These are great for adding a bit of light to anywhere there is a socket. I wanted to use my to test smart bulbs in different locations around my house and these are perfect.They do a Edison screw version, which I would recommend if you want to use it with a smart bulb as those types of bulbs can be heavy and coupled well a converter would lead to them drooping!Lovely product and work really well. Also much cheaper than some lamps out these days!
