LED vs Traditional Lighting
Efficiency Comparison
Compare LightsLighting technology has evolved dramatically. LEDs now produce the same light as incandescent bulbs using 75-85% less energy. Understanding efficiency helps you choose wisely.
Equivalent Bulb Wattages
| Light Output | Incandescent | CFL | LED |
|---|---|---|---|
| 450 lm | 40W | 9-11W | 4-5W |
| 800 lm | 60W | 13-15W | 8-10W |
| 1100 lm | 75W | 18-20W | 11-13W |
| 1600 lm | 100W | 23-25W | 15-18W |
Conclusion
LEDs are 5-10× more efficient than incandescent and last 25-50× longer. Despite higher upfront cost, LEDs save money over their lifetime through reduced energy use and replacement costs. For equivalent brightness, compare lumens, not watts.
