Color Temperature Color temperature is the color of the light that is emitted by a lamp. It is measured in Kelvin (K) and ranges from about 1000 to 10000. A temperature of 1000 is warm candle-like light, 10000 is cold blue-like light. For normal house lighting a temperature around 2700K is advised.
2700 K (Extra warm white)
Lumen Lumen is the amount of light that is produced by a lamp. Different types of lamps (incandescent, CFL, halogen, LED) need a different amount of energy to produce the same amount of light. However there are always other factors which influence the exact amount and direction of light. Despite differences in energy consumption, the amount of lumen is the same for different types of lamps and therefore they should produce the same amount of light.
CRI / Ra CRI / Ra is the Color Rendering Index, measured in Ra. It defines the quality of light when seen by the human eye. The CRI / Ra provides information about how real colors appear under certain light circumstances. The CRI scales from 0 to 100 where 100 is the best possible light quality.
Watt Actual power consumption in Watts consumed by the lamp
Watt Comparable: Power consumption for same amount of light (Lumen) as produced by an incandescent lamp
Switches Number of times a lamp can be switched on and off without breaking down.
