Thomas Edison was truly an amazing man. He persevered through numerous attempts until he finally found a way to make the incandescent bulb emit visible light (or lumens). No one can deny the value that Edison’s invention has provided in bringing light to the world at large.
In recent years, the innovation of LED lighting has improved on the foundation that Edison laid. Some people are hesitant to replace the familiar incandescent bulb with the LED, but then again, not everyone believed that indoor plumbing, the personal computer or the remote control would make life better either.
LEDs are green-friendly, having no mercury or other hazardous contents and using 50-90% less power.
Now, if going-green, lumens, watts and LEDs don’t grab your attention, maybe the topic of money will be more interesting.
A Math Lesson That Will Make the ‘Light’ Go On!
Don’t let the word “math” scare you. This is one math lesson you will be able to use in real life. Ready?
HOUSEHOLD ENERGY SAVINGS
Consider the Cost of Incandescents
Count the number of incandescent bulbs used to light your house (and garage and outdoor spots, etc.). For our purposes, we will use the number 30.
For the sake of conversation, assume that each of those is a 60-watt bulb, which uses 60 watts of energy per hour and emits 800 lumens.
Based on energy costs comparison on Wikipedia, the energy cost for a single incandescent bulb used six hours a day over a ten-year period is $158, or $15.80 per year per bulb. Therefore, the average household with 30 bulbs will pay approximately $474 a year in energy costs.
$15.80/bulb/year at 6 hours a day x the 30 bulbs in your home = $474 in electricity costs per year
Consider the Savings of LEDs
An LED, on the other hand, requires only 8 watts of energy to emit 800 lumens, and typically reduces energy costs by 50-90%.
Based on energy costs comparison on Wikipedia, the energy cost for a single LED bulb used six hours a day over a ten-year period is $26, or $2.6 per year per bulb. Therefore, the average household with 30 LED bulbs will pay approximately $78 a year in energy costs, a savings of $396 a year or almost 84% savings in energy costs.
$2.60/bulb/year at 6 hours a day x the 30 bulbs in your home = $78 in electricity costs per year
The Final Math: LEDs represent an average annual savings of nearly $400. If you use your lights more than six hours a day, your savings are even greater. For example, an average use of ten hours a day per bulb results in savings of about $660 a year, twelve hours a day represents a savings of $800 a year, and so on.
In addition to energy savings, you will also save money by reducing the number of bulbs you need to buy and replace. The incandescent bulb, on average, lasts 1 year. The LED bulb, on average, lasts 25 years!
LEDs save you money in the long run in your house and in your business.
Caveat for Small Business Owners
Statistics tell us that small businesses spend approximately $2,000 per year to light their facility. Given the squeeze on small business budgets in today’s economic environment, changing over to LED lighting is one very simple way for you to cut your expenses without any investment or time commitment.
Caveat for Commercial Businesses and Municipalities
Although the initial outlay for LED lights may seem prohibitive, mass installation has been on the rise for several years in both industrial and municipal settings. Findings have shown that the initial outlay is often recovered within 2 to 3 years due to energy savings and reduced maintenance costs. With a life span of up to 25 years, that leaves a lot of years for financial savings!
