LED bulbs are the most common choice for home lighting today, thanks to their high efficiency, long lifespan and low power consumption. When choosing LED bulbs, you should consider several key factors. First, the base type: E27 is widely used in most countries, while E26 is common in North America. Second, power and brightness: higher power usually means higher lumens, so you need to match the brightness to the room size. Third, color temperature: warm white light (3000K) is suitable for bedrooms and living rooms, while cool white light (6000K) works better for offices and kitchens. Finally, check the CRI rating, which affects color rendering. Choosing the right LED bulb can help you save energy and create a comfortable lighting environment.
