What to check on the first visit
A logo projector light 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.
- Nearest power and whether it is switched
- Surface material, colour and ambient light at the working hour
- Fixing substrate and bracket load
- How the unit will be reached for cleaning
Mounting height and bracket choice
Choose the bracket before the fixture. A logo projector light 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.
- Bracket rated above the fixture weight
- Stainless fixings for exposed positions
- Beam as close to perpendicular as the site allows
- Position reachable without powered access
The order of adjustments
Focus on the centre, then check the edges. A logo projector light 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.
- Confirm the geometry and tighten the bracket
- Zoom until the image fills the intended area
- Focus on the centre of the image
- Check the corners — soft corners mean an angled mount
The part that fails inspection, not the optics
Power is where commercial installs fail inspection. A logo projector light drawing 15–150 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
Test it the way it will be used
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 IP44 units in enclosed spaces, where a logo projector light 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
Leave four things behind: the throw distance and image width as installed, the gobo reference, the focus and zoom settings, and the supplier's contact for re-cutting artwork. Six months later, when somebody asks for a second unit to match, that sheet of paper is worth more than the manual.
