Brightness is measured in nits. A nit equals one candela per square meter. Typical indoor office screens run at 250 to 300 nits. Retail and hospitality require more because of reflections and overhead lighting.
Ideal Brightness by Environment

Recommended Brightness
Notes
Office or healthcare
250 to 350 nits
Balanced for eye comfort
Retail or lobby
400 to 500 nits
Handles bright lighting
Window facing
700 to 1000 nits
Cuts glare from daylight
Outdoor enclosed
1500 nits or more
Must add ventilation
Brightness must also account for surface finish. Glossy panels look richer but reflect light. Matte coatings reduce glare but slightly lower contrast.
Dynamic Brightness Control
ELOView supports brightness scheduling. Reduce intensity at night or during low-traffic hours. This extends LED life, lowers power use, and minimizes color drift.
Long-Term Impacts
Operating permanently at maximum brightness can shorten backlight life by up to 30 percent. Scheduling and ambient light sensors prevent overheating and save cost over time.
Final Thoughts
Match brightness to light levels, not perception. Balance clarity, comfort, and efficiency. When tuned correctly, an ELO display remains vivid for many years without fatigue or excessive power draw.
