Energy efficiency class: Rating of how efficiently a device uses energy, affecting power consumption and costs.
Equivalent bulb power: More energy-efficient light technologies often require less power than original bulb technology. The equivalent bulb power compares the power of a new bulb with the power for an original bulb to produce the same amount of light.
Bulb lifetime: The length of time that the bulb will last for.
Luminous flux: Luminous flux or luminous power is the measure of the perceived power of light measured in lumen. The luminous flux is a weighted sum of the power at all wavelengths in the visible band.
Fitting/cap type: The type of fitting (used in pipe plumbing systems to connect straight pipe or tubing sections, to adapt to different sizes or shapes, and for other purposes, such as regulating or measuring fluid flow) or cap (a pipe fitting used to seal the end of a pipe).
