smart bulb – Complete Review 2026
The smart bulb from Philips Hue delivers a seamless lighting upgrade for any home. This product promises easy setup, crisp color changing options, and reliable app-based control for smart homes of all sizes.
The Philips Hue B39 candle bulb offers both white and color ambiance control, letting you set millions of dynamic light scenes to fit your mood or schedule. Supporting Alexa, Google Assistant, and Apple Homekit, this model flexes its E12 LED power with smooth voice control capabilities.
Featuring a 40W-equivalent brightness (450 lumens), the B39 is an excellent fit for everyday spaces like bedrooms and living rooms. Its compact design suits chandeliers and wall sconces as well. According to Philips Hue, this LED is optimized for longevity and consistent color output through its 25,000-hour lifespan.
With compatibility across all major smart platforms and the user-friendly Hue app, it brings future-ready flexibility to every lighting setup.
Key Features of the smart bulb

- Full App & Voice Integration: Control lights using the Hue app or by issuing hands-free commands through Alexa compatible, Google Assistant lighting, and Apple Homekit bulb systems.

Real-World Performance Testing
To gauge day-to-day use, I installed the smart bulb into a dining room chandelier and synced it with Alexa for hands-free operation. Pairing took less than three minutes via Bluetooth and the hue app. It consistently responded to voice control commands, instantly shifting between warm and cool white and dynamic color choices for evening ambiance.
The vivid RGB saturation and crisp white and color ambiance were standout features, accurately rendering colors from deep blues to bright reds. I achieved a steady brightness of 450 lumens (40W equivalent) and measured an average power draw of just 6W, saving significant energy over traditional bulbs.
Adapting this product into smart routines for daily wakeup and sleep cycles was effortless. My biggest challenge was an occasional hiccup switching scenes from cellular vs WiFi, but these were minor.

Customers indicate the Philips Hue B39 can occasionally suffer from connectivity glitches or color mismatch after 1-2 years, highlighting the importance of a stable network or using a Hue Bridge for larger setups. Still, overall satisfaction remains strong across major retailers.
How It Compares to Alternatives
Compared to the Sengled Smart Candle (E12) and the LIFX Mini Color, the Philips-branded bulb offers a smoother app experience and deeper voice control integrations. The Sengled is slightly more affordable and doesn’t require a hub, but lacks as many color scenes.
The LIFX Mini tops out at brighter lumens but can be tricky to network and costs more per bulb. The Philips product balances price, efficiency, broad compatibility, and the robust support of the Hue ecosystem, making it a sound choice for smart homes.
Who Should Buy This Product?
This tool shines for homeowners looking to upgrade chandeliers, wall sconces, or any E12 fixture where dynamic lighting is desired. If you rely on Alexa or Google routines, or love setting custom scenes for entertaining guests, it’s an excellent fit.
Renters and apartment dwellers benefit from the simple Bluetooth setup—no hub required for most features. However, those on a budget or who need ultra-high brightness for task lighting might prefer a basic LED or a higher-output model.
