a great pleasing appearance. This led bulb is replacements for chandeliers. Parabolic aluminized reflector (PAR) bulbs adjust light more accurately. Used in settled place or area and track lighting. One of the best LED light bulbs due to its directional nature. It feed similar output and beam characteristics. LED Tube is a replacement for your old fluorescent T8, T10 or T12 lamps to a better, efficient LED technology. They are bright and silent (no ballast buzzing), instant lighting.
Selecting LED Light Bulbs 1. Select Shape • Spotlights for track lighting • Floods for outdoor and recessed lights • LED candles for wall sconces and decorative fixtures • A-line bulbs for room lighting and lamps 2. Choose Brightness and Energy Efficiency • Look for bulbs with high lumens and low wattage for the best energy cost savings • Divide the lumens by the wattage to determine the best brightness-to-energy usage ratio 3. Choose Color Temperature • Soft light for indoor applications and small areas • Bright light for outdoor lighting and indoor task lighting 4. Match Fixture Base • Screw-in bases include miniature candelabra, candelabra, intermediate and medium • Pin bases typically have two pins, such as those used for many halogen lights
LEDs • Doesn’t contain Mercury and Brighten instantly. • Many are dimmable. • Many works with photocells and timers; some work with motion sensors. • Some can’t cast light in all directions. • May be bigger or heavier than other types of bulbs. • Claimed life ranges from 18 to 46 years at 3 hours per day.
Higher Kelvin (K) number = cooler light • 2700K = warm yellow • 3000K = white • 3500 to 4100K = bright white • 5000 to 6500K = bluer white
