The light bulb most typically found in households (incandescent) was invented way back in 1879 by Thomas Edison. Now that LED bulbs have become affordable, you need to make the switch. The average incandescent light costs consumers around $7 per year to operate. In 1976, GE engineers invented the spiral CFL, which became commercially available in 1995. The CFL bulbs were found to last 6,000-15,000 hours, much greater than the 750-1000 hours of the incandescent bulb. Drawbacks of the CFL bulb are the inclusion of mercury, limited dimming, and the fact that they are not instant-on.
LED bulbs became commercially available in 2010, have steadily improved, and come down in price. LED bulbs are instantly-on, contain no mercury, and have life spans reportedly up to 30,000 hours. LED bulbs use much less energy, consuming 1/6th of incandescent bulbs while providing similar lighting. LED bulbs have high output (lumens) and provide both cool (white) and warm (yellow) lighting, so they can be used in a variety of applications.
Although you can spend up to $30 for a high-quality LED bulb (compared to $0.41 for an incandescent), when you factor in replacement cost and the lifetime energy usage (six hours a day over ten years at 15 cents per kWh), each LED bulb would save you almost $150. Multiply that by the 50 or more bulbs you have in your house and it won’t take long to recoup your investment.
You’ll save over $7,500! – And not only that, but having an “eco-friendly home” has the potential to attract buyers to pay top dollar. Whether it’s your personal or investment property, LEDs will save you money.
