1. Product Overview
The OSRAM LED T5 HF L13 SHORT linear tubes are designed as a direct retrofit replacement for traditional T5 fluorescent lamps operating on electronic ballasts (HF). These LED tubes offer efficient, cool white light with a color temperature of 4000 Kelvin, providing a luminous flux of 850 lumens while consuming only 7 Watts of power.
Key features include:
- Efficient Illumination: High-quality LED light with consistent cool white color (4000K).
- Long Lifespan: Designed for extended operation, lasting up to 30,000 hours.
- Energy Saving: Consumes significantly less energy (up to 46% less) compared to traditional fluorescent tubes.
- Instant Start: Provides immediate light without flickering.
- Safety Compliance: RoHS compliant, free from hazardous substances like mercury, lead, cadmium, and chromium IV.
- Glass Tube Design: Prevents sagging over time.
These tubes are suitable for general lighting applications in various indoor environments such as homes, corridors, garages, workshops, public buildings, kitchens, and under-cabinet lighting. They are compatible with many common electronic ballasts (EVG).

2. Safety Instructions
Before installation or maintenance, please read and adhere to all safety guidelines to prevent injury or damage to the product. Always ensure the power supply is disconnected before handling the tubes.
- Power Disconnection: Always switch off the power supply at the main circuit breaker before attempting any installation or removal.
- Qualified Personnel: Installation should ideally be performed by a qualified electrician or a person with appropriate technical knowledge.
- Compatibility: Ensure the existing luminaire's electronic ballast is compatible with these LED tubes. Refer to the OSRAM compatibility list if unsure.
- Indoor Use: Primarily designed for indoor use. For outdoor applications, ensure the luminaire is specifically rated for outdoor use and provides adequate protection (e.g., IP rating).
- Temperature Range: Suitable for ambient temperatures between -20 °C and +45 °C.
- Handling: Handle glass tubes with care to avoid breakage.
3. Installation Guide
These LED tubes are designed for easy, quick, and safe replacement of existing T5 fluorescent lamps without requiring rewiring, provided they are used with compatible electronic ballasts (HF).
- Disconnect Power: Ensure the power supply to the luminaire is completely switched off at the main circuit breaker. Verify with a voltage tester if necessary.
- Remove Old Tube: Carefully remove the existing T5 fluorescent tube from its fixture. Dispose of the old tube according to local regulations.
- Insert LED Tube: Align the G5 pins of the OSRAM LED T5 HF L13 SHORT tube with the sockets in the luminaire. Gently push and twist the tube until it is securely seated.
- Restore Power: Once the LED tube is securely installed, restore power at the main circuit breaker.
- Test Functionality: Switch on the light to confirm proper operation.
Note: These tubes are designed for operation with electronic ballasts (EVG) and do not require a starter. Do not attempt to use them with magnetic ballasts or without a compatible ballast.

5. Maintenance
OSRAM LED T5 HF L13 SHORT tubes are designed for minimal maintenance due to their long lifespan and durable construction. Regular cleaning and inspection are generally sufficient.
- Cleaning: Ensure the power is off before cleaning. Gently wipe the tube with a soft, dry, or slightly damp cloth. Avoid abrasive cleaners or harsh chemicals.
- Inspection: Periodically check the tubes and their connections for any signs of damage or loose fittings.
- Replacement: Due to the long lifespan, replacement is infrequent. When replacement is necessary, follow the installation guide (Section 3).
6. Troubleshooting
If you encounter issues with your OSRAM LED T5 HF L13 SHORT tubes, consider the following troubleshooting steps:
- Tube Not Illuminating:
- Check if the power supply to the luminaire is active.
- Ensure the tube is correctly and securely seated in the fixture.
- Verify that the existing electronic ballast is compatible with LED T5 tubes. Incompatible ballasts may prevent the tube from lighting or cause damage.
- Test with another known-working LED tube if available, or test the tube in another compatible fixture.
- Flickering or Irregular Light:
- This often indicates an incompatibility issue with the electronic ballast. Ensure the ballast is suitable for LED T5 retrofit tubes.
- Check for loose connections.
- Reduced Brightness:
- Ensure the tube is clean and free from dust or obstructions.
- Verify the ambient temperature is within the recommended operating range (-20 °C to +45 °C).
If problems persist after following these steps, contact a qualified electrician or OSRAM customer support for further assistance.
