Philips Hue Smart 40W ST19 Filament Bulb 4-Pack - Warm-to-Cool White

In this review the Philips Hue Smart 40W ST19 Filament LED Bulb 4-pack is presented as a tasteful, functional lighting upgrade for indoor spaces where adjustable white light and vintage styling matter most. The bottom line: this kit is best for homeowners or renters who want reliable smart control, a pleasing filament look, and a range of warm-to-cool white tones to set mood and task lighting. Its single biggest selling point is the combination of authentic Edison-style aesthetics with the White Ambiance range and app or voice control for real everyday convenience.

Key Features

• Four bulbs included: The box contains four ST19 filament bulbs so several fixtures can be updated at once without buying individual units.
• Adjustable white light: Choose warm-to-cool white to relax, read, focus, or energize a room with precise preset light recipes.
• Smart control options: Control directly by Bluetooth or pair with a Hue Bridge for remote access, automations, and a stable connection that does not rely only on home Wi-Fi.
• Voice assistant compatibility: Set up voice control in the Hue app and use Alexa, Google Assistant, or Apple HomeKit to turn lights on, off, or change temperature hands-free.
• Vintage filament design: The ST19 vintage Edison look works well in exposed fixtures, lamps, or wall sconces where appearance matters as much as light quality.
• Preset light recipes: Built-in modes such as Energize, Relax, Concentrate, and Read simplify choosing the right color temperature for daily activities.

Who It's For

This pack is aimed at people who value style and flexibility: those who want a warm vintage bulb look but also need modern smart lighting features like app control, voice commands, and preset scenes. It suits living rooms, dining areas, bedside lamps, and open fixtures where the bulb is visible.

Buyers who need very high lumen output or expect a 60W-equivalent brightness should look elsewhere, since customers note this is a 40W-equivalent bulb with about 550 lm per bulb. Also, if full local integration with third-party hubs is required, check compatibility for your specific smart home platform before purchase.

Pros & Cons

Pros

• Attractive vintage filament ST19 design that complements exposed fixtures and lamps.
• Wide warm-to-cool white range with useful presets for different daily activities.
• Multiple control methods: Bluetooth for simple setups and the Hue Bridge for remote access and automations.

Cons

• Higher price compared with basic LED bulbs; some customers find it less good value for money.
• Not as bright as a typical 60W-equivalent bulb, so may be insufficient for heavy task lighting needs.
