Survey before you drill
A commercial logo 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
Mounting height and bracket choice
Aim for a straight-on shot and a reachable position. The geometry matters more than people expect: at 30 degrees off-axis a rectangular logo becomes visibly trapezoidal, and no amount of focus adjustment fixes it. If the only available position is steeply angled, plan the artwork to suit — or move the surface.
- 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
Aiming, zooming and focusing
Focus on the centre, then check the edges. A commercial logo 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.
- 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
Power, cable routing and switching
Fit the cable gland the right way up and leave a drip loop. Those two details prevent most of the water ingress calls on outdoor commercial logo projector installs. Then confirm the supply is switched and labelled, so the site team can isolate the unit without hunting through a distribution board.
- 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 a commercial logo 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
Handover notes worth leaving behind
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.
