Acrylic and lamp base compatibility is more than a nominal slot-width question. The panel must enter the slot consistently, remain stable at its final height and carry light through the intended lower edge.

Measure the finished panel, not only the raw sheet

State the actual lower-edge thickness after printing, protective film, polishing, coating or any attached layer is considered. If the plate has tabs, stepped edges or a shaped lower section, send a dimensioned drawing. A single “3 mm acrylic” description may not define the part that enters the base.

Confirm insertion depth and lower-edge geometry

The illuminated edge should sit where the LEDs can feed light into the panel. Too little insertion may reduce stability or create an uneven light line. Excessive insertion may hide artwork or interfere with internal parts. Mark the intended visible line and the portion that may enter the base.

Check height, weight and center of gravity

A tall or wide panel creates more leverage than a small name plate. Share the overall dimensions, weight and orientation so the base footprint and slot engagement can be reviewed together. Freestanding stability should be checked with the final panel rather than inferred from a smaller sample.

Prepare the light-entry edge

Laser engraving, printed graphics and surface treatment can change the way the panel appears. Identify the light-entry edge, viewing direction and any opaque printed area. The sample should use representative artwork so brightness and visual balance are evaluated on the intended design.

Panel compatibility checklist

  • Finished lower-edge thickness and tolerance
  • Insertion depth and visible artwork boundary
  • Overall width, height, weight and orientation
  • Light-entry edge finish and engraving or print method
  • Required cable exit, switch access and display direction

Choose a starting base

A round ABS platform such as the classic round acrylic lamp base is a practical reference for common flat inserts. The slim round base, square base and wood alternatives create different footprints and presentations. Compare the published standard models before requesting a different slot or housing.

Best practice: approve the lamp base and its final acrylic insert as one sample set. A base-only electrical test does not confirm panel fit, stability or finished artwork appearance.
