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!
LED Life Expectancy. LEDs have a general life expectancy of 50 000 hrs. If you use your lights for 10 hours a day, this should be 13.7 yrs. If this is correct, then LEDâs are definitely an investment, even the top of the range bulb would work out to cost 2.55GBP per year. Add that to the saving you would make on energy and youâve got a very cost effective bulb!
