***This Is Not a Plug-and-Play Type***: Disconnect the ballast and rewire the hot wire to one end of your fixture, and the neutral wire to the other end. If your fixture has been previously rewired for LED, please verify whether it's been set up for single-ended input LED tubes. If this is the case, you'll need to modify it to a double-ended wire setting, as plugging a double-ended input LED tube into a single-ended powered fixture will result in an electric shock. You can find the installation manual attached as the 2nd photo in the top left corner of this product page. We strongly recommend reviewing it before making a purchase.
***Must not work at 277V AC***: Check your voltage supply before buying, otherwise the bulb will be damaged quickly.
