I have a table Ott light behind my sewing machine. It came with a weighted base or a screw to attach to the edge of a table. I use the base. I can adjust it up and around to shine on my design wall behind my table or up higher if I'm cutting. I've a floor Ott light over my ironing table. That one sits on a box to make it be high enough above the ironing board. I just bought a 25 w HD lamp to go in a lamp in my living room. It says it's to replace a 100 w bulb. It's not bright enough to read by, so that's going back to the store.
