VITOLIGHT fluorescent tubes are part of the brand’s conventional lamp range and are mainly used to keep existing T8 installations running – in shops, service areas, stairwells, warehouses and signage – without changing luminaires or control gear. They sit next to other VITOLIGHT conventional lamps in professional B2B catalogues and are offered specifically as tubular T8 G13 lamps.

Unlike many generic tubes, there are clearly defined special-purpose variants, like the Fluorescent Tube 36W T8 BLUE VITOLIGHT, used for decorative, branding or accent tasks, alongside standard white tubes for general lighting.

Construction and Technology of VITOLIGHT Fluorescent Tubes

All VITOLIGHT Fluorescent Tubes are based on classic low-pressure mercury fluorescent technology in a T8 (26 mm) glass body with a G13 bi-pin cap:

Glass tube
- T8 diameter, typically 600 mm (18 W class) or 1200 mm (36 W class) depending on wattage.
- Inner wall is coated with phosphor; in special tubes (e.g. BLUE) this coating and/or glass tint sets the output colour.
Electrodes at both ends
- Coiled tungsten cathodes with emissive coating, one at each end of the tube.
- Connected via G13 pins to the lampholder and ballast circuit.
Gas fill and mercury
- Argon/argon–krypton mix plus a small amount of mercury vapour.
- When the lamp is started, a discharge forms in the gas and excites UV light, which the phosphor converts into visible light. Fluorescent tubes are still widely specified in facilities where long, even illumination and low operating costs matter more than fixture modernisation. For everyday replacements in offices, corridors and utility areas, maintenance teams often rely on practical, easy-to-stock ranges such as zext fluorescent tubes, while broader commercial portfolios frequently standardise on the balanced, reliable output offered by viva light fluorescent tubes. Projects requiring stable colour performance or higher-grade phosphor quality — particularly retail aisles and educational spaces — often integrate long-proven lines like tungsram fluorescent tubes. For cost-controlled refurbishments, facility managers commonly choose value-oriented options such as toplux fluorescent tubes to keep maintenance predictable. And large sites with strict lighting-consistency requirements, including logistics halls and multi-Bay commercial interiors, frequently complete their specifications with the dependable, globally supported ranges from sylvania fluorescent tubes.
Phosphor system
- For white tubes: multi-band phosphors tuned to give warm, neutral or cool white.
- For coloured tubes like the 36W T8 BLUE VITOLIGHT: phosphors and/or glass designed to pass mainly blue wavelengths for signage and decorative effects.

These VITOLIGHT Fluorescent Tubes operate on conventional control gear (magnetic ballast + starter) or on compatible electronic ballasts, depending on the luminaire design. The VITO/VitoLight ecosystem even includes dedicated starters (S10, S2) for 4–65 W and 4–22 W fluorescent tubes, which is exactly the power range these T8 lamps sit in.

Assortment of VITOLIGHT Fluorescent Tubes

In professional B2B catalogues, VITOLIGHT Fluorescent Tubes appear as a dedicated category under VITOLIGHT conventional lamps and “Fluorescences tubulāras spuldzes / Fluorescent Tubes T8”.

Within that family, you can expect three main groups:

VITOLIGHT Fluorescent Tubes – Standard White T8

Although the product page we see is focused on a coloured tube, the category itself is labelled for T8 fluorescent lamps, so the usual backbone of the range is:

18 W T8 G13 (approx. 600 mm) – for compact luminaires, small offices, back-of-house and corridors.
36 W T8 G13 (approx. 1200 mm) – the classic “4-foot” tube for many ceilings, shops and utility areas.

These would typically be available in common colour temperatures (e.g. 3000 K warm white, 4000 K neutral, 6500 K cool) and standard lumen packages in line with T8 norms, making them drop-in replacements for existing T8 installations.

VITOLIGHT Fluorescent Tubes – Special Colour T8 (BLUE and Others)

One clearly documented SKU is:

Fluorescent Tube 36W T8 BLUE VITOLIGHT
- T8 diameter, G13 base, 36 W power
- Blue light output for decorative lighting
- Marked as a VITOLIGHT brand product under both “Fluorescent Tubes T8” and “G13 Light Bulbs”

Special-colour VITOLIGHT Fluorescent Tubes like this are typically used for:

Architectural accents (blue coves, columns, façades)
Brand-colour backlighting for signage and displays
Atmospheric effects in bars, bowling alleys, showrooms

VITOLIGHT Fluorescent Tubes – Luminaires and Accessories Ecosystem

Vito / VitoLight also publish technical sheets for luminaires with T8 fluorescent tubes (for example, wall fixtures specified for T8 18–36 W tubes).

