Non-shunted Turn Type T8 Lamp Holder JACKYLED 20-Pack UL Socket Tombstone for LED Fluorescent Tube Replacements Medium Bi-pin Socket for Programmed Start Ballasts

GREAT HOLDERS, STURDY, EASY TO INSTALL, HEAVIER THAN ORIGINALS, GOOD PRICE. WILL BUY THESE AGAIN WHEN NEEDED.

Exact replacement that worked just fine.

tombstones were a great value and easy installation.

Turns out I won't be needing these after all, but I'm going to hang on to them in case any tombstones I already own break in the future. They are definitely un-shunted, and seem strong. I was able to screw a fluorescent tube into them without trouble. I gave four stars instead of five because as some other reviewers mentioned, they're a bit thicker and shorter than what's already in my fixtures, which could make using them as replacements for old worn tombstones a problem. The hardware store only seemed to sell them in packs of two at 3X the price, so I passed on theirs.

Great for replacing broken connectors

Perfect fit

Easy to install - push in connector. Easily replaced 4 tombstones on an old fluorescent shop light. Tested and they work fine.

Several months ago, we had 16 fluorescent bulbs in our kitchen dome ceiling. They worked when they wanted to. Bulb replacements were very expensive for tubes and ballasts that didn't last. After some research, we ordered the JACKLED tombstones to modify the light fixtures to use T8 LEDs. The majority of the T8 LED replacements are wired to have the +/- at one end as opposed to fluorescents that are wired positive at one end an negative at the other end of the tubes. To do this, non-shunted tombstones do not have internal bridges from side to side and are a must. If you did need them shunted, a bridge wire would make it possible. After stripping all of the wires and the ballasts out of the fixtures, it was simple to insert a 14 gauge house wire into the tombstone, reassemble the fixture, make certain that the proper end of the tube is powered, and enjoy the new LEDs. Converting T8 flourescent fixtures to LED is cheaper that buying new fixturesAmazon, as always, had the price, packaging, and delivery time.Even though we pre-wired all 16 tube locations, we only used 8 LEDs as opposed to the 16 fluorescents. In choosing LEDs, we opted for the daylight white and found that 8 LEDs gave more light than the 16 flourescents (when they did work). Because the LED T8s are wired at only one end, we attached a label on each fixture for future reference. Included on the label was the tube information should one ever have to be replaced.We have since sold the home and the LED conversions in the garage and kitchen were strong selling points. It was amazing to see the response of buyers whom had viewed other homes still using the flourescents. We are now converting the flourescent fixtures in our other home. We are also buying used fixtures to modify for the garage and basement.You can also buy the tombstones with a pigtail wire that are more expensive. But why go that route and use wire nuts to attach the wires when the house wiring can be inserted directly into the tombstone and wires are only needed at one end. Also, it is best to replace the tombstones at both ends of the fixture because there is a height factor between manufacturers.
