No, you don't necessarily need the Hue Bridge to use these bulbs, but it is recommended to access all the advanced features. Here are the key points:

- You can control the bulbs menggunakan the Philips Hue Bluetooth app, allowing you to control up to 10 bulbs in a single room without the Bridge.
- However, the Hue Bridge is essential for enabling features like remote control, voice control with assistants like Amazon Alexa and Google Assistant, and automated routines.
