Lepro’s B3 smart bulbs offer a practical entry into AI-assisted lighting. The promise is straightforward: the more you use them, the more the system learns your color and scene preferences. It’s a useful step up from scrolling through endless static presets.

At 1500 lumens, these A21 bulbs provide ample brightness for most rooms. The RGBWW color range is vibrant, and the white temperature tuning is smooth. You control everything through the Lepro app or voice assistants. In daily use, asking the app to “create a cozy evening scene” or “match the mood of this movie” feels more intuitive than manual adjustments. The 12-watt power draw is efficient for the output.

The four-pack makes it easy to outfit multiple fixtures. Setup is standard for smart bulbs, requiring a 2.4GHz Wi-Fi network. While the AI feature is a genuine differentiator, it requires consistent use to become truly personalized. For the price, you get capable, bright bulbs with a clever layer of automation that actually improves with time.
