Why a garage door needs a bright projector

Size is the problem. A typical single garage door is about 2.4 × 2.1 m (8 × 7 ft), roughly 5 square metres. A double is about 4.9 m (16 ft) wide, roughly 10 square metres. A window is closer to one. The projector's light is spread across that whole area, and it is competing with porch lights, coach lights beside the door and streetlights.

That is why small portables look faint here. The Nebula Capsule 3 Laser is the projector we use in our own videos, and we keep it for windows and props: spread across a double door, its 300 ANSI lumens works out to roughly a fourteenth of the light per square metre that the Horizon 20 Pro delivers. Battery projectors also tend to dim themselves when unplugged; Nebula's support page lists lower brightness figures for the Capsule on battery.

How many lumens for a garage door?

These are starting points for after full dark, with nearby lights switched off. Compare ANSI or ISO figures only. Cheap units that advertise five-digit lumen numbers with no standard attached cannot be compared with them.

• Pale single door on a dark street: about 3,000 lumens.
• Double door, a streetlight nearby, or a show that starts at dusk: 4,000 or more.
• Dark-painted or wooden door: 5,000 or more, or shrink the image to the area that matters.
• Whole house front: 4,000–5,000 or more for a pale single-storey front; brick, dark siding or two storeys need more, or a section at a time.

Throw distance: how far back to put the projector

Distance is roughly image width × throw ratio. With the Horizon 20 Pro at its widest setting (1.2:1), that is about 1.2 m back for every metre of width. Measure from the lens to the door and add room behind for the stand and cable.

One catch: a single garage door is nearly square, while a projector image is 16:9. Fill the door's width and the picture covers only about two-thirds of its height, which is fine for a face or ghost in the middle. To fill it top to bottom, size the image to the door's height and mask the extra width to black. A double door is wider than 16:9, so filling its width covers its full height. Our throw-distance calculator does the same sums for any projector.

• Single door, fill the width (2.4 m): about 2.9–3.6 m (10–12 ft) across the Horizon 20 Pro's zoom range.
• Single door, fill the full height (2.1 m): about 4.5–5.7 m (15–19 ft), with the sides masked.
• Double door (4.9 m): about 5.9–7.3 m (19–24 ft).
• Short-throw Optoma GT2000HDR: about 1.2 m (4 ft) for a single door's width, 2.4 m (8 ft) for a double.

Where to put it: yard, driveway or across the street

The driveway, centered on the door, is usually best. Set the lens at roughly the door's mid-height so the image lands square and the horizontal panel seams cast less shadow. Lens shift helps when the projector has to sit lower. Keep cars out of the driveway for the night and mark the stand's position so it goes back in the same place.

The yard, off to one side, works when trick-or-treaters need the driveway. The angle stretches the image, which a mapping app can correct, but the far side of the door ends up dimmer and softer, so keep the angle modest.

Across the street is a bad idea. It is a public road or a neighbor's property, cars and people cross the beam, and at 12–15 m even the Horizon's longest zoom setting (1.5:1) throws an image 8–10 m wide, so most of the light misses the door. Wherever you set up, keep the beam out of the path visitors walk, or raise the projector so they pass underneath.

Weather and power

None of the projectors here are weatherproof. Do not run them in rain, and keep them off wet grass on a table or sturdy stand. A canopy or patio umbrella with open sides keeps drizzle and dew off while leaving the vents clear. Never run a projector in a sealed box: it needs to exhaust heat. XGIMI rates the Horizon 20 Pro for 0–40°C (32–104°F), so check the forecast on cold nights.

Plan an outdoor-rated extension cord from a GFCI-protected outlet, with the connection off the ground and covered. Run the cord along the edge of the driveway, or under a cable cover where people walk. When you bring the projector in, let it warm to room temperature before switching it on again so any condensation can clear.

Content that reads from the street

People see a garage door from the sidewalk or across the road, often while walking. Big, slow, high-contrast scenes on pure black work best: one giant face, drifting fog, ghosts that cross the whole door. Fine detail and small text disappear at that distance, and fast motion turns to noise.

Switch off the coach lights beside the door and any porch light that falls on it, because they wash out the edges first. If the door has windows, mask them to black rather than projecting onto glass. And keep the light on the door: bright animation spilling toward the road distracts drivers on a night full of children.

Mapping the door from your phone

A plain video spills a rectangle of light past the door onto the wall and driveway. Projection mapping fits the scene to the door instead, so everything outside the door stays dark. The garage door section of Lazy Lighting's Halloween guide covers drawing one shape over the door and filling it with a scene; a sectional door can also be mapped panel by panel.

With a Google TV projector such as the Horizon 20 Pro, Lazy Lighting Link lets the phone stay indoors and send the show over Wi-Fi, as long as the signal reaches the driveway. Keep the phone on its charger and, on iPhone, set Auto-Lock to Never so it does not sleep mid-loop. For your own loops, start with Lazy Lighting's list of free Halloween projector videos.
