Have had several in ground, in landscape beds, well lights that eventually need a new bulb after a few years of use. Cannot get to the bulb as all of the philips-head screws become frozen in place and cannot get the screws out to replace the bulb. Have tried several methods (sprays,drills etc.) to free up screws but eventually the screw is damaged and still stuck in place. looking for ideas to prevent screws from freezing in place so I can remove them down the road to change bulb when needed. Should I spray screws with something, or put grease or vaseline in screw hole. I am trying Volt well lights for the first time and they provide a hex key wrench to use for the screws. Not sure if that is a remedy. Suggestions welcome.
VOLT Conductive Grease is ideal for this purpose. It's the same type of grease that mechanics use for car battery terminals to prevent corrosion and frozen threads. Use a tiny amount on the tip of your finger to lubricate the threads. Since it's conductive, you don't want globs of it on the back of the bulb.
