1. Product Overview
The OttLite 13-Watt Replacement Tube with Electronic Ballast (Type E) is designed to provide natural daylight illumination for your compatible OttLite lamp. This bulb is specifically for lamps purchased after 2008 that utilize an electronic ballast. It delivers low-heat, low-glare light, helping to reduce eyestrain and show colors with incredible accuracy.
Important Note: This bulb is not compatible with lamps purchased before 2008, which require a magnetic ballast (Type A) tube.

2. Identifying the Correct Bulb
It is crucial to confirm that you are selecting the correct replacement tube for your OttLite lamp. There are two main types of 13W replacement tubes: Electronic (Type E) and Magnetic (Type A).
2.1. Lamp Purchase Date and Ballast Type
- If your lamp was purchased after 2008, you likely need the Electronic Ballast (Type E) tube. Look for an "E" on your current tube or its packaging.
- If your lamp was purchased before 2008, you need the Magnetic Ballast (Type A) tube.

2.2. Bulb Length and Model Numbers
The Electronic Ballast (Type E) replacement tube is approximately 7 inches long. Verify this length against your existing bulb or lamp shade.
Additionally, check the base of your current bulb for one of the following model numbers, which indicate compatibility with the Type E electronic ballast:
- T1333E
- Z17113
- 7T13CH-CE
- B413SP
- 7T13CH-SE
- T59J33

3. Installation Instructions
Follow these steps to safely replace your OttLite 13W tube:
- Power Off: Ensure your OttLite lamp is unplugged from the power outlet before attempting any bulb replacement.
- Remove Old Bulb: Carefully grasp the base of the old bulb and gently pull it straight out from the lamp socket. Avoid twisting or bending the bulb, as this may cause breakage.
- Insert New Bulb: Align the pins on the base of the new OttLite 13W Electronic Ballast (Type E) tube with the slots in the lamp socket. Gently push the bulb straight into the socket until it is firmly seated. Do not force the bulb.
- Test: Plug the lamp back into the power outlet and turn it on to confirm the new bulb is working correctly.

6. Troubleshooting
If your new OttLite 13W replacement tube does not illuminate after installation, consider the following:

- Improper Installation: Ensure the bulb's pins are fully and correctly seated in the lamp socket. Gently remove and re-insert the bulb, ensuring a secure connection.
- Power Supply: Verify that the lamp is securely plugged into a working power outlet. Test the outlet with another device if unsure.
- Lamp Malfunction: If the bulb is confirmed to be the correct type and properly installed, and the power supply is working, the issue may lie with the lamp itself.
