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!
The hue of light from these LED bulbs appears more like that of the traditional incandescents. They are estimated to save up to 85% more energy than standard incandescents, with a lifespan of 20,000 to 50,000 hours, or 20 to 40 years. At seven hours a day, one bulb could last an average of 17 years.
