Better than expected and easier
These lights are so much better than I expected. The app is easy once you get it. I lable each light separately and program each one differently or get them all thr same. So easy. I will never buy regular light bulbs again

Lepro B3 AI Smart Light Bulbs – 1500LM 100W Equivalent A21 Bulb
I recently installed the Lepro LightGPM 4 smart bulb, and it’s honestly been a game-changer for making our home feel more lively and personalized. What I love most is how intuitive it is—just telling the app what vibe I want, whether it’s cozy movie night, a festive holiday glow, or a lively party atmosphere, and it instantly sets the perfect mood. The AI lighting designer learns my preferences over time, so it gets better and more tailored the more I use it.The upgraded voice control is so convenient—no fumbling through presets or complicated setups. I can just say, “Alexa, set the mood to party” or “Google, turn on relaxing white light,” and it happens immediately. It’s especially helpful when I’m busy with the kids or cooking dinner and need quick control.The brightness is impressive—bright enough to light up our large living room with vibrant, crisp colors, and the CRI 90+ makes everything look true-to-life. Plus, it’s energy-efficient, so I feel good about reducing our electricity bills while still enjoying brilliant lighting.One of my favorite features is snapping a photo of our space or a movie poster, and the bulb instantly creates a theme that matches the vibe. It’s such a fun way to customize the atmosphere for movie nights or special occasions. And with LightBeats music sync, the lights dance along to our favorite songs, turning any gathering into a fun, energetic party.With millions of colors and adjustable white tones, I can set the perfect lighting for reading, relaxing, or entertaining. It’s a sleek addition to our home that’s both functional and stylish, and I love how easy it is to control with just my voice or a quick tap on the app. If you want smart, customizable lighting that makes your space come alive, I highly recommend giving the Lepro LightGPM 4 a try!

Works with Google and Alexa and Super easy to setup!
These lights arrived in good condition and on time. Packaging was standard, as with most other led brand lights. Installation was really simple. Twist into the socketvand the bulbs automatically go into pairing mode.From there , instructions are provided to hook to either android or apple via a QR code. It asks you to install the Lepre companion app, which is common for most WiFi and digital assisted products. Then I opened the Lepro app and added the devices, following the apps instructions. It will ask for your Wi-Fi password to connect to the lights for pairing. ( I might add that as soon as I clicked the Lepro app’s add device button, the bulbs were already listed as ready to pair automatically. So, no searching for devices or having to manually add individual bulbs. Each individual bulbs was listed and ready to add individually.) Easy!After doing so, (I use Google home) , all I had to do was open the Google Home app and connect the Lepro app to my assistant software account. I then chose a room to add them to within the Google Home app, and Wala! They worked like a charm!These lights get very bright at 100%, so I tend to keep them between 65 and 75% brightness. You can also change colors and color temperature via the Lepro app, or within you chosen assistant app via voice or manually. There is little to no lag between commands either, providing you have a strong Internet signal.Overall a very good experience for my first Lepro device. I would definitely recommend these to anyone wanting to add smart functionality to their home lighting. They fit standard light bulb fixtures and are smart to remember what the lights were set to after turning the power switch off and on. Nice! Highly recommended!

I love smart bulbs
I love having a smart home, and these lightbulbs do not disappoint! Connecting them to my Alexa was quick and easy, and I really enjoy the color options. They’re perfect for holidays like Christmas and Halloween or just setting a mood.They respond to voice commands, and it’s so convenient to tell Alexa to turn the lights off or set up custom routines. So far, I’m really impressed with the brightness and flexibility. I’ll update later on how long they last, but for now, these are a fantastic addition to any smart home setup!

These light bulbs work perfect with my Google home home and were very easy to install and Google voice can command them to make a room a certain color. For the special effects. You have to use their app but that’s not much of a problem considering how often you’ll actually use special effects like police car lighting. I would recommend this product and intend to purchase more and do all my outside scones lighting.

Pretty bright for RGB bulbs
Amazon Customer –
I received the Lepro B3 smart bulbs. I don’t use Alexa or Google Assistant devices, so I’ve been trying out these bulbs using the Lepro app. In terms of performance, I’ve been quite happy. I’m not someone who strives for multiple lighting settings. I was most interested in using one of these bulbs with a lamp where the on-off switch is very hard to reach. Problem solved! Now my phone is the light switch. I did play around with it and it’s quite neat to customize colour and brightness. I tried to do some voice control stuff, but I think I’m a decade too old to really grasp that functionality to its fullest. My only concern about these light bulbs was that I didn’t see the electrical certification marks for Canada. I’ve seen other Lepro products before and I know their other products have them, so I was quite surprised by this omission. I hope it was just a printing oversight on the product because everything seems to work well. I love the bulbs, but because of the missing certification marks I can’t give this product full marks.

The light is very bright, perfect for me. It’s linked to Alexa and you can dimm the light and change colors. But won’t have as many options as with the specific app.I recommend.
