If your lamp is the type that requires a tombstone with a latch ----- That's the ticket. They snap right into place, holding your new LED tubes securely. Recently 7 lights were switched to LED headstones "non-ranging". 4 out of my 7 were "click" style, not slide style. Thanks to them, the transition from phosphor to LED was a "click" (the correct word would be "click", but...). You press the tab that the pin is pointing at and these tombstones snap into your mount.
