I bought two of these to convert two polished long nose PAR64 cans into profile spots for a very small stage using LED filament lamps. Fitting was really easy. They are provided earthed, so the old earthing could be dispensed with. There is room between reflector and grill for quite large bulbs but the focus of the reflector is quite far back, so I have used golfball LED filament bulbs. Other bulbs I tried had the light source too far forward to be captured by the reflector and reflected forward. A Powercon fitted on the end of the cable without any further stripping or modification.
