T8 Fluorescent Tube G13 14W 580lm 4000K – 361 mm, special size, natural white

Special length 361 mm — check luminaire dimensions

This is slightly longer than the most common 14W T8 standard length (360 mm). A 1 mm difference usually does not affect installation, but some precisely measured luminaires may be sensitive:

• In most luminaires, 361 mm fits directly into a 360 mm holder
• Precisely measured luminaire housings (e.g., advertising luminaires, vintage fixtures) may require an exact dimension
• Measure the length of your existing fluorescent tube before ordering if you have doubts

Typical applications

• Older furniture luminaires — under-cabinet kitchen lights, workbench lights
• Advertising luminaires — small light signs, product display luminaires
• Safes and display cabinets — small exhibition spaces and shops
• Older interior lighting fixtures — where a special-length tube is original
• Maintenance of older systems — when current fluorescent tubes burn out

T8 vs T5 — do not confuse

A T8 fluorescent tube has a diameter of 26 mm and a G13 base. Do not confuse it with T5 fluorescent tubes, which are thinner (16 mm) and use a G5 base. These are not interchangeable.

Requires a ballast or electronic control gear

A T8 fluorescent tube needs either a traditional ballast and starter or an electronic control gear (EVG / HF) to function. Check your luminaire before purchasing to see which system is in use – both are compatible with this fluorescent tube.

If needed, compatible control gear can be found in the Electrical Supplies → Control Gear/Ballasts category.

Contains mercury — recycling is important

Like all fluorescent tubes, this one contains a small amount of mercury, which is harmful to the environment. At the end of its lifespan, the fluorescent tube must be recycled according to the WEEE directive:

• Do not put the fluorescent tube in mixed waste
• Take the end-of-life tube to the nearest WEEE collection point (recycling centers, electrical supply stores, hardware stores)
• Do not break the fluorescent tube during transport – mercury vapor is harmful to health

EU EcoDesign Restrictions

The EU EcoDesign directive 2019/2020 restricts the sale of T8 fluorescent tubes for new systems starting from August 25, 2023:

• Allowed: maintenance of existing luminaires, replacement of old burnt-out lamps
• Recommended: long-term modernization of systems to LED alternatives

For special-length T8 fluorescent tubes (like this 361 mm), a comparable quality LED alternative may not be immediately available – in such cases, continued use of the fluorescent tube is justified for the maintenance of an existing luminaire.

Installation Checklist

1. Check that the luminaire has a T8 G13 base (not T5 G5)
2. Measure the space between the luminaire holders and check that 361 mm fits
3. Check that the luminaire's ballast or control gear is compatible with 14W power
4. Install with power off — turn the lamp into place
5. Turn on the power — the fluorescent tube will reach full power in about 30 seconds
6. At the end of its life, recycle according to the WEEE directive
