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!
It was true of the old CFL tube TVs, and it is true of modern HDTVs. And repairing the latter is not desirable. So how long does an LED TV last before it becomes unwatchable? Numbers vary, depending on different manufacturer claims, but it is often estimated to be between 60,000 to 100,000 hours. What Causes Dimness? Why do LED TVs get dim over time?
