Lepro B22 AI Smart Bulb (4-pack) – 12W, 1521LM, 16 million colours with schedules and voice control

Key features worth knowing before you buy

The Lepro B22 AI Smart Bulb package is built for people who are tired of basic “set a colour and forget it” smart lighting. Instead of keeping everything generic, this bulb leans on an app-led approach and aims to make your lighting feel more personal over time. It’s a 12W B22 smart bulb with a brightness figure of 1521LM and colour options described up to 16 million hues.

On paper, it covers a lot of everyday scenarios: switching colours and brightness, changing the white temperature from warm 2700K to cool 5700K, setting schedules/timers, grouping multiple bulbs for easier control, and syncing light to music using its LightBeats feature. It also supports voice control with Alexa and Google Assistant, as long as you connect it through the Lepro setup.

What you’ll notice day to day

Where this bulb feels different is the “AI lighting designer” angle. The idea is that you can tell the app what you like (colours/effects), and it remembers your favourites. The more you use it, the more the lighting design is intended to match your preferences. It’s not perfect—any app-based system depends on how much you actually engage with it—but if you enjoy experimenting with mood lighting, it may feel more rewarding than simple presets.

There’s also an image recognition feature: you can take a photo of your room (or upload something like a favourite movie poster or game character theme) to help generate a lighting design for that space. That can be handy if you struggle to describe what you want.

A micro example: imagine you’re setting up a living room for a film night. You’d likely switch from a cooler 5700K workspace feel to warmer 2700K and then pick a colour/effect vibe that matches the movie theme. With grouping, you can do the same across multiple rooms from one place, rather than tweaking bulbs one by one.

Brightness, colour and comfort (the practical side)

The bulb is positioned for indoor rooms and work areas, with a colour temperature range from warm 2700K to cool 5700K. You also get 16 million colours, plus brightness adjustments intended for eye comfort.

The sensible expectation here is mood lighting and routine-based light control, not a “studio-grade” colour calibration tool. The brightness rating listed (1521LM) suggests it should be workable for typical indoor use, but it can still depend on room size, ceiling height, and how many lights you have.

It’s also fairly straightforward to install: you screw it in, then connect it to the Lepro App. One detail worth taking seriously—setup needs a 2.4 GHz WiFi connection through the Lepro APP.

Scheduling, grouping and music sync

If you want lights that behave like routines rather than gadgets, the timer & schedule function is one of the more convincing elements. Auto-on/off scheduling can help with waking up to softer light or welcoming you home without fumbling in the dark.

Grouping is another convenience feature: you can combine multiple bulbs (for example, living room and bedroom) and control them together via the app with one tap, including brightness, colour, or on/off changes. That’s useful if your household doesn’t want to micromanage lighting.

Then there’s LightBeats music sync, which uses sound-sensing and “LightBeats algorithms” to pulse, fade, and shift in time with your music beats. It’s a feature aimed at gatherings and parties, and it can also make solo dancing feel less… awkward. Still, it’s worth noting that music-sync performance depends on your audio source and room acoustics—so it’s one of those “fun first” features rather than something you should judge like a professional stage system.

Compatibility and setup reminders

This bulb is described as working with Alexa & Google Assistant, with connection instructions that require you to do initial setup via the Lepro app. The guidance also says Alexa must be found through the Lepro app for the link to work.

Another setup limitation to keep in mind: the bulb must be connected to 2.4 GHz WiFi through the Lepro APP. If your home network doesn’t offer a 2.4 GHz option (or it’s not easy to select), you may end up spending longer on setup than you’d like.

Where it shines—and where it may fall short

It’s a good fit if you want:

• Colour variety (up to 16 million hues) plus a warm-to-cool white temperature range
• App-led personalisation, including remembering favourites
• Schedules/timers and the ability to group bulbs across rooms
• A music-sync lighting mode for social occasions

It may not suit you as well if you mainly want a very simple “one colour for the day” setup, or if you’d rather avoid app-based configuration and a 2.4 GHz WiFi requirement.

Also, because the “Personalized AI Lighting Designer” depends on how the app learns/records your preferences, it can take some time to feel truly tailored. If you want instant, fixed lighting scenes with minimal tinkering, you might feel that this approach is a bit more hands-on than you expected.

Should you buy it?

It’s worth buying when you’re after more than basic smart lighting—especially if you like mood lighting, want schedules and group control for convenience, and will actually use the app features (including personalisation and image-based theme ideas). The included 4-pack also makes it easier to expand lighting across rooms without buying bulbs one at a time.

You may want to skip it if you only need simple on/off control or you’re not comfortable with app setup and 2.4 GHz WiFi requirements. It also might not be the best match if you expect music sync to behave flawlessly in every situation, regardless of audio source or room setup.
