What to check on the first visit
an indoor outdoor gobo projector install is mostly survey work. Walk the site at the hour the projection will run, because the ambient light, the position of vehicles, and even the position of a display stand all change what works. Take a photo, measure the throw, and mark the cable route before ordering anything.
- Power within reach of the mounting point
- What the target surface is made of and how it is lit
- Whether the mounting point carries the weight
- Access for future servicing — ladder or powered platform
Getting the geometry right before it is fixed
Choose the bracket before the fixture. an indoor outdoor gobo projector needs to hold its aim through thermal cycles and, outdoors, through wind loading; a lightweight bracket that drifts a degree will put the image off-target within a month. Use a bracket rated above the fixture weight, and if the install is exposed, check the fixings are stainless.
Aiming, zooming and focusing
Focus on the centre, then check the edges. an indoor outdoor gobo projector focused on a flat wall should read evenly corner to corner; if it does not, the usual cause is an angled mount rather than a bad lens. Once you are happy, lock the focus if the unit allows it, because vibration and thermal cycling will otherwise move it over a season.
- Set the bracket position first
- Zoom to frame the image on the surface
- Focus at the centre, then check all four corners
- Lock the focus if the unit allows it
Power, cable routing and switching
Power is where commercial installs fail inspection. an indoor outdoor gobo projector drawing 30–200 W is not a problem in itself, but a cable run across a public area, a domestic extension lead, or an unswitched spur all are. Plan a fixed supply, use a gland rated to the environment, and route the cable so it is neither a trip hazard nor the first thing a cleaner unplugs.
- Fixed, switched, protected supply
- Cable gland rated for the environment, fitted with a drip loop
- Run out of reach and out of the cleaning route
- Connection point accessible without dismantling the unit
Commissioning checks
Commission in three checks: image sharpness at the corners, contrast against the surface at the working hour, and a full duty cycle run without thermal cut-out. That last one matters for IP65 units in enclosed spaces, where an indoor outdoor gobo projector can pass every optical test and still trip after four hours in a hot ceiling void.
- Image sharpness at the centre and all four corners
- Contrast against the surface at the working hour
- Full duty cycle run without thermal cut-out
- Housing temperature after an hour at full output
What the site team needs on paper
The handover note should include the artwork file reference and the supplier's reorder code. Custom gobos are the one part of an indoor outdoor gobo projector install that cannot be improvised on site, and re-cutting from the original file is far cheaper than redrawing it.
