Power-Saving Tips
Smart Brightness Scheduling
Reduce brightness during low-traffic hours. Saves 30-50% on electricity.
Ambient Light Sensors
Auto-dim based on room lighting conditions.
Content Optimization
Dark-themed content consumes significantly less power.
Scheduled Power-Off
Turn off displays during non-business hours.
Frequently Asked Questions
A typical indoor P2.5 LED display consumes 130-360 W/sqm (average to maximum). A 10 sqm display running 12 hours daily costs approximately AED 115/month in the UAE.
Maximum power is drawn when all LEDs display full white at full brightness. Average power (typically 30-40% of max) represents real-world content.
Yes, LED displays convert approximately 60-70% of electrical input into heat. A 10 sqm indoor display can generate 4,500-12,000 BTU/h of heat.
Circuit breaker sizing should be based on maximum power draw plus a 25% safety margin. Always consult a licensed electrician.
