Start with the throw distance
The first number to fix is the throw. A commercial logo projector rated for 6–30 m covers a very different wall at the near end than at the far end, and the image width roughly triples across that range on a typical zoom lens. Measure from the realistic mounting point — the one the site will actually let you use — and write it down before you look at any product page.
Match output to the ambient light
The wattage question is really an ambient light question. Daylight starts around 10,000 lux, a lit retail interior runs 300–500 lux, and a dim restaurant may sit under 100 lux. A commercial logo projector has to beat whatever is already falling on that surface, which is why the same model can look brilliant in a hotel portico and invisible in a shopping mall concourse.

Lens, zoom and focus
Zoom and focus are the two adjustments you will use ten times and the ones cheap units make hardest. A zoom range lets one commercial logo projector cover several mounting positions, which matters when the final bracket location is decided on site rather than on paper. Look for a lens that holds focus across the zoom travel, because a unit that has to be re-focused every time you zoom is a unit that will be left slightly out of focus.
What your artwork forces you to buy
Choose the gobo from the artwork file. Solid block logos survive etching into stainless steel and will outlast the projector, but anything with hairlines, grey levels or a photographic element has to go on glass. This is the decision that most often gets made backwards — the buyer orders a cheap metal gobo, sees the result on the wall, and reorders in glass two weeks later.
Ingress rating and mounting environment
Match the rating to the site honestly. A commercial logo projector mounted under a canopy needs far less protection than one on an open facade, and the price difference across ratings is real. What catches people out is the cable entry — a housing can be rated IP65 while the gland supplied with it is not, and that is where water actually gets in.
- Is the position exposed to driving rain or only wind-blown moisture
- Whether the cable gland is rated with the housing
- UV exposure on painted finishes and plastic parts
- Salt or pollutant load in the air
The five lines that get an accurate quote
The fastest quotes come from the most specific enquiries. Include the mounting height, the distance to the target surface, whether it is indoor or exposed, and the artwork in vector if you have it. A commercial logo projector specification built from those details can be quoted and shipped without a second round of clarification.

- Image size needed
- Indoor or exposed position
