People can suffer tears of the meniscus because of trauma, sports injuries or the meniscus can tear simply because it wore out. By far, the most common location for a tear is in the back, and on the inner or medial side of the knee â that is the area we call the posterior horn of the medial meniscus.he meniscus is a âcâ-shaped cartilage disk thatâs found in the knee. We have two menisci in either knee. We have the medial meniscus on the inner side of the knee and the lateral meniscus on the outer side of the knee. The menisci serve a critical function in the knee as a shock absorber or cushion.
Part I: The Cost of an Incandescent Bulb. An incandescent light bulb costs about 50 cents and lasts about 750 hours. If you were to leave a 100-watt bulb burning for 24 hours each day, 365 days per year, it would use 876 kilowatt hours per year.(1000 watts equals one kilowatt â âkiloâ means a thousand.).he cost of a kilowatt-hour of electricity varies across the country, but average cost (including all charges) is about 15 cents. Your light bulb therefore costs about $32.40 per year to operate (216 kWh X 15 cents).
So the Total Cost of Ownership for a 65W incandescent light bulb is $166.50 for producing 25,000 hours of light. What is the Total Cost of Ownership for a 12W (65W equivalent) LED light bulb? The LED light bulb itself costs about $30 up front. It uses 12W of electricity, which adds up to 300kWh over 25,000 hours.
