Fluorescent conversion to LED

I’m converting a fluorescent fixture to LED. Bought the Ty B double ended bulbs and have removed the ballast. I wired the hot to one side and the neutral to the other. The LED bulbs won’t turn on. I’ve tested voltage with a non-contact tester and there’s power at the hot end. When I put the LED bulb in, the power runs down the bulb but stops just before the neutral tombstone. If I flip the bulb, the same thing happens. Do I have bad bulbs or have I done something wrong? My hot side of the tombstone had two wires per tombstone. The instructions said if there were two wires coming from the lamp holder that these two wires should be wired or shunted together so I connected all four (two bulbs) wires together to the hot wire. submitted by /u/jabber_25 [link] [comments]
