Golf Simulator Lighting Setup: How to Avoid Glare and Tracking Errors
Lighting setup is one of the most overlooked factors in golf simulator accuracy. Learn how ambient light, directional sources, and light color temperature affect launch monitor performance.
How Different Launch Monitors Handle Light
Camera-based launch monitors photograph the ball and club at impact using high-speed cameras. Systems including SkyTrak, SkyTrak+, Garmin Approach R10, Uneekor QED, and Uneekor EYE XO are sensitive to light conditions because anything that affects camera exposure or introduces lens flare can degrade image quality at the moment of impact.
Radar-based systems like Trackman 4 and Foresight Sports GCQuad use Doppler radar or photometric measurement rather than cameras. Lighting has almost no effect on the accuracy of these systems, but it still matters for screen readability and player comfort.
What Lighting Problems Cause Tracking Errors
Directional spotlights aimed at the impact area are the most common cause of camera-based tracking errors. When a bright light source is in or near the camera field of view, it can overexpose frames and cause the system to miss the ball or produce inaccurate spin readings. This shows up as random zero-spin readings, missed shots, or ball speeds inconsistent with how the shot felt.
Flickering lighting is another problem. Standard fluorescent tubes and some LED fixtures not designed for camera use can flicker at 50 or 60 Hz, which is invisible to the human eye but visible to a high-speed camera. A flickering light source in the camera frame can cause periodic tracking failures even if the average light level is fine.
Recommended Lighting Setup
Use LED fixtures with a CRI (Color Rendering Index) of 90 or higher, rated for flicker-free operation. Mount lights on the ceiling at the sides of the room rather than directly above the impact area. Point them toward the ceiling or walls for indirect, diffused illumination rather than directing them at the hitting mat or screen.
For the impact zone specifically, avoid any light source that the launch monitor camera could see when aimed at the ball. Check your launch monitor field of view and keep all light sources outside that cone. Blackout curtains on any windows prevent sunlight from entering at different angles throughout the day.
