Understanding LED Screen Brightness: Lumens vs Nits
                     Understanding LED 
Screen Brightness
Nits vs Lumens Guide
The Brightness Confusion
Common Challenge Confusing Terms
Purchasing LED screens for Nits and Lumens both 
stores, stadiums, events measure brightness 
differently
Key Question
Which measurement should you prioritise?
What Are Nits?
Definition Formula
Measure of luminance - 1 nit = 1 cd/m²
light generated by source
Practical Use
Brightness you see on LED screens directly
From Latin "Nitere" meaning "to shine"
What Are Lumens?
Luminous Flux Common Uses
Amount of light emitted by Bulbs, projectors, lighting 
screen systems
Light Distribution
Spreads light across surface or view
Key Differences
Aspect Nits Lumens
Measures Luminance (brightness perceived) Luminous flux (total light output)
What They Measure Emitters of Light Distributors of Light
Standard Use LEDs, LCDs, OLEDs Projectors, bulbs
Viewing Direct viewing Projected/reflected light
Mathematical relationship: 1 nit = 3.426 lumens
Why Nits Matter for LED Screens
Viewing Comfort
Energy Efficiency
Prevent glare and eye strain
Visibility & Readability
Higher nits = more power 
Adjustable brightness for 
Overcome ambient light consumption
different conditions
Outdoor screens: 5,000-10,000+ nits LED tech reduces costs vs 
traditional lighting
Choosing the Right LED Screen
Content Type
Match LED to content needs
• Text vs video requirements
Environment
• Contrast vs brightness priority
Measure ambient light conditions • Corporate vs entertainment use
• Time of day considerations
Brightness Control
• Viewing distances and angles
• Natural light changes Essential for optimal performance
• Ambient light sensors
• Manual control options
• Energy efficiency benefits
Final Takeaway
Lumens Nits
For projectors and light distributors For LED screens and light emitters
Choose nits for LED screens - they measure direct brightness for optimal visibility
