Throwing a Little Light on the Subject of power conservation which is a hot topic these days, so we spoke with Mohamed Salama, Product Manager of leading lighting company El Sewedy to learn more about energy-efficient lighting, what is available, and where.
CEM: What is the difference between LED and CFL lamps?
MS: Compact fluorescent lamps (CFL) are smaller versions of standard fluorescent lamps (neon). They consume much less energy but provide light that is comparable to incandescent lights. Also, they can generally replace standard incandescent bulbs. CFLs use one-fifth to one-third the electric power of a standard lamp and last eight to twelve times longer. A CFL has a higher purchase price than an incandescent lamp but can save over five times its purchase price in electricity costs over the lamp’s lifetime.
LED is a light-emitting diode (LED) product that is assembled into a lamp (or light bulb) for use in lighting fixtures. LEDs use one-fifth to one-third of the electricity used to power a standard lamp, and last fifteen to thirty times longer. An LED lamp has a higher purchase price than an incandescent lamp but can save over fifteen times its purchase price in electricity costs over the lamp’s lifetime.
What are the price, life (working hours) and energy consumption figures of an LED lamp compared to Compact Fluorescent lamps?
CFL: Price 15-35 EGP, depending on wattage and lamp shape. Life is 6000-12000 hours, depending on the brand and quality.
LED: Price 40- 120 EGP, depending on wattage and lamp shape. Life is 15000- 35000 hours, depending on the brand and quality.
What are the available shapes, lighting colors and models for indoor use?
CFL lamps come in spiral shape, U-shape, A-shape, mini globe and globe as well as candle shape. There are also indoor reflectors and spotlights. The color options are Cool Daylight (white) and Warm Light (yellow). LED lamps are available in A-shape, globe, candle, indoor reflectors and spotlights in the same color options.
Any model mentioned above can be used in outdoor applications so long as they are protected inside a lighting fixture the same as any normal lamp. For landscaping we can use outdoor reflectors (Par lamps). Price ranges are the same as mentioned above.
What are common misconceptions concerning energy-saving lamps?
One is that they are harmful to the environment. Another is that they don’t have enough shapes or that they only come in a spiral shape. Many people believe that they are only available in white! Energy-saving lamps are available in both Warm Light and Cool Daylight tones.
Often people think incorrectly that energy-saving lamps are only imported. El Sewedy Electrical Solutions have one of the biggest factories in the Middle East and North Africa for energy-saving lamps.
Where are locations where the lamps mentioned can be bought?
They are widely available at places like Hyper Market, Spinney’s, Mahmal Supermarkets, Carrefour and lighting fixture shops. You could even try any electrician near your house, just ask for our brands, El Sewedy Lamba, El Sewedy Xtra and Megaman.
