I have an old floor lamp that I converted from halogen to LED. It has a dimmer knob but even when off it didn't turn off the light it was very faint. I thought it was the potentiometer/knob leaking current. I think I also had the issue on a room that also had a dimmer switch, an actual light in the ceiling not a lamp. So it seems to be the dimmer feature that is the issue for me.
