It's a replacement for a general 20W desklight
The flexibel uppper part makes it very mobile.
The disadvantage against the standard desklight is the powerbutton
At the standard light this button is posed onto the platform and therefor easier to handle.
with the powerbutton integrated into the platform you will have a double as long powerwire and so suitable for your low powercontacts in the wall.
The led desklight can only, for my case, be plugged into a contactbox on my desk.
