Estimating Cost Savings

Estimating Cost Savings
In my home, we burn recessed incandescent floods in my kitchen ceiling. They burn 65 watts per hour,ノート パソコン These lights come in several styles such as ones that stand on posts and lights that are built into flat stones. last for about 2000 hours each, and cost $6 each. I'm considering replacing them with LED bulbs that burn only 15 Watts per hour, last 50,000 hours, and cost $40 each.led lighting LED technology can be found at a lot of gadgets these days and these have become trendy gifts that people give to their loved ones during special occasions. The cost to operate the incandescents for 50,000 hours is roughly $325.led spotlight For example, there are some LED "candles" that charge the day and are ready for use at night. This can be somewhat impractical since one must remember to place the lights in an area where they can receive direct sunlight every day. The cost to operate the LED bulb is $75. Add in the price of 23 incandescent bulbs ($138) to the operating cost of the incandescents and the total cost for 50,000 hours is $463. Add the price of the LED bulb ($40) to the operating costs for the LED and the total is $115.fluorescent lights Most solar lights use incandescent or fluorescent bulbs. These consume a lot of power and thus drain the batteries quickly. This means that standard solar lights only last for a few hours after it becomes dark. The projected savings works out to $348 ($463 - $115).

I burn my lights about 3 hours per day, or about 1100 hours per year, so I would not live long enough to realize the full savings of the LED bulb, which would last me about 45 years! All of this assumes that the cost of electricity and bulbs remain the same. But increases in the cost of electricity or decreases in the cost of LED bulbs (safe bets) would only result in greater savings.dstti LED light bulbs are a great choice for many different reasons and can be used throughout your household for many different reasons. It also assumes that the quality of the light produced by long-lasting bulbs will not degrade substantially over the years and force an early replacement.
