In the last 10 years I started stock pilling again after I realized that most old tech lamp stuff is getting rare, removed and not available anymore. I’m mainly after old classic Swiss streetlights and their parts which are now not existent anymore outside. For every lantern in stock I have at least a pair of lamp sockets, bowls, gaskets all the needed gears and other parts. Also very rare or hard to come by lamps like Powergrooves and other T12 tubes, rare incandescent lamps and many different kind of HID lamps I keep in stock as I’m going to use them one day.
I agree with that too, and I feel like I should hoard some of that as well.
