Dimmable
Wattage (W)
Claimed wattage. Our measurements indicate this is a reliable figure.
enter value/s in increments of i between 8 and 14
Initial luminosity score
Based on the light output of the lamp after 100 hours burn-in. The closer to its claimed lumens, the better. The best scoring models exceed their claims.
enter value/s in increments of i between 70 and 80
13800 hr luminosity score
Based on the light output after 13,800 hours' operation (about seven and a half years at five hours/day). The closer to its claimed lumens, the better. The best scoring models exceed their claims.

Measured light output after 13800 hrs (lm)
Measured light output after 13,800 hours, in lumens.
enter value/s in increments of i between 0 and 1115
Efficiency at 13800 hrs (lm/W)
Efficiency at 13,800 hours, in lumens per watt (lm/W). The higher the better (more light output for less energy usage).
