How many incandescent light bulbs are in your home in Spruce Grove, Stony Plain, Parkland County or the Edmonton area?  This isn’t an idle question, or the beginning of a dumb joke, although the ban on incandescent bulbs that went into effect in Canada on January 1, 2014 may seem like a bad joke to some.

In case you missed it, as of January 1, old-fashioned light bulbs in their 75- and 100-watt formats are history in Canada.  You can still buy them until the old stock runs out but no more will be manufactured.  By the end of 2014 the ban will be extended to include the 40- and 60-watt versions.

There are plenty of people who are unhappy about this.  They point out that the incandescent bulb provides a soft warm dimmable light that alternatives such as compact fluorescent lights (CFLs) and LEDs can’t match.  They also note that CFLs and especially LEDs are much more expensive to buy.  And CFLs, because they contain mercury, must be disposed of in special facilities, a fact that many people using them may not be aware of.  In addition, CFLs may not work in temperatures less than minus 10 degrees Celsius.  Their lifespan can be significantly reduced if they are turned on and off rapidly, and they have a rare but nasty habit of catching on fire or smoking.

So why the ban on incandescent bulbs?  It’s all about saving the environment.  “In Canada alone, the federal government estimates that CFLs can reduce greenhouse gas emissions by more than six million tonnes a year, or the equivalent of retiring 1.4 million vehicles. In Germany, the switch to energy-efficient bulbs will save the equivalent capacity of three nuclear reactors.”  (From an article in The Globe and Mail, Dec 27, 2012, entitled “The death of the incandescent light bulb”)

More light facts:

• Roughly 90% of the energy used to operate an incandescent bulb dissipates as heat rather than being used to provide light.  (Chicken farmers note that this is actually an advantage in the spring when they are raising baby chicks in a chilly chicken coop!)
• The average life of an incandescent bulb is about 750 to 1000 hours, compared to 6,000 to 15,000 hours for a CFL (“Incandescent light bulb ban starts Jan. 1”)
• Cost to buy:  incandescent bulbs 60 to 80 cents apiece; halogen bulbs around $2 each; CFLs $2.50 to $4; LEDs about $20 per bulb.  (The possibility exists that prices for the newer bulbs, especially LEDs, will decrease once incandescent bulbs are no longer being manufactured.)
• Some incandescent bulbs will be exempt from the ban.  These include lights such as those in ovens and refrigerators that can’t be replaced with alternatives.
• Manufacturers are working on improving the quality of the light in energy-efficient  bulbs.  “Light-emitting diodes, or LEDs, are the next big thing; global lighting company Osram Sylvania, for one, believes it has a winner with its “Ultra LED,” an omnidirectional mercury-free bulb that aims to give all the warmth of a 100-watt incandescent bulb while using just 20 watts of electricity.”  (“The death of the incandescent light bulb”, The Globe and Mail)

Maybe you’ve already made a trip to your local hardware store to buy up remaining stocks of incandescent bulbs, or maybe you’ve decided to give in to the inevitable.  At least we can still buy candles if we want soft warm light with a bit of heat!
