Topic The Cost of Clean Water and the Importance of Water Saving
Add up all the money spent on incandescents - which last from O’Neal Energy Slasher Review 750-1,000 hours - and the total savings is substantial. If a 75-watt bulb costs $1 and an LED bulb costs $50, most will opt for the incandescent. But if the LED lasts 50 times longer, you break even. That doesn't even include the time spent picking up bulbs, changing them and so forth.
Apart from the initial outlay costs, the difference in electricity use is equally dramatic, but in the LED's favor. Keep in mind that the standard label on an incandescent is how much power it consumes, not how much light it puts out. A 60-watt incandescent bulb puts out somewhat less than 900 lumens.
A LED bulb costing roughly $50 is available that is the equivalent of a 60-watt incandescent in terms of the light given off. Yet, it consumes only 2 watts of electricity. Multiply that electricity savings by 4 hours per day over 10 years and the cost savings will far outweigh the cost of the LED bulb. At 10 cents/kWh, the total savings over 10 years is about $350. So, the bulb will pay for itself in about 18 months.
At the same time, a LED bulb runs cooler so there's no danger of burning as so often happens with incandescents. A 100-watt bulb placed in a socket designed for a 40-watt will burn the covering plastic shade in a matter of hours or less. Also, how many times have you singed your skin when touching an ordinary bulb? That doesn't happen with LED bulbs.
