Is It Safe to Leave a Light Bulb Socket Empty?

Spread the love

It has all happened to us before — we burn out one of our light bulbs and do not have any fresh ones in our pantry. Well, what should we do leave the burnt-out light bulb in place or just take it out leaving the socket with no light bulb in it? Is it safe to leave a light bulb socket empty? That is a good question, so let’s discuss it further.

Safety is a concern and that means to answer this question fully we should understand what happens to the electric flow when there is nothing closing the circuit.

Does an Empty Socket Use Energy?

The simple answer is no in most cases because in order to keep the current flowing the circuit must be closed. So, if there is no light bulb to close that circuit, there is technically no energy transferal. Now that being said, if something or someone is inserted in the empty socket that can close the circuit, it becomes a safety issue for sure. Now on the rare occasion that the socket is designed with a parallel to the circuit, then this will give you a short circuit. This style of light fixture will allow the flow of energy to continue and can cause overheating and melting of wires if there is nothing in them to dissipate all of that.

Basically, if you have no outlet for all of the energy and that is conducted through the circuit, all of that energy and heat needs to go somewhere and the logical place for it to go is either back to where it came from or become heat energy within the wires. If the energy heads back to its source, your home is set up for that with the breaker box. However, if the energy decides to chill and become heat, this is when an empty socket becomes a safety issue.  

That sounds dangerous, right? So, going back to our original question…

Is it Safe to Leave a Light Bulb Socket Empty?

If there is no energy going through the socket, then why do we need to worry about it? Well, there are many things that could create some problems for you. For instance, if your light fixture is a lamp you may want to reconsider leaving it empty especially if you have young kids around the house. Yes, there is technically no energy flowing through that socket currently, but those little ones are very curious. All it would take is for them to decide to see what happens when fork meets socket and then you will be taking an unexpected trip to the emergency room.

It doesn’t even take a precocious toddler to create a spark. It could be as simple as dust, lint or even a bug encountering the unclosed circuit that sparks the circuit and a fire. So, no it is not safe to leave you light bulb socket empty. There are many solutions to this… you can simply leave the burnt-out light bulb in the socket or check out some of the ideas below.

Creative Solutions for an Empty Socket

As we said above, you can just leave the burnt-out bulb in its socket or here are some ways to make sure your sockets aren’t left empty and ready to be a safety hazard:

  • Use a socket base plug or a safety cap, both of which should be available at any hardware or home store.
  • There is an old-school screw-in plug that converts your socket to a 2-wire cord socket that might be able to be found at hardware stores
  • Rubber crutch tips can be used to insert into the empty socket.

The best way to make sure your socket isn’t left empty is to simply replace the light bulb.

Final Words

So, is it safe to leave your light socket empty? The choice is yours but rather than worrying about what people may think if you have a burnt-out light bulb, perhaps the simplest solution is to just leave the socket full and get a replacement bulb as soon as possible. For safety reasons, it is advisable to not leave that socket empty. It is a safety hazard for small children (and maybe some adults) as well as a fire hazard. Now that you are armed with this information, you can keep your home and family and friends safe by never leaving another light socket empty.
