Electrical — Lighting
Replace spotlights without redoing the ceiling.
Power-hungry halogens, spotlights that have failed, light that has turned yellow or a model no longer made: in most cases the replacement goes into the existing hole. One still has to find the right diameter, and check what supplies them.
Aim
Keep the existing cut-outs
Saving
A 50 W halogen becomes 5 W in LED
