I have some 12-volt outdoor lighting that is quickly blowing through light bulbs (couple weeks at a time.) I just measured the voltage and it read 13.4 volts. Could this be the culprit?
The other potential issue could be that the bulbs are running too hot for the enclosure. This used to be a 120-volt system, but we had some landscaping lighting work done and they decided to convert it to a 12-volt system. The problem is that the sockets are still standard home style sockets and the only light bulbs that are easy to find are 50-watt marine light bulbs.
What is more likely the blame for the short light bulb life?
I'm looking into purchasing some 12-volt led lights from Amazon but I'd like to solve this problem before spending more money on bulbs.
