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 white LED lamps that resulted from this invention emit very bright white light and are superior in terms of energy efficiency and lifespan when compared with incandescent and fluorescent bulbs. LEDs can last some 100,000 hours, whereas incandescent bulbs only last around 1,000.
