The first electric light was developed in 1809 by Humphry Davy, an English chemist. Over the years his simple design of connecting two wires to a battery which charged a charcoal strip between the other end of the wires has been continually redesigned to create better lighting. This includes the creation of the incandescent light bulb, which is currently becoming a thing of the past as newer technologies sweep the nation.

As of Jan. 1, the federal government banned manufacturing and importing both the 75-watt and 100-watt incandescent light bulbs.

Retailers have the ability to sell their existing stocks, but they will no longer be able to get more stock of the bulbs in. Instead the government is pushing for compact fluorescent lamps (CFLs) or light-emitting diodes (LED) bulbs as a more economic and environmentally friendly solution.

This December will see the 60-watt and 40-watt light bulbs be put under the same legislation and phased out of circulation.

CTV reported that a 100-watt CFL bulb costs $5, lasting for seven years. In comparison an LED bulb can cost nearly $30 though it consumes less energy and lasts for approximately 22 years.

Incandescent bulbs typically cost very little, some even as low as $1, but the consumption of electricity over a short lifespan is said to cost individuals more than the energy efficient solutions over time.

Some people have been upset over the change as incandescent light bulbs produce a soft light unlike the bright white light of the energy efficient bulbs.

CFL bulbs contain a very small amount of mercury, which means they must be recycled specially to avoid issues.

Though these are rather trivial it is important to note that incandescent bulbs also give off heat. This is essential for animal rescue centres, especially in the rescuing and rehabilitation of birds.

Many centres use 100-watt incandescent bulbs as a source of heat, but the ban has moved these shelters to purchasing large amounts of light bulbs because the alternative is to purchase expensive equipment.

In addition to these points, however, some people are upset with the government interference on consumer goods.

Canada, however, is not the first country to phase out the incandescent light bulb. In 2009 both Australia and most of Europe began phasing them out, while a ban in the United States on manufacturing the bulbs began in 2012.

The Globe and Mail reported that using an alternative, energy efficient bulb could reduce greenhouse gas emissions by six million tonnes or more.

Whether for or against the legislation which has passed, incandescent light bulbs will eventually be off the shelves never to be sold again, becoming a thing of the past.

CFLs and LEDs will have to be accepted, though currently quite expensive, economists do predict costs to lower some by 2015 for the both varieties of light bulbs.
