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!
Properly designed LEDs are wonderful for places that are hard to reach, since they last so much longer than halogen or CFL bulbs. How long they actually will last is hard to tell exactly, since in theory it will take tens of thousands of hours to reach the end of their life (or longer).roperly designed LEDs are wonderful for places that are hard to reach, since they last so much longer than halogen or CFL bulbs.
