How to connect the power supply when the LED lamp is energized? The search is to get a wire directly from two ends? Do you need to be able to distinguish positive and negative?
Of course, the difference between the positive and the negative is positive, and remember that the leds are dc, and the dc is positive and negative. LED tube long legs are positive, broken leg is negative
Are you asking for 220V power? If you don't have to be a plus or minus, because the ac is not a plus or minus, you can just plug it in. Hope can help you!
The power supply is not positive and negative, and the power supply can only work under the dc environment. Normally bought LED lamp tube has built-in power, can be used directly in the lamp holder, but should be careful to remove the regenerator, short connect ballast. You can also go to LED918 for me.
Well, there is no such thing as a positive negative, you can just put it on the shelf, and if it's unique, just plug it into the socket
