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!
Safer: LEDs are much cooler than incandescent lights, reducing the risk of combustion or burnt fingers. 1  Sturdier: LEDs are made with epoxy lenses, not glass, and are much more resistant to breakage. 2  Longer lasting: The same LED string could still be in use 40 holiday seasons from now.
