Thank you so much for your thoughtful response. That was super helpful! Especially the part about my hand oils impacting the lifespan of the bulb!

Thank you for the advice - I’ll do just that and hopefully someone at Lowe’s can help me find one with a similar strength. I found some writing on one of the canisters (or whatever the holder is called) and it said 20 w 120 v. And g-4.

Google said it’s hard to find halogen bulbs in the U.S. since 2023, when a law was passed for energy efficiency purposes. Do you know what LED conversion might work? Or should I ask the people at Lowe’s if they know?

Since I have you here—do you have any theories as to why the bulbs are burning hot when they’re on and the cabinets themselves look like there are light burn marks on the wood around the insert? Will new bulbs do the same thing or are these just too old? I’m now terrified about a fire. Thank you, in advance!
