3. 操作
3.1 Color Temperature Selection (5CCT)
Your NUWATT recessed lights feature a 5CCT switch located on the junction box, allowing you to select from five different color temperatures. This selection must be made 前に the fixture is fully installed in the ceiling. The available options are:
- 2700K: ソフトホワイト（温かく心地よい光）
- 3000K: Warm White (slightly less yellow than 2700K)
- 3500K: ニュートラルホワイト（バランスの取れた自然光）
- 4000K: Cool White (crisp, energetic light)
- 5000K: Daylight (bright, blue-white light)
To change the color temperature, slide the switch to the desired setting. Once set, the light will emit the chosen color temperature when powered on.

3.2 調光機能
These recessed lights are dimmable from 10% to 100% when paired with a compatible dimmer switch. Ensure your dimmer switch is designed for LED lighting to prevent flickering or damage. The dimming capability allows for adjustable brightness to suit various moods and activities.
