@ship "changing a lamp on a live circuit"Neutral wire to front as per best practice.... If you could have a P-28s where either the neutral wire or the hot wire would be towards the front of the fixture accessible during lamp change... Just for the chance that a live hot conductor is compromised, and someone is it matters. Neutral wire to the front if not, should be a rule in splitting hairs but defined rational.

Yes, the lamp socket will wear out. And from the sound of it, yours have. Inside the socket there is a spring (which is what you press down when inserting the lamp) and it sounds like it is worn out, so it isn't able to press the lamp upward and make the connection. It is a very simple and fairly cheap process to change the lamp base.

This reminded me of a story my TD used tell in my college days. He was on a ladder and was changing a lamp in a leko. The dimmer was down but the burn base was still plugged in. Some T20s in those days had a metal collar that extended up from the lamp base. He grabbed the lamp to push in and twist. His hand came in contact with the collar and he found he could not let go. He had to yell for someone to kill the circuit. The story was enough for me to remember to unplug a fixture before any servicing.But anyone who tries to insert a 500w T20 lamp into a hot socket doesn't belong in this biz.
