Vector Floor-to-Ceiling Lamp

About 20 minutes, one screw in the ceiling, no electrician. Read the whole page once before you drill.

Requires a ceiling height of 8 ft 6 in to 11 ft 6 in (102 to 138 in). Measure first.

Before you start

In the box

  • Base cone with power cord and plug. A hex set screw sits at its collar.
  • Three light cones, fixed on the cable. They do not slide.
  • Ceiling fitting with a push-button cable lock and a side exit slot.
  • 2 yellow expansion anchors and 2 silver screws, for concrete or masonry.
  • 1 black coarse-thread screw, for a wood joist or a drywall anchor.
  • Hex key for the base set screw.

You need

  • Step ladder, pencil, tape measure.
  • Electric drill/driver with a long Phillips bit. The bit has to reach up through the open bottom of the fitting. A long screwdriver works if you drive by hand.
  • Concrete: hammer drill and a 1/4 in (6 mm) masonry bit.
  • Wood joist: a stud finder. No pilot hole needed with a driver; a 1/8 in pilot bit if you drive by hand.
  • Drywall with no joist: one ceiling-rated self-drilling drywall anchor (50 lb class) from the hardware store.

Do not plug in until the lamp is fully mounted.

01

Pick the spot

Decide where the base cone will stand. It is 4.7 in (120 mm) across and the cord has to reach an outlet. Mark the floor.

Find the point on the ceiling directly above the mark. Hang a weighted string from the ceiling, or use your phone’s level app held against the cable once it is up. Keep the ceiling point at least 3 in from any wall so the 3.1 in (80 mm) light cones clear it. Mark the ceiling.

02

Mount the ceiling fitting. Choose your ceiling.

The fitting is hollow. In every case the screw goes inside it, pokes out the top, and you drive it from below with a long Phillips screwdriver through the open bottom.

A Wood joist

Most US homes: drywall over wood joists.

  1. Find a joist with a stud finder. Joists run every 16 or 24 in. If your mark misses one, move the lamp a few inches rather than screwing into bare drywall.
  2. Drop the black screw into the fitting so it pokes out the top.
  3. Hold the fitting flat against the ceiling and drive the screw straight in with an electric driver, through the open bottom of the fitting. No pilot hole needed. Stop when snug; do not overtighten.
  4. Driving by hand? Drill a 1/8 in pilot hole at the mark first, then drive the screw with a long Phillips screwdriver.

B Concrete or masonry

Lofts, many apartments, garages.

  1. Hammer-drill a 1/4 in (6 mm) hole as deep as the anchor is long.
  2. Blow the dust out and tap a yellow anchor in flush.
  3. Drop a silver screw into the fitting so it pokes out the top.
  4. Hold the fitting to the ceiling and drive the screw into the anchor until snug.

C Drywall, no joist

Only if you cannot move the lamp to a joist.

  1. The included screws are not enough for hollow drywall with a straight-down pull.
  2. Install a ceiling-rated self-drilling drywall anchor (50 lb class) at the mark, following its packaging.
  3. Drive the anchor’s own screw, or the black screw if it fits, through the fitting into the anchor.

Feed the cable

Push the free end of the cable up into the bottom of the fitting until it comes out of the side slot. Press the button on the fitting while you push; the cable slides freely only while the button is down.

Set the cable length

Read this first. The three light cones are fixed on the cable, 61.4 in (1558.5 mm) from the top cone to the bottom cone. Only two things adjust: the cable above the top cone, at the ceiling fitting, and the cable below the bottom cone, which stores inside the base. Where the cones sit is set by how you split the spare cable between those two places.

  1. Stand the base cone on its floor mark. Press the fitting button and pull cable through until the base sits flat and the cable is lightly taut. Release the button to lock.
  2. Decide your split with the table below. On an 8 ft 6 in ceiling the top cone sits about 17 in below the ceiling and the bottom cone about 24 in above the floor.
  3. Store the excess in the base: loosen the base set screw with the hex key, press the fitting button, and pull the cable down from the base end until the loop at the ceiling is short. Feed the excess into the base and tighten the set screw.
  4. Final tension at the ceiling: press the button, pull the last inch through, release.

Plug in

Route the cord along the baseboard, plug in, switch on. The two upper cones light the floor and the lower cone lights the ceiling.

Why the cones are not evenly spaced

From the top: 19.7 in (500 mm) between the first and second cone, then 41.7 in (1058.5 mm) to the third. The first two face down, the third faces up.

That is deliberate. Each cone hides its light source from the one below it, so you never look straight into a lens from a sofa or a bed, and the light lands on the floor and the ceiling instead of in your eyes. Equal spacing would put one cone at seated eye level on almost every ceiling height.

The spacing is built into the cable and cannot be changed. Requires a ceiling height of 8 ft 6 in to 11 ft 6 in (102 to 138 in).

Troubleshooting

The cones sit close to the ceiling

Your ceiling is under 8 ft 6 in. The lamp is installed correctly; the fixed cone span just takes up more of the height. On a 96 in ceiling expect the top cone about 14 in below the ceiling and the bottom cone about 21 in above the floor. Give the top a little more cable than the bottom if you prefer the block lower.

There is a loop of cable hanging at the ceiling

That is spare cable. Loosen the base set screw, press the fitting button, pull the cable down from the base end, feed the excess into the base, tighten. Step 04.

The base rocks or the cable sags

Press the fitting button and take up another inch at the ceiling. The cable should be lightly taut, not tight.

The fitting pulled out of the ceiling

It was screwed into bare drywall. It needs a joist (case A) or a ceiling-rated drywall anchor (case C). Patch the hole and remount.

The cable will not slide through the fitting

Press the button fully and keep the cable straight in line with the fitting. Feed the end in from the bottom, not from the side slot.
