Energy Efficient. LED lights are up to 80% more efficient than traditional lightingsuch 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!
THE 10-YEAR LIFESPAN ASSUMES A LOT ABOUT YOUR USAGE
Even the cheapest LED light bulbs (Philips sells some for as low as $2 per bulb) claim to have a 10-year lifespan, but it’s important to know that’s actually based on some pretty modest assumptions. If you read the fine print (notice the asterisks next to the 10-year claim in the image above), a 10-year lifespan is based on only having the bulb on for three hours per day, every day. In some households, this can be accurate, but in others, that’s laughable.
This particular 10-year claim means that the bulb can last for nearly 11,000 hours. So if we were to have the bulb on for eight hours every day (two hours in the morning and six hours in the evening, for instance—possibly longer on the weekends), this means that it would only last shy of three and a half years.
Compared to an incandescent light bulb that has an average 1,000-hour lifespan, 11,000 hours is still way better, but don’t let the 10-year claims fool you. Plus, there are plenty of other factors to keep in mind. Comparing our brand Elmer which has a burning warranty of 50,000 hours and after which 3 to 5% of light deduction add-on to the product.
