LED Tube Lights 120 cm: an Efficient Replacement

Replacing a 120 cm fluorescent tube (36W) with a 120 cm LED tube of the same length offers immediate benefits. Modern 120 cm LED tubes consume significantly less power, often between 14W and 18W, while providing similar or even higher light output. This results in immediate energy savings and contributes to a lower carbon footprint. Additionally, LED tubes are mercury-free and last much longer than traditional fluorescent tubes, reducing replacement frequency and maintenance costs.

Comparison: Old Fluorescent 120 cm (36W) vs. LED Tube 120 cm

To give a clear picture of the differences between a traditional 120 cm fluorescent tube and the LED replacement, here is a practical comparison table. This table helps to estimate the benefits when considering a switch.

Installing a 120 cm LED Tube

Installing a 120 cm LED tube in an existing fixture is generally a simple procedure. The method depends on the type of ballast present in the fixture: conventional (EM) or electronic (HF).

Type 1: Installation with Conventional Ballast (EM)

Most older fluorescent fixtures operate with a conventional ballast and a starter. When replacing with an LED tube, it is important to insert the supplied LED starter.

1. Switch off the power supply to the fixture completely for your safety.
2. Remove the old fluorescent tube.
3. Replace the old starter with the supplied LED starter.
4. Place the new 120 cm LED tube in the fixture.
5. Switch the power back on and the lamp will work.

Type 2: Installation with Electronic Ballast (HF)

Fixtures with an electronic ballast do not have a separate starter. Installing an LED tube in these is straightforward.

1. Switch off the power supply to the fixture completely for your safety.
2. Remove the old fluorescent tube.
3. Place the new 120 cm LED tube in the fixture.
4. Switch the power back on and the lamp will work.

For optimal performance and energy savings, more and more technicians are considering removing the ballast and connecting the LED tube directly to mains power (direct installation). However, this requires rewiring and should best be performed by a qualified professional.

Choosing the Right 120 cm LED Tube

When selecting the right 120 cm LED tube for your needs, other technical factors are relevant in addition to the installation method:

Luminous Output and Color Temperature

The luminous output of an LED tube is expressed in lumens, indicating how bright the lamp shines. For general lighting in offices, warehouses, or workshops, a higher lumen value is recommended.

The color temperature, measured in Kelvin (K), determines the character of the light:

• 3000K (Warm White): Suitable for areas where a cozy atmosphere is important, such as reception areas or showrooms.
• 4000K (Cool White): A functional, neutral light color, often used in offices, workshops, and warehouses where good visibility is required.
• 6500K (Daylight White): Provides a bright, stimulating environment, commonly used in laboratories or production areas where detailed work is performed.

Color Rendering and Energy Efficiency

The color rendering index (CRI) indicates how faithfully colors are rendered under the light. For most applications, a CRI of 80 or higher is sufficient. In environments where color accuracy is important, such as print shops or stores, a higher CRI is desirable.

Pay attention to the energy label of the LED tube. Although LED is generally much more efficient than traditional fluorescent lighting, there are also differences in efficiency within the LED category. A higher label (for example A, B, or C according to the new EU regulation) means a higher light output per watt.

Alternative Lighting Solutions

In addition to the 120 cm T8 LED tubes, there are also other LED lighting options suitable for similar applications, depending on the specific requirements of the space:

• LED Panels: These fixtures offer very even light distribution and are suitable for suspended ceilings, often found in offices and schools.
• Integrated LED Tube Fixtures: These are complete fixtures with built-in LED light sources. Often available in waterproof variants (IP65), suitable for damp areas or outdoor use.
• LED High Bays: For high ceilings in warehouses, factory halls, or sports halls, LED high bays provide a powerful, concentrated light beam.

The Future of T8 120 cm Lighting

With the phase-out of traditional fluorescent tubes, the 120 cm T8 LED tube has become the standard for efficient and sustainable lighting in a wide range of environments. This transition not only delivers immediate savings on energy and maintenance costs, but also contributes to responsible business operations or household management. The availability of various light colors and installation options means that there is a suitable 120 cm LED tube for virtually any situation.
