I have an Ott Floor lamp that hubby and I share. I use it behind my recliner when hand sewing. He uses it at the kitchen table while working on tiny things--electronic gizmos mostly. It has the flexible arms on it with a clip & magnifier. I also have a cheapy, clamp on light with a CFL bulb clamped onto my sewing table that I use at night and rainy days. I move it & clamp it on my cutting table when needed also.
I used to drag the Ott Lamp up & down the stairs but discovered my cheap, clip on works for what I do in my sewing room without dragging the bigger, expensive one around.
