I have a hanging, pull-string electrical light in my attic. This is very standard stuff. I would like to purchase an electrical device that will screw into the electric light and give me an electrical outlet. Think of this as a device with the base of an electric light bulb and an electical outlet instead of the bulb. I thought I saw one in a hardware store 20 years ago, but I have no idea if this product still exists. I can not think of what it would be called with a technical name when searching for one on the Internet.My business application is to be able to plug equipment into my attic rather than running the cord into the main house.
Go to Lowes, Home Depot, or any local Ace Hardware and tell them what you have written here. They are still available. Oh yeah, it's called a socket adapter.
It's called a light socket adapter. There are many places that sell them. Take care not to overload the low-current lighting circuit though !
Electrical circuits in domestic homes normally have two types of circuits. One for the lighting and another for the power supply. You are not supposed to use the lighting circuit for power supply. If you do you may be in contradiction of local wiring rules. As a result if there are any unfortunate events occurring as a consequence you will probably not be covered by insurance. In other words, if you burn your house down from using the lighting circuit for power supply you have no comeback. Having said all this it is unlikely to happen. Lighting circuits have a lower amperage rating and smaller wiring cross section. So therefore they cannot handle too much load, you may find annoying fuse blows or circuit breaker trips. In conclusion, and as an electrician, I recommend you just have a power supply correctly installed. It isn't as expensive as most people think.
