Logo projectors: a buyer guide

A logo projector, also called a gobo projector, uses optics and a physical image insert to place a mark or design onto a wall, floor, ceiling or other surface. The useful question is whether the image remains the right size, focus, contrast and position in the actual space.

Start with the image and surface

Record the artwork, projected image width, target surface, viewing distance and whether the image is static or needs to change. Surface colour, texture, angle and reflectivity affect the result, so a white wall, dark floor, glass frontage and rough architectural surface should not be treated as interchangeable.

Check the optical brief

• ✓Supply artwork that can be reviewed for the selected gobo or image-production process.
• ✓Measure the lens-to-surface distance and intended image width.
• ✓Confirm focus range, lens or optical geometry and the mounting position.
• ✓Record whether the image must be sharp at one plane or remain readable across an uneven surface.
• ✓Check the documented light output in the intended operating mode against the room's competing light.

Match the projector to the environment

Indoor and outdoor installations can have different requirements for dust, moisture, temperature, mounting, power, access and operating hours. Confirm the selected model's documented environmental rating and installation limits; do not infer outdoor suitability from a marketing description.

Treat content rights as part of the brief

• Confirm permission to use the logo, photograph, illustration or message.
• Confirm venue approval for the projection surface, mounting position and operating schedule.
• Keep source artwork, approved output and installation notes together so later changes can be checked.
• Avoid claiming visibility, lifespan, maintenance savings or marketing impact without model- and site-specific evidence.

Next action

Send the artwork, target surface photo, desired image width, approximate distance, ambient-light notes, operating hours and indoor/outdoor location. The project team can then determine what needs to be measured before a model or quotation is recommended.
