Light-emitting diode all the potential mechanisms that can induce failures in LEDs. The most common symptom of LED (and diode laser) failure is the gradual lowering of light output and loss of efficiency. Sudden failures, although rare, can also occur. Early red LEDs were notable for their short service life. With the development of high-power LEDs, the devices are subjected to higher junction temperatures and higher current densities than traditional devices. This causes stress on the material and may cause early light-output degradation. To quantify useful lifetime in a standardized manner, some suggest using L70 or L50, which are runtimes (typically in
LED Incapacitator LED Incapacitator The Light Emitting Diode (LED) Incapacitator is a weapon designed like a flashlight. It emits an extremely bright, rapid, and well-focused series of 'differently-colored random pulses.' Before the human eyes can focus in on one frequency, another frequency comes on, causing intracranial pressure, which results in headaches, nausea, vomiting, disorientation, irritability, and visual impairment to the target (opponent). The non-lethal weapon is intended as a means of protection by law enforcement officials such as police and border patrols. The light emitted is capable of rendering opponents temporarily blind so that they can be subdued more easily. According to
