Causes Antibiotic resistance can also be introduced artificially into a microorganism through transformation protocols. This can be a useful way of implanting artificial genes into the microorganism. Antibiotic resistance is a consequence of evolution via natural selection.
How long do LEDs last? LEDs are notable for being extremely long-lasting products. Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!
1 LED bulbs can last up to 25 times longer than traditional 40- and 60-watt bulbs. 2  Inefficient 100-, 75-, 60- and 40-watt bulbs won't be sold in the U.S. after 2014. 3  Forecasters say LED prices will drop as the technology improves.tory Highlights. 1  LED bulbs can last up to 25 times longer than traditional 40- and 60-watt bulbs. 2  Inefficient 100-, 75-, 60- and 40-watt bulbs won't be sold in the U.S. after 2014. 3  Forecasters say LED prices will drop as the technology improves.
