Smarten up your lighting

Looking to add or expand smart lighting within your home? This 4-pack of Hue bulbs will cover a lot of ground. You can replace the standard bulbs in four of your light fixtures with these energy-efficient Hue A19 smart bulbs to add easy-to-control, dimmable, warm white light all around you.

No Bridge required 

One of the only complaints I've heard about Philips Hue bulbs is that you have to have a separate Bridge to control them. Well — not anymore. These bulbs can connect to your mobile device using Bluetooth. You can then use the Hue mobile app to control up to ten lights in one room of your home.

Use your voice

You can also control these bulbs hands-free if you've got an Amazon Alexa or Google Home device. That means you can turn your lights on or off, dim them, and recall your favorite presets just by asking.

Add wall control

Operating your lights with an app or your voice is fun, but you might find that some members of the household prefer a good old fashioned wall switch. If so, you can pick up a Hue dimmer to add a wall-controlled option to your Bluetooth-based system.

Expand your system with a Bridge to do more

If you want to do even more, you can add a Philips Hue Bridge (sold separately). Then, you can control up to 50 Hue devices — even when you're not at home. The Bridge also adds compatibility with other Hue accessories — like the Tap — and voice control via Apple HomeKit and Microsoft Cortana.

You can also set timers and create routines. For example, a “wake up” routine gradually increases the brightness in your bedroom to mimic the effect of sunrise. That sure beats the buzz of an alarm clock. And if you want to add some color to your system, check out Hue's collection of White and Color Ambiance products.

More details on the Philips Hue White A19 Bulb 4-pack

Product Research


Overview: The Philips Hue White A19 bulb (#476977 4-pack) is a wirelessly controllable, highly efficient LED light bulb. Philips Hue light bulbs are designed to be added to an existing Hue Personal Wireless Lighting System. The bulb produces soft, warm white light (color temperature 2700 Kelvin). You can control the bulb (turn on/off, dim/brighten) via Bluetooth in a single room, or pair it to a Hue Bridge as part of a whole home smart lighting system. The bulbs in this 4-pack are covered by a 3-year warranty.

Note: The bulb is not suitable for use with external dimmers, photo controls, occupancy sensors, or timing devices. It is designed for indoor use only.

Light Bulb: The White LED bulb can be used in standard light sockets (Edison E26 screw base). It has an A19 form factor, and is 2.4" at its widest point and 4.4" tall. The bulb is rated at 9.5 watts and 800 lumens, with a brightness equivalent to a 60-watt incandescent bulb. It has an estimated nominal lifetime of 25,000 hours, and up to 50,000 switching cycles. The internal software is automatically upgradable via Bluetooth or when connected to the Philips Hue bridge. The bulb has a beam angle of 160° (±20°), and instant 100% light output at startup.

Philips Hue App: The Philips Hue app, when used with the Hue Bridge, gives you full home control of your Philips Hue lights. Within the full Hue Lighting System, you can set timers and schedules, control lights away from home, set wake-up and go-to-sleep routines, and sync the lights to your music, movies, and video games. Additional Hue products can be added to the system, up to a maximum of 50 bulbs and 12 Hue accessories that can be controlled by a single bridge. Bluetooth control has been incorporated into the Philips Hue app, allowing control of up to 10 Bluetooth-compatible Hue products from within the room. The app is available for Apple devices running iOS 14.0 or later, or for Android devices running Android 10 and up.

Bluetooth Control: The bulb is Bluetooth-compatible, allowing you to control the light from the room without the Hue Bridge. Up to 10 Bluetooth-enabled lights can be controlled from your smartphone or tablet from up to 30 feet away. You can turn the lights on or off, dim or brighten the bulb, and apply Light "recipes" for everyday tasks. You can even control them with your voice through the Google Assistant or Amazon Alexa. Bluetooth control requires the Philips Hue app.

Note: The separate Philips Hue Bluetooth app is no longer available.

Hue Compatible Products: Hue lighting products not only work within the Philips Hue universe, but, when paired with the Hue Bridge, are compatible with many third party products, including many of the top voice assistants. Hue products work with Apple HomeKit, Amazon Alexa, Google Assistant, and Cortana by Microsoft. Using simple voice commands, you can turn the lights on and off, dim or brighten the lights, and set a light scene. In addition, other "Friends of Hue" include IFTTT (If This, Then That), Logitech, Nest, Xfinity, and SmartThings.

Hue Personal Wireless Lighting: The Hue Personal Wireless Lighting System lets you individually control the lighting products in the system using your smartphone or tablet. Philips Hue lights are available in three color ranges: White Ambiance, White and Color Ambiance, and White. Through the Hue app, and with the right Hue products, you can do the following:

  • Paint With Light: You can choose from 16-million colors to light, or change the look of, your room. Your favorite light settings can be saved for later recall. (Requires Color Ambiance bulbs)
  • Sync Lights With Movies or Music: The lights can be synchronized to change with the scenes in a movie, or pulse to the beat of your music. (Third party apps may be required.)
  • Create An Ambience: The app lets you use different shades of white light to create an ambience. The bulbs can produce shades of light from energizing cool daylight to relaxing warm white light.
  • Light Mood Presets: Preset light moods let you instantly change the lights in the room to fit the moment. Optimal settings are available for reading, relaxing, concentrating, and energizing.
  • Wake Up: Gradually increasing light intensity helps to gently wake you up with light, similar to the natural light of the morning sun.
  • Light Schedules: The lights can be programmed to come on and go off at a preset time, including lighting rooms at different times. At night, you can let the lights turn off gradually, so you don't have to worry about leaving lights on.
  • Remote Lighting Control: When you're away from home, you can turn lights on or off from your smartphone. You can also check the status of your lights when you're not there.
  • Geofencing: When the bridge detects that your smartphone is within a certain distance, it will automatically turn lights on or off. For example, as you approach your house, your lights will automatically turn on so you won't have to enter a dark room. (Third party apps may be required.)

Can these be used in recessed lighting receptacles where I currently have flood lights?

Yes, but will not be as luminous below as flood would due to reflection
