The Bulb Breakdown
If you have ever wondered what the difference is between an LED, an Incandescent and a CFL light bulb, here’s your chance to be enlightened...
Incandescent bulbs are our old faithfuls. They are certainly a lot cheaper to buy if you’re needing a quick bulb replacement. They are readily available and sold in numerous shapes and sizes. We are a society of convenience and the incandescent bulb is certainly that. The bulb lights instantly via an electronic current that passes through the filament, heating it until it glows. Although incredibly effective at producing clear and visible light, the filament does not have a long life and it is far from energy efficient to use.
Quick Fact: Many incandescent bulbs have been phased out of production because of their carbon footprint.
CFL’s (Compact Fluorescents) are very cost effective to use. The bulbs are filled with a gas that when excited by electricity is converted into visible light. They offer up to 80% saving on consumption and their life is up to 10,000 hours. The gas however contains small traces of mercury which is harmful to the environment and the warm up time that is required to excite the gas can be a nuisance when instant light is required.
Quick Fact: Make sure you dispose of CFL bulbs correctly by contacting your local waste management to ensure that the mercury is not deposited into our environment.
LED (Light Emitting Diode) is the newest energy efficient source of light on the market. LED’s use less power ultimately reducing the carbon emissions to the ozone layer and resulting in a lower electricity bill for your household. Each LED is very small and can be housed in nearly any fitting with ease. They are up to 80% more efficient than incandescent bulbs and their life can extend up to 50,000 hours. LED’s do not require heat to function and produce visible light instantly.
Quick Fact: LED’s contain very little ultra violet radiation so they do not attract as many insects and hence the perfect product for external use.Compare: LED Lights vs CFL vs Incandescent http://www.designrecycleinc.com/led%20comp%20chart.html
