What is important to you?
Can you change the lightbulb?
If you want to use a smart lightbulb, it must be possible for you to replace the lightbulb and have the appropriate base.
Where does the clamp lamp get its power from?
Some clamp lamps use a rechargeable battery and therefore can be used without cables and placed anywhere.
However, many clamp lights have to be connected to a socket. This limits the scope due to the length of the cable.
Is the light dimmable?
Some clamp lights have a touch-dimmer function. However, if you would like to be able to dim your lamp via a remote control or an app, you should change the light source to a smart lightbulb to add this function.
