Great deal on a quality product. I used these tombstones to replace a 4 bulb shop light with T8 LED bulbs. For single sided LED lights you need these tombstones without a shunt. With LED lamps, the ballast must be removed. You simply load each side of the tombstone (see photos) hot and neutral (black and white). Then you can connect them in series. It was very easy. I used an extra wire from the ballast that I removed. This was the type I needed to put back in place in the store. All power cables are on one side and nothing is connected on the other side of the LED lamp. They are only needed to hold the lightbulb in place. They were just the size I needed and they all worked great. There are no problems with this product.
