LED has a quick response. Therefore, we can repeatedly switch the LED without causing bad effect to the life span or performance of LED Lights. This alone is quite different from traditional lights. Normal incandescent light will damage the life span if being switched too often; while for fluorescent lights, frequent switching will damage the emitting electrode which will in turn decrease product life. For high pressure gas discharge lights, switching frequently will badly affect the electrode. Moreover, those light sources can’t start up in heated condition, and they have to wait until cooling down to start up again. For lighting application which needs frequent switching, led high bay certainly stands out in the crowd.
