How are home LED bulbs rated?

Home LED bulbs are typically rated based on several key factors, including brightness measured in lumens, energy consumption in watts, and color temperature measured in Kelvin. The lumen output indicates how bright the bulb will be, while the wattage reflects its energy efficiency; lower wattage typically means less energy consumption for the same brightness. Additionally, the color temperature indicates the warmth or coolness of the light, with lower Kelvin values producing warmer light and higher values resulting in cooler, bluish light. Lifespan is also a crucial rating, often expressed in hours, indicating how long the bulb is expected to last.
