Philips Hue White Ambiance Filament ST72 - Smart LED bulb, transparent

The Philips Hue White Ambiance Filament ST72 Smart LED bulb is a decorative smart upgrade for standard light fixtures. This ST72-shaped filament bulb provides 550 lumens, comparable to a 40W incandescent lamp. It is a tunable white bulb with a colour temperature range of 2200K to 4500K. You can adjust the light from warm to cool white to suit different household activities. The bulb features built-in dimming, meaning no additional hardware is required. Each pack contains one transparent bulb designed for fixtures where the filament is visible.

The bulb uses a standard E27 screw base. It connects via Bluetooth or Zigbee—Wi-Fi is not supported—and a Hue Bridge is recommended for full network functionality. It is compatible with Amazon Alexa, Google Assistant, and Apple HomeKit for voice control. The LED is rated for a lifetime of 15,000 hours and 50,000 switching cycles. A 360-degree beam angle ensures even light distribution, and power consumption is 7 kWh per 1000 hours, with a standby draw of 0.5W.
