How do you identify LED light bulbs?

To identify LED light bulbs, look for labeling that indicates "LED" on the packaging or the bulb itself. Check the wattage; LED bulbs typically use lower wattage compared to incandescent bulbs while providing similar brightness. Additionally, observe the bulb's shape and base type, as these can vary (e.g., A19, GU10). Finally, consider the color temperature, which is often displayed in Kelvin (K) to indicate whether the light is warm or cool.
