The answer depends on what you mean by "brighter."
- Brightness: Both warm and cool white bulbs can have the same brightness (measured in lumens). A 60-watt equivalent LED bulb, for example, will produce the same amount of light whether it's warm white or cool white.
- Perceived Brightness: Cool white bulbs often appear brighter because they emit more blue light, which our eyes are more sensitive to. Warm white bulbs, with their yellow-red hues, can feel more cozy and inviting.
In short, the "brighter" bulb depends on what you're looking for. If you want the most light output, choose a bulb with a high lumen rating, regardless of its color temperature. If you want a bulb that appears brighter and more stimulating, choose a cool white. If you prefer a warmer, more relaxing atmosphere, go with a warm white bulb.
