Recessed HI-Spot 120 spotlights in a false ceiling

A false ceiling allows lighting with large caliber recessed spots, using Hi-Spot 120 mm halogen bulbs. Unlike the small spots in the lighting is often only punctual, they allow a powerful lighting at 30°. The metal frame of the claw spot must be connected to earth.

Necessary material

  • Stool
  • Drill
  • Junction box
  • Electric cable
  • spots
  • Cutter
  • Counter Saw
  • Screwdriver
  • Compass
  • Anchors
  • Screw

Steps

  1. Cutting the slab into the false ceiling

Cutting the slab into the false ceiling

Electrical connection

Electrical connection

1. The projectors are powered here by multicore cables that run in the false ceiling. You can use watertight junction boxes with a more comfortable volume for connections. Screw them to the ceiling itself. Make the connections. Do not forget the ground wire.

Measure the diameter of the metal frame of the spot

2. Recessed light spots for this type of bulb include a metal frame with a flange that is pressed against the false ceiling. Take the dimension of the internal diameter of this flange: it determines the diameter of the hole to be drilled in the insulating slab to allow the setting up of the spot itself. Trace the piercing line with a compass.

Cut the slab for the passage of the spot

3. Cut out the ceiling tile with a window saw. Start by drilling a hole inside the cutting circle with a cutter or with a drill bit on a drill to introduce the saw blade; take a saw with fine teeth.

Passage of the electrical cable of the spot in the slab

Passage of the electrical cable of the spot in the slab

1. Place the cut slab and the adjacent slabs. Pass the power cable through the hole, and connect the spot board to the electrical conductors by carefully tightening the screws with a suitable screwdriver. A bad contact poses a problem of repair more important than in the case of a simple bulb. The electric cable must be a little loose to avoid any difficulty in setting up the light spot.

Fixing the electric cable

2. The frame of the spot includes a metal bracket and a retaining bracket for the electric cable. Secure the cable to prevent the wires from being pulled out and to simplify positioning of the spot itself.

Adjusting the fins

3. The spot here rests on the slab via a system of adjustable fins. Sometimes it is fixed by claws. Move these fins closer to slide the frame into the ceiling through the hole. Then the fins are placed on the notch. Screw the Hi-Spot 120 bulb of the spot.
