GWI ring lights in various configurations

Illuminate Every Angle with Uniform LED Ring Light Technology

The GWI LED Ring Lights provide bright, uniform illumination that surrounds your vision camera for improved image quality and reliable inspection performance. Designed for industrial machine vision applications, these lights are built to complement vision systems by reducing shadows and delivering consistent lighting across your field of view.

Lighting quality is crucial to machine vision performance. Ring lights provide even, direct illumination that wraps around the viewing area, helping your cameras capture clearer, higher-contrast images when inspecting textures, colors, and reflective surfaces. The reduction of shadows and hot spots directly improves inspection repeatability and accuracy.

Available in multiple sizes and configurations, including the GWI 4 Eye, 4 inch remote phosphor ring light, 3 inch ring light, and 4 inch ring light, GWI offers flexibility in color spectrum, form factor, and mounting flexibility to match your application requirements.
