In contrast, cool white or daylight lighting works well for rooms with modern, cool-colored themes—such as those with grays, blues, and whites—(cool light: 3500K-6500K). This lighting complements the cool tones and adds a clean, crisp look that aligns with contemporary styles.

In cleanrooms, certain applications may need amber or red lighting. Semiconductor labs use yellow light to block 500nm UV light, preventing photoresist overexposure.

If you want a modern, clean look, you may prefer the cleaner, brighter feel of a cool white lamp (4000K+). Cool white light contains more blue light and looks brighter to the eye (this is why cool white bulbs have a higher lumen output when compared to the equivalent warm white bulb).

Yellow lighting creates a cozy, inviting feel, ideal for living rooms and bedrooms, boosting relaxation by 30%. White lighting is clean and energizing, perfect for kitchens and offices, enhancing alertness by 20%. Use yellow light for a restful bedroom and white light to boost office productivity.
