Please Note
A. If the LED 2D bulb doesn't work.
This is absolutely caused by the high frequency ballast inside your fixture. The ballast is an electronic component which regulates the electrical current in fluorescent tubes. LED tube lights do not require ballast, since they can be powered directly by household wiring.
B. How to remove the ballast?
1. Normally, Ballast had a black and white wire on the input side (120V). It also had two red and two blue output wires. To bypass this ballast, please cut all 6 wires. 2. Then, You can connect the two red wires to the black wire. 3. Next, please connect the two blue wires to the white wire. 4. For multiple bulb fixtures, just repeat the above steps on the other ballasts.
