Comparing Light Bulb Efficiency & Sustainability in Kelowna

Halogen, CFLs, LEDs, Watts, Lumens – What’s the difference, and what is best for you?

Lighting a typical home accounts for about 5% of the energy use. So one of the best ways to reduce your electricity bill is to replace traditional incandescent light bulbs with compact fluorescent light bulbs (CFLs) or, even better, with light emitting diode bulbs (LEDs). LED (light-emitting diodes) lighting means sustainable lighting in so many ways. Traditional incandescent bulbs use a lot of energy to produce light and are no longer manufactured. Newer energy-saving light bulbs provide the choices in colours and light levels you require, and they are also much more efficient, saving you considerable expense in the long term.

THE VALUE OF LED

LED (light-emitting diodes) lighting means sustainable lighting in so many ways. LED lights save up to 90% energy compared to a traditional bulb with the same light output. They work by bringing together currents with a positive and negative charge to create energy released in the form of light. The result is a fast source of light that is reliable, instantaneous, and able to be dimmed. LED light sources last longer, avoiding the hassle of frequent changing of light bulbs. This significantly reduces waste but also saves you money in the long term.

ENERGY CONSUMPTION IN THE OKANAGAN

LED lights are up to 80% more efficient than traditional lighting such as fluorescent and incandescent lights. 95% of the energy in LEDs is converted into light and only 5% is wasted as heat. This is compared to fluorescent lights which convert 95% of energy to heat and only 5% into light. LED lights also draw much less power than traditional lighting; a typical 84 watt fluorescent can be replaced by a 36 watt LED to give the same level of light. There are environmental benefits as well. Less energy use reduces the demand from power plants and decreases greenhouse gas emissions.

WHAT WATTAGE

Most of us are aware that a 100-watt bulb is bright and suitable for a main light, that a 60w bulb is suitable in a lamp, and 25w bulb works where we require soft and gentle light. LED bulbs use about 10% of the energy of traditional bulbs – so 10w will give you the equivalent light output of an old 100w bulb, 6w of a 60w bulb, and so on. The main problem with incandescent bulbs is that they consume two to three times more energy than the alternatives. This coupled with a much shorter lifespan (up to 1,500 hours) than its competitors makes incandescent bulbs an expensive option. Some countries, including those in the European Union, have already banned incandescent bulbs.

KELOWNA COST COMPARISON

When comparing light bulb costs, LEDs are often considerably more expensive, but what most people don’t consider at the time of purchase are the long term ramifications of purchasing the cheaper bulb. For example, incandescents and CFLs (lasting 1,200hrs and 8,000hrs respectively) simply won’t last as long as their LED counterparts, which can last as long as 50,000hrs). This means you’ll have to purchase ‘cheaper’ bulbs several times to match the longevity of an LED. So while LEDs are more expensive, they still save money because they last a long time and have very low energy use. If everyone used LEDs, less bulbs would need to be produced, thereby reducing global waste of used light bulbs. As with other electronics, prices for LEDs are expected to come down over time as more products enter the market.
