When a light bulb is rated at 60 watts, it means that it consumes 60 watts of electrical power when it is turned on. This power consumption determines the brightness of the bulb and is used to measure its energy usage.
The power rating of a light bulb is measured in watts (W), which represents the amount of electrical energy it consumes per unit of time. If a light bulb has a power rating of 60 watts (for example), it means it consumes 60 watt-hours of energy in one hour of operation.
A light bulb is typically measured in watts, which indicates its power consumption and brightness output. It can also be measured in lumens, which quantifies the amount of light produced by the bulb.
It is not possible to directly convert lumens to watts because they measure different things - lumens measure brightness while watts measure power consumption. The relationship between lumens and watts depends on the efficiency of the light source.
A 3 watt led light is not the same as a 45 watt bulb. A led light is a lot brighter.
