Are you referring to swing arm lamps that hang on the wall for the bedside? If so, then sit in the bed like you are goingh to read and the shade should come down maybe to shoulder height. In other words, the arc of light should be over your shoulder and reading area.

If only it were that simple-LOL!

We don't own the bed yet. We currently have a queen and are hoping to get a kind bed in the next year or so.

So now I have to guess where it should go for the electrician. He want to put it at 60" off the floor which seems really, really high. Maybe we should just give up on this idea and buy bedside table lamps.

They make adjustable swing-arm lamps. I have two of them.

Ours are set at about 60", and I remember specifying it--I think because I got my husband in bed :) and tried out various heights/placements, as it were...

That said, they're that high partly because they're within the width of the bed frame, above the somewhat high headboard. If you want them off to the side, say if you have a really high headboard and there's nowhere to put them within the width of the bedframe, and so you pull them over to focus on your reading, you can put them lower. I have seen that done too. Honestly I didn't want that because of the possibility to knock into it (if there's a possibility that I'll be clumsy, it's pretty much a given), so I wanted them to be far enough away I wouldn't hurt them or me if I forgot and got up out of bed. HTH.
