We had a lamp at home that was difficult to replace. There was nothing quite like it at Lowes or Home Depot and we didn't want to spend a fortune. We considered just swapping it out, but it fit the space perfectly and we decided to keep it. The problem was that the contacts were corroded and the wires were in terrible condition due to the excessive heat from the incandescent bulbs that had been used in the fixture for over 60 years. We replaced the lightbulb with an LED, but the damage was already done. These cartridges exactly matched the socket used in the lamp. I found a suitable heat resistant wire to replace the old wires, made the replacement in minutes and the unit was like new. Much safer than before. It was an inexpensive solution compared to a new fixture.
