A total of five different measurements and calculated values were used to determine a numeric value for each bulb and dimmer combination (including different dimmer settings/curves/profiles available on some dimmer models). These bulb-dimmer interactions included:

The ideal score would be 100, however no bulb-dimmer combination scored this high. Bulbs performed differently with different dimmers & with different profiles (curves) of the same dimmer. Dimmers can alter bulb light output & efficiencies.
