The Edison Screw (ES) was designed by Thomas Edison and licensed in 1909 under the MAZDA trademark and displaced other socket types for general lighting in the early days of electrification in North America and Continential Europe.
As Edison screws were the only standard connector appliances other than bulbs were connected to mains electricity via the light socket!

FAQS - These are some of the frequent questions we are asked about our ranges of lamp holders
Q) Which bulb should I use for my lamp holder
Q) I have purchased a 10mm threaded lamp holder but it will not fit the 10mm thread on my light fitting
A) All our lamp holders are a metric thread so if this does not fit you may have an Imperial thread.
Q) My lamp holder starts to come loose when I remove my light bulb, how can I stop this from happening?
A) If your lamp holder has a locking nut (we will include this information in the item description) tighten the locking nut and this will resolve this issue. If your lamp holder does not have a locking nut screw a nut on to the threaded rod and then screw your lamp holder down tight to the nut, when you next need to remove your light bulb the lamp holder will remain firmly in place
Q) I have locked my Edison Screw lamp holder how do I unlock it?
A) We have produced a video showing how to release your lamp holder https://www.youtube.com/watch?v=Nwf4xBuR4Zw
