Osram LUMILUX T8 G13 15W Fluorescent Tube 2700K 950lm – 438 mm, warm white

T8 G13 base — compatibility with traditional luminaires

This is a T8 fluorescent tube with a G13 base, which is the most common traditional fluorescent tube size. It fits directly into T8 luminaires that have either a traditional ballast + starter or an electronic control gear (EVG / HF). The length of 438 mm corresponds to the standard length of a 15W T8 fluorescent tube.

2700K warm white — a rarity in the T8 category

This is one of the rarer 2700K T8 fluorescent tubes — the hue matches a traditional incandescent bulb and is especially suitable for ambient lighting and home use:

• General household lighting — kitchen cabinet lights, bathroom downlights
• Restaurants and cafes — warm atmospheric lighting
• Hotels and accommodation facilities — cozy lighting in rooms
• Older decorative luminaires — where a warm tone suits the aesthetic of the luminaire

If you want a colder white (e.g., 4000K or 6500K), please explore our selection in the T8 G13 Fluorescent Tubes category.

Premium LUMILUX® series — high color rendering

Osram's LUMILUX® series is a premium range of fluorescent tubes with a color rendering index (CRI) of 80–89 — significantly better than basic fluorescent tubes (CRI 40–59). In practice, this means colors appear more natural in the illuminated space, which is important, especially in households, restaurants, and areas where pleasant lighting is desired.

Requires a ballast or electronic control gear

A T8 fluorescent tube requires either a traditional ballast and starter or an electronic control gear (EVG / HF) to operate. Check the luminaire before purchase 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 product contains a small amount of mercury, which is harmful to the environment. At the end of its lifespan, the fluorescent tube must be recycled in accordance with the WEEE directive:

• Do not dispose of the fluorescent tube in general 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

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.

EU EcoDesign Restrictions

The EU EcoDesign Directive 2019/2020 restricts the sale of T8 fluorescent tubes for new installations from August 25, 2023. This means:

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

If you want to modernize your luminaire to LED, check out our selection in the T8 LED tubes category — energy savings of approximately 50% and a lifespan up to 4 times longer.

Installation checklist

1. Check that the luminaire is T8 G13-based (not T5 G5)
2. Check that the lamp length of 438 mm fits the luminaire
3. Check that the luminaire's ballast or control gear is compatible with 15W power
4. Install with power disconnected — turn the lamp into place
5. Turn on the power — the fluorescent tube will reach full brightness in about 30 seconds
6. At the end of its life, recycle according to the WEEE directive
