Wall-mounted lamp problem -- more support needed
Last year an electrician installed wall-mounted lamps over my bed. Each was installed in a junction box, but has no other support. The electrician claimed drywall would shore them up, but no such luck. I've never been able to swing the lamps out on their arms as intended because of sagging, and now even with the arms retracted, one lamp is visibly pulling away from the wall. What can I do to fix this?
