I bought this to clip onto my headboard but the clamp is so strong you can't open it up far enough to clip onto the headboard. I'll end up using it on my computer desk because it's not as thick so the clamp will hold just fine. I plugged the cord into a socket adapter, so keep that in mind when you buy this lamp. It gives off plenty of light and you can adjust the hew (I prefer the bright white mode, so I don't think you'll have to worry about having enough light for your needs. The price is right also, and the goose neck allows the light to go just about any place you need it.
