2. Safety Information
WARNING: To reduce the risk of electric shock, fire, or injury, always turn off power to the fixture at the circuit breaker or fuse box before installation or maintenance.
- Ensure the fixture is compatible with Type A (Plug and Play) LED tubes. These tubes are designed to work with existing electronic or magnetic ballasts.
- Do not attempt to bypass the ballast or wire directly to line voltage unless specifically instructed by a qualified electrician. This product is designed for ballast-compatible operation.
- Do not use with dimmers unless the ballast and fixture are specifically rated for dimmable LED tubes.
- Handle glass tubes with care to prevent breakage.
- This product is intended for indoor use in dry locations.
- Consult a qualified electrician if you are unsure about the compatibility or installation process.
3. Package Contents
Your package should contain the following items:
- 10 x Philips Plug and Play 5-CCT Type A LED Tube Light Bulbs (Model: 591965)

4. Setup and Installation
These Philips LED tubes are designed for simple "Plug and Play" installation, directly replacing T8 and T12 linear fluorescent tubes without rewiring.
- Turn Off Power: Before beginning installation, ensure the power to the fixture is completely turned off at the circuit breaker or fuse box. Verify power is off using a voltage tester.
- Remove Existing Fluorescent Tubes: Carefully rotate and remove the old fluorescent tubes from the fixture. Dispose of fluorescent tubes according to local regulations.
- Select Color Temperature (CCT): Locate the CCT selector switch on one end of the Philips LED tube. Before installing, choose your desired color temperature:
- 3000K (Bright White)
- 3500K (Neutral White)
- 4000K (Cool White)
- 5000K (Daylight)
- 6500K (Daylight Deluxe)

5. Operating Instructions
Once installed, the Philips Plug and Play LED tubes operate like traditional fluorescent tubes. Simply use your existing light switch to turn the lights on and off.
5.1 Color Temperature Selection
The color temperature (CCT) is selected via a switch on the end of each tube prior to installation. Once installed, the CCT cannot be changed without removing the tube and adjusting the switch. Ensure your desired CCT is set before final installation.
- 3000K (Bright White): A warm, inviting light, similar to traditional incandescent bulbs.
- 3500K (Neutral White): A balanced white light, suitable for general purpose areas.
- 4000K (Cool White): A crisp, clean white light, often used in offices and task lighting.
- 5000K (Daylight): A bright, bluish-white light, mimicking natural daylight.
- 6500K (Daylight Deluxe): A very cool, bright white light, ideal for areas requiring high visibility.
6. Maintenance
Philips LED tubes require minimal maintenance.
- Cleaning: Ensure power is off before cleaning. Wipe the tubes with a soft, dry, or slightly damp cloth. Do not use abrasive cleaners or solvents.
- Replacement: These LED tubes have a long lifespan. If a tube fails, follow the installation steps in reverse to remove it, and replace it with a new Philips Plug and Play LED tube of the same model.
