I purchased this a while ago but I have to say I'm quite disappointed with it. I purchased with the 'warm' light but although it lights up the top of the music sheets, it does not light up the whole sheet on the sides, nor down to the bottom of the sheet, even if you manipulate it - it has limited
ovement. Also, there is a metal piece under the lamp that juts out a little over the music, so when you turn any music pages, the top catches on the metal, hence you have to keep 'freeing' them.
I knew it only worked via a socket, but have found this to be quite restricting as the lead isn't very long, as mentioned by previous customers. And yes, the lamp does get extremely hot. Perhaps the 'white' lamp would work better but I wouln't really recommend this lamp.
