Smart LED Bulb Yeelight D1 (1 pc) — Wi‑Fi RGBW Smart Light, Tunable White

The Yeelight D1 Smart Bulb is a Wi‑Fi enabled RGBW LED lamp that combines tunable white (2700–6500K) and full-color lighting with up to 1300 lm of brightness. It supports fine 1000‑level dimming and offers smooth transitions and default power‑on states for consistent behaviour. The bulb is intended for general indoor use and can serve both as a primary illumination source and as an accent for atmosphere and scenes.

Advantages

The bulb delivers a wide color temperature range and millions of RGB colors, allowing precise adjustment of light for different activities. Adaptive Lighting automatically modifies brightness and color through the day to better match circadian needs. Matter over Thread connectivity ensures broad compatibility with major smart home ecosystems, while app and voice control, grouping, scenes and scheduling provide flexible management options.

Suitable for

• Living rooms and bedrooms where both general lighting and mood lighting are required
• Home offices and study areas that benefit from tunable white for focus
• Smart home setups using Apple Home, Google Home, Amazon Alexa or Samsung SmartThings

When it may not be suitable

The Yeelight D1 is designed for indoor fixtures with a standard E27 socket and mains power; it is not intended for outdoor, damp or non‑standard installations. A Matter controller with Thread Border Router support is required to use Matter over Thread features—without such a controller some advanced smart home integrations may not be available.

How to use

Screw the bulb into a compatible E27 socket and apply mains power. Use the Yeelight app or a compatible smart home platform to add the bulb and configure settings.

What to consider before purchase

• Requires a standard E27 socket and mains power
• Matter over Thread features require a Matter controller with Thread Border Router support
• Yeelight app integration may require additional hub hardware for some advanced automations

Usage recommendations

Use warmer color temperatures (around 2700–3000 K) for evening relaxation and cooler temperatures (5000–6500 K) for daytime tasks. Create scenes and schedules in the Yeelight app or your smart home platform to automate transitions and maintain consistent lighting behaviour.
