Why don't leds need a rectifier
LED tube with built-in power supply, don't tear down, the starter ballast installed leds, will burn the LED power supply and the lamp holder, starter must be removed before installation, ballast.
Leds also require a power supply to drive only the rectifier that is not the tube. Normal LED daylight tubes are not driven. You have to have a power supply drive, and you have a built-in driver but that's going to affect the life span of the power supply and you don't have to be able to do that without the wiring.
Because LED is a direct current is needed to light, and the output voltage of rectifier is an alternating current, so can't use rectifier, now LED lamp is built-in power inside, and use it every time you'd better put fluorescent original rectifier and demolition of the starter, but given the easy to use, now LED lamp can be directly on the original fluorescent lamp holder, do not need to disconnect the rectifier, only need to send a link of the starter circuit cut. Because the regenerator will provide an instantaneous high voltage, it will damage the LED
Leds are dc driven, and they don't need a rectifier. In addition, it will also affect the life of LED tubes
LED is a dc device, and the driver must be different. If you do not remove the rectifier, you may not install the LED lamp.
