I bought a couple incandescent light bulbs. One of the small bulbs in the fridge went out and since it was a physically smaller bulb, there wasn't a ready replacement in the big box o' bulbs in the basement from when we converted to CFL. Given the size requirement and environment, a switch to CFL wasn't an option. So a direct replacement was bought and made. I think it's also been over a year since I changed any bulb.
