Product Information
Full details
The Paulmann 28835 LED Tube is designed for users looking to replace traditional halogen tubes in ceiling uplights and wall/ceiling luminaires. Its key benefit is significantly lower energy consumption and a much longer service life compared to halogen alternatives, while providing comfortable, eye-friendly warm white light. A potential caveat is its energy efficiency rating of E, which may not be suitable for those prioritizing the highest energy savings.

FAQs
What is the main advantage of using this LED bulb over a halogen tube?
The main advantages are significantly lower energy consumption (13W vs 100W equivalent) and a much longer service life (15,000 hours vs typically 1,000-2,000 hours for halogen), leading to cost savings and reduced maintenance.
Is this LED bulb compatible with all R7s fittings?
It is designed for R7s fittings, but ensure your luminaire can accommodate its dimensions (118mm height, 28mm diameter) and that the fixture's electrical compatibility is suitable for LED replacement.
Can I use this bulb with any dimmer switch?
This bulb is dimmable, but it is recommended to use it with an R+C type dimmer for electronic transformers. Using it with incompatible dimmers may result in flickering or malfunction.
What does 'Eye friendly' mean in the product description?
'Eye friendly' indicates that the lamp is designed to emit comfortable, gentle light that minimizes eye strain, making it suitable for extended use during activities like reading or working.
What is the expected lifespan of this bulb?
The bulb has an expected lifespan of 15,000 hours, which is considerably longer than traditional halogen bulbs.
How does the energy efficiency class 'E' compare to other ratings?
Energy efficiency is rated on a scale from A (most efficient) to G (least efficient). Class E is a mid-range rating. While it offers savings over older technologies, bulbs with A, B, or C ratings are generally more energy-efficient.
What is the color temperature of the light?
The color temperature is 2700 Kelvin, which is classified as warm white. This provides a cozy and inviting light, similar to traditional incandescent bulbs.
Troubleshooting
Bulb does not light up
Ensure the power supply is on and the bulb is correctly seated in the R7s fitting. Verify that the fixture's wiring is functional. Check if the dimmer is set to an appropriate level if dimming is used.
Bulb flickers or is dim
Confirm the bulb is compatible with the dimmer switch (R+C for electronic transformers). If not dimming, check for loose connections in the fixture or a failing dimmer. Try the bulb in a different compatible fixture to rule out fixture issues.
Bulb turns off intermittently
This could be due to overheating if ventilation is poor, or a compatibility issue with the dimmer. Ensure the luminaire is properly ventilated and try operating without dimming if applicable.
Light color is not as expected
The color temperature is fixed at 2700K (warm white). If a different color temperature is desired, this specific bulb may not be suitable. Ensure the bulb is clean, as dirt can affect perceived light color.

Setup, Compatibility & Care
Setup:
- Ensure Power is Off: Always disconnect the power supply to the luminaire before attempting to replace the bulb.
- Remove Old Bulb: Carefully unscrew or unclip the existing R7s halogen tube.
- Install New LED Bulb: Insert the Paulmann 28835 LED tube into the R7s fitting, ensuring it is securely seated.
- Restore Power: Reconnect the power supply and test the new bulb.
Compatibility:
- Fitting Type: Compatible with luminaires using an R7s fitting.
- Dimensions: The tube measures 118mm in height and 28mm in diameter. Ensure your luminaire can accommodate these dimensions.
- Dimming: This bulb is dimmable. For optimal performance, use with a compatible dimmer (R+C type for electronic transformers). Check your luminaire's specifications for dimmer compatibility.
- Voltage: Operates on a standard 230V supply.
Care:
- Cleaning: For best performance and longevity, clean the bulb periodically. Ensure the power is off. Use a dry or slightly damp soft cloth to wipe the surface. Avoid abrasive cleaners or solvents.
- Ventilation: Ensure the luminaire has adequate ventilation, as LED bulbs still generate some heat, although significantly less than halogen bulbs.
