Choosing on an Energy-efficient Lighting Now that a lot of governments are phasing out incandescent lights because of their inefficient energy consumption, you might think about changing over to more energy-efficient lighting. You have three choices for this: regular fluorescent, compact fluorescent (CFL) andled gu10(light-emitting diodes). Regular Fluorescent Fluorescent lighting is three-to-four times more energy-efficient than incandescent lighting. The tubes also normally last at least five-to-ten times as long. One option to consider is to buy an industrial-grade electronic ballast; most of them can accept any tube. And electronic ballasts, unlike magnetic ones, don’t make a lot of flickering or noise. Next, you’ll need to determine what colour temperature you want, in terms of the correlated colour temperature (CCT). "Warm" lamps have a low CCT (2700-3000 K), and the light appears yellowish or reddish, while "cool" lamps have a high CCT (5000-6500 K) and the light appears bluish-white. If you like the colour of incandescent lighting and would like to duplicate it, you should buy warm fluorescent tubes. If you want a slightly whiter, clearer look, you might likeg9 bulb markedbetween 3500 and 4100 K, which are good for kitchens and workspaces. For an illumination more approaching natural daylight, chooseuplighters5000-6500 K. These marked cool tubes work nicely for reading. Cool light is considered by many to be healthier, and some doctors use it to treat light disorders. Your next choice when replacing a tube is to choose the colour rendering index (CRI) you’d like. CRI numbers range in a scale from one to a hundred. The higher the number, the better and more vivid the light. Compact Fluorescent (CFL) Compact fluorescent's are beginning to displace the old-style, bulky fluorescent fixtures. CFL bulbs are smaller than conventional fluorescent tubes and can screw right into the same light fixtures you’ve been using for incandescent bulbs. In terms of usage, energy-efficiency and quality of light, CFLs are quite similar to normal fluorescent lights. But you have several varieties of CFL bulbs to choose from, and each type performs a specific function. © 2011
LED (Light-emitting Diode) Lights LED's, the newest kids on the block, have a number of significant advantages over fluorescent lights. LED's, unlike fluorescent lights, lack mercury, which fluorescent tubes give off when they shatter. LED bulbs aren’t as likely to break as fluorescent tubes, and their life is much longer. LED's attain full brightness instantly when you turn them on, and they work much better in cooler places than fluorescent lights do. You can turn LED lights on and off as often as you want without impacting their lifespan, unlike fluorescent's. And LED lights are even more energy-wise than fluorescent lights. There are a few applications where LED's are superior over-all to incandescent and fluorescent lights. In flashlights, the high initial expense of LED's is less of a factor because LED's have a longer lifespan and they drain batteries much more slowly than incandescents. LED flashlights do efficiently in cold conditions, and they focus light quite well. LED flashlights are reliable for transporting because they don’t shatter when you drop them, nor do they burn out suddenly, the way incandescent bulbs do. Unlike fluorescent and incandescent lights, LED lights, when used as coloured lights, don’t require coloured filters. That, combined with their small size and low heat output, makes LED's a great pick for Christmas lights or indicator lights. The drawbacks of LED lighting are its high initial cost and its low quality of light. For more Information on Energy Saving Light Bulbs UK visit:
