Why choose a 150cm LED tube mounting rail?
The 150cm length is a widely chosen standard in professional lighting. This size ensures optimal distribution of light in larger spaces, requiring fewer fixtures for even illumination. The advantages of this specific length include:
-
Wide light distribution: A 150cm rail covers a larger area than shorter variants, resulting in fewer shadows and better overall visibility.
-
Efficient setup: Thanks to higher light output per fixture, you need fewer installation points, saving time and costs for new projects or renovations.
-
Standardization: The 150cm size is a common standard, providing a broad range of compatible LED tube lights and fixtures.
Types of 150cm LED tube mounting rails available
150cm LED tube mounting rails come in two main variants, each with specific characteristics:
| Type of mounting rail |
Features |
Application |
| With integrated LED chips |
Fixed LED module, no separate tube required. Very energy-efficient and often with long lifespan. Robust construction. |
New installations or complete renovations where durability and minimal maintenance are required. |
| For separate LED tubes (T8) |
Suitable for one or two separate 150cm T8 LED tubes. Flexible in light color and output by swapping tubes. |
Renovations of existing fluorescent installations, where you wish to retain the option of replacing the light source. |
Practical installation advice for 150cm mounting rails
Installing a 150cm LED tube mounting rail is generally straightforward, but specific points of attention are crucial for safety and optimal operation. It is always advisable to consult a certified electrician if in doubt.
Preparation for installation
-
Turn off the power: For your safety, this is the most important step. Switch off the power at the distribution board that controls the relevant lighting circuit. If necessary, remove the fuse or switch off the residual current device.
-
Check the existing situation: If you are replacing an old fluorescent fixture, remove the old lamp and fitting. Check if the existing wiring is in good condition.
-
Determine mounting location and mark: Determine the exact position of the mounting rail. Use the fixing points of the fixture to mark holes on the mounting surface (wall or ceiling).
Connecting and mounting the 150cm mounting rail
-
Open the fixture: Remove the cover from the mounting rail. With some models, you must first carefully remove the aluminum support plate with the LED units by pressing down on the retaining clips. Do not touch the LED modules directly.
-
Connect wiring: Feed the power cable through the dedicated cable entry (often with a PG gland for watertight closure). Connect the phase wire (brown), neutral wire (blue), and earth wire (yellow/green) to the appropriate terminals inside the fixture.

-
Through-wiring (if applicable): Many 150cm mounting rails are suitable for through-wiring, meaning you can connect several fixtures in series to one power point. Use the extra terminals or connection points within the fixture to loop the wires to the next fixture. For watertight fixtures, ensure all connection points are properly sealed.
-
Mount the fixture: Use the provided mounting materials (screws, plugs) to securely attach the mounting rail to the wall or ceiling. Ensure the fixture is level.
-
Insert the LED tubes (if applicable): If you have a fixture for separate tubes, insert the 150cm LED tubes into the fittings.
-
Close the fixture: Replace the cover and ensure all seals (for watertight models) are properly positioned.
-
Turn the power back on: Switch the power back on at the distribution board and test the lighting.
