    By the end of 2014, it will be difficult to find incandescent light bulbs in stores in Canada, except for certain specialty bulbs, like oven lights. The rest, including 40W, 60W, and 100W bulbs, will be gone. We shouldn’t lament their passing. While they were a great invention in their day more than a hundred years ago, they really hadn’t changed much. Their greatest drawback, the one that finally did them in, is their inefficiency: as much as 96 per cent of the power consumed by a bulb was lost as heat, not converted to light.

    One option for replacing the old incandescent bulbs is the LED. These lights can be used in the same lamps and fixtures you already own, and there have been many improvements in their design and performance in the last few years. A few popular misconceptions persist.

    The light from LED bulbs is cold and bluish

    LED lighting can be as warm as incandescent lighting if you choose the correct colour temperature. Colour temperature indicates how warm the light will be. It may seem counter-intuitive, but in measuring colour temperature, the higher the temperature, the cooler the light. The range is usually given as 1,000–10,000 K (Kelvin), and the warm, reddish-yellow light that most people think of as “normal” for a light bulb in the home occurs at the 2,700–3,000 K range. Choose bulbs with a colour temperature in that range and there should be no issue of light that’s too cool or too blue.

    LED bulbs are not dimmable

    LED lights are dimmable. There is a potential issue with dimming, however, arising from the fact that LED bulbs use much less power than incandescent bulbs. Typically you can replace a 60W incandescent bulb with a 12.5W LED. For decorative bulbs, as in a chandelier, a typical 25W incandescent bulb can be replaced by a 3.5-W LED bulb. It may be necessary to replace your dimmer with one that is compatible with the specific bulbs you are using. You may also buy LED bulbs that have the necessary circuitry built in to handle dimming. Check this before you purchase. Better, ask for a demonstration.

    LED lighting is expensive

    Prices are dropping all the time, but the average LED bulb is still more expensive than the average incandescent. However, given that LEDs use significantly less power, and last significantly longer than incandescent bulbs, there is a total cost saving over the lifetime of the bulb. While you could get  cheap incandescent bulbs for less than a dollar, they would typically have a lifespan of about 1,000 hours. The LED replacement could cost ten times more, but last up to twenty-five times longer. You save in the long term.
