Compact fluorescents, also known as CFLs, provide as much light as regular incandescent bulbs while using just one-fourth of the energy. For example, a 15-watt compact fluorescent light bulb yields the same amount of light as a 60-watt incandescent bulb.
A warranty may be express or implied, depending on whether the warranty is explicitly provided (typically written) and the jurisdiction. Warranties may also state that a particular fact is true at one point in time or that the fact will be continue into the future (a promissory or continuing warranty).ut it is different from a 2 year warranty because if the buyer starts wearing the coat 5 years after buying it, and finds it wears out a year later, the buyer would have a warranty claim in Year 6. On the other hand, a 10 year performance warranty would promise that the coat would last 10 years.
A warranty is usually a written, contractual promise that attests to the quality of a specific, purchased product for a certain amount of time. Should the product become defective while it is still under warranty â say, within one year of its purchase â the company is bound by the warranty to repair or replace the item. A guarantee is also a promise regarding product quality, and it may even be written into a warranty contract. However, guarantees are generally less likely to be written, and are often not as clearly defined as warranties.
