Lepro B22 AI Smart Bulb (B22) 12W, 1521LM, 16 million colours — schedule, timer & voice control
Product description
If you’re tired of “one colour fits all” smart bulbs, the Lepro B22 AI Smart Bulb is aimed at people who want their lighting to feel more personal. It supports 16 million colours, adjustable brightness, a warm-to-cool white temperature range, plus scheduling and group control via the Lepro app.
It’s also pitched as a more adaptive setup than basic bulbs: you can tell the app what you like, and it “learns” your preferences over time. That said, it’s not perfect for everyone—especially if you only want simple on/off control or you’re not keen on app + Wi‑Fi steps.
The essentials
This is a B22 smart light bulb that’s designed for indoor rooms and work areas. On paper, it sits in the “proper smart” bracket: colour control (16 million hues), warmth-to-cool lighting (from 2700K warm to 5700K cool), and practical automation like a timer for auto-on/off.
Where it gets more interesting is the AI angle. The product description frames the bulb as a “Personalized AI Lighting Designer”, encouraging you to set up lighting the way you actually use your space—holiday vibes, party atmosphere, or matching the mood of a movie or game theme. The more you use it, the more the lighting design is intended to fit your preferences.

It also includes photo-based image recognition: if you’re not sure how to describe the look you want, you can take a photo of your room and get a lighting design tailored to the space, or upload an image such as a movie poster or game character to theme your area.
Key takeaways
What you’ll notice day to day is how quickly you can shift mood. With the app, you can change brightness and colours without wrestling with lots of manual preset scrolling. The bulb’s 12W power draw is positioned as maintaining brightness and colour quality without extra power use, while the stated light output (1521LM) is aimed at rooms where you don’t want the bulb to feel underpowered.
There’s also a music-sync feature (LightBeats Music Sync). It uses sound-sensing and “algorithms” to sync light pulses, fades and shifts to music beats—useful if you’re hosting, having a birthday, or just want your living room lighting to follow what’s playing.


What matters most in real life

Installation is designed to be straightforward: screw the bulb in, then connect it to the Lepro app (with the important note that the bulb must be connected through 2.4 GHz Wi‑Fi via the Lepro app).
For voice control, the description says it works with Alexa and Google Assistant, but the setup path matters. The connection to Alexa is routed through the Lepro app, and the Alexa device needs to be “found through the Lepro app” otherwise the link won’t work (per the guidance provided).
There’s also group control, so you can combine multiple bulbs (for example, living room and bedroom) and manage them together in the app. If your goal is consistency across rooms—same brightness level or same colour mood—group control is the kind of feature that feels small until you start using it.

Getting the most from it (and the limits)
It makes sense if you actually want to use the app regularly and you’ll experiment with moods. The AI “designer” concept is built around learning your likes and effects, and the photo/image recognition approach is there for convenience when you don’t want to describe lighting details in text.
If you’re just looking for a reliable bulb that you can switch on and off, this may be more than you need. The usefulness depends quite a lot on whether you’re comfortable with initial setup steps (especially 2.4 GHz Wi‑Fi + Lepro app connection) and whether you’ll make use of scheduling, group control or music sync.


Also, if your home setup doesn’t support 2.4 GHz Wi‑Fi for smart devices, you may hit a practical blocker—nothing about the product description suggests a workaround.
Quick examples

- Evening wind-down: set the colour temperature towards the warm end (2700K), lower brightness for eye comfort, then use a schedule so the light is ready when you want to start relaxing.
- Movie/game night: tell the app your theme (or upload an image) and switch to a matching colour mood, then tweak brightness as the scene changes.
- Music night: play something with a steady beat, turn on LightBeats Music Sync, and let the bulb pulse and shift in time—more “atmosphere” than a light show that you fully control.
In the box
The provided information doesn’t include details on what’s included beyond the bulb itself, so it’s worth checking the listing’s “In the box” section before ordering if you need anything more than the smart bulb.
Should you buy it?
Worth considering if you want a B22 smart bulb with proper colour range (16 million colours), warm-to-cool white control, schedules, group control, and features that go beyond basic presets—especially if you’ll use the app to personalise lighting over time.

Better avoided if you only want simple smart switching, or if you know you can’t (or don’t want to) set up and connect devices through 2.4 GHz Wi‑Fi in the Lepro app. It also might feel like overkill if you’re unlikely to try music-sync or photo-based mood creation.
Buying decision tip: make sure you’re comfortable with the app-first approach and the connection guidance for Alexa, then judge it based on how often you’ll actually use those extra modes.


Mini FAQ
Does it need 2.4 GHz Wi‑Fi to work with the app?
Yes. The description specifically notes the bulb must be connected via 2.4 GHz Wi‑Fi through the Lepro app.

What lighting adjustments are available?
You can change brightness, switch colour temperature between 2700K (warm) and 5700K (cool), and choose among 16 million colours.
How does the music sync work?
It uses sound-sensing and LightBeats algorithms to sync light changes with music beats, with pulses, fades and shifts intended to match the rhythm.
Is voice control straightforward?
The description indicates it works with Alexa and Google Assistant, but Alexa linking needs to be done through the Lepro app (and the Alexa device must be found through that process).
