How to Estimate LED Watts from Lumens
Estimating LED wattage from lumens helps compare with old incandescent bulbs. Modern LEDs produce approximately 80 lumens per watt.
To estimate LED watts, divide lumens by 80. For example, 800 lumens / 80 = 10 watts. This is an approximation; actual efficiency varies by LED quality (70-100 lm/W typical).
For reference, 800 lumens is equivalent to a traditional 60W incandescent bulb.
Quick Tips
- 1 mile = 1.609 km (miles are bigger)
- 1 kg = 2.205 lbs (roughly double + 10%)
- Temperature: (°F - 32) × 5/9 = °C
Frequently Asked Questions
Approximately 10 watts for a typical LED.
About 800 lumens.
No, they range from 70-100+ lumens per watt.
Always buy by lumens (brightness), not watts (power consumption).