That means VITOLIGHT tubes are designed to integrate cleanly with:

T8 indoor/outdoor wall luminaires
Linear battens and damp-proof fittings
Exit/emergency-style luminaires and special housings

For procurement, this matters: you can standardise on VITOLIGHT Fluorescent Tubes and know they will match a family of compatible fixtures and starters in the same ecosystem.

Performance Characteristics of VITOLIGHT Fluorescent Tubes

While every SKU will have its own datasheet, you can assume typical T8 performance as a planning baseline for VITOLIGHT Fluorescent Tubes:

Power and length (T8, G13)
- 18 W → approx. 600 mm
- 36 W → approx. 1200 mm
Luminous efficacy
- Standard T8 white tubes: around 70–90 lm/W depending on phosphor and ballast type.
- Coloured tubes (BLUE): lower lm/W in white-lumen terms, because only a narrow band of the spectrum is emitted – chosen for colour impact, not maximum lux.
Colour rendering
- General-lighting whites normally around CRI 80; good enough for offices, retail and back-of-house.
- Coloured tubes like BLUE are for effect; CRI isn’t a meaningful metric there – the goal is saturated, consistent colour on surfaces.
Lifetime
- Typical rated life for good T8 tubes is 10,000–20,000 hours on appropriate ballasts; special colours often fall in a similar range when not over-switched or overheated.
Starting and warm-up
- On magnetic ballast + starter: brief preheat and flicker, then full light.
- On electronic ballast: fast, almost flicker-free starting and better lumen maintenance.

Typical Applications for VITOLIGHT Fluorescent Tubes

Because of their T8 form factor and G13 base, VITOLIGHT Fluorescent Tubes map neatly onto classic fluorescent installations:

Retail and service areas
- Ceiling luminaires, continuous rows and wall lights in supermarkets, showrooms, DIY stores.
- BLUE VITOLIGHT Fluorescent Tubes in promotional zones, entrances and brand-colour elements.
Commercial back-of-house
- Storage rooms, corridors, technical areas and workshops that already use T8 battens or trunking.
Public buildings and education
- Classrooms, libraries and circulation spaces, where maintaining existing fluorescent infrastructure is still more practical than full LED conversion.
Signage and effects
- Box signs and lightboxes sized around 18/36 W T8 dimensions.
- Decorative coves and feature lines using BLUE or other colour tubes for atmosphere.

How to Select VITOLIGHT Fluorescent Tubes for Your Installation

When you choose VITOLIGHT Fluorescent Tubes, treat it as a small engineering decision, not just “same wattage again”.

1. Confirm Tube Type, Base and Length

Tube shape: T8 (26 mm diameter)
Cap: G13 bi-pin
Length: typically 600 mm (18 W) or 1200 mm (36 W) – measure the existing lamp and check luminaire spec.

Mixing T5/T8 or wrong lengths will simply not fit or won’t start on the existing control gear.

2. Match Wattage to Gear and Luminaire Label

Use the wattage printed on the luminaire and ballast as your main reference.
18 W and 36 W VITOLIGHT Fluorescent Tubes are designed to work with ballasts rated for those powers – do not install 36 W tubes on 18 W circuits or vice versa.

3. Decide Between White and Coloured VITOLIGHT Fluorescent Tubes

White tubes – for general illumination: choose the colour temperature (3000 K / 4000 K / 6500 K) to match the surrounding lighting.
BLUE VITOLIGHT Fluorescent Tubes – for effect and branding:
- use them in signs, alcoves, coves, underbars;
- avoid using them as the only ambient light source – they distort colour perception by design.

4. Consider Ballast Type and Switching Pattern

On magnetic ballast + starter, choose tubes explicitly rated for conventional operation and use correct starters (e.g. S10 4–65 W, S2 4–22 W in the same ecosystem).
On electronic ballasts, ensure the tube is compatible and avoid excessive switching (many short on/off cycles) if you want to maximise life.

5. Keep Colour Temperature Consistent

If you specify white VITOLIGHT Fluorescent Tubes, keep one CCT per visual zone – mixing warm and cool tubes in one row looks patchy and unprofessional.

Safety, Control Gear and Environmental Notes

Fluorescent technology has a few safety and compliance points you need to respect with VITOLIGHT Fluorescent Tubes:

Hot spots and temperature
- Luminaires should provide adequate ventilation.
- Do not use higher wattage than indicated on the fitting; this can overheat ballasts and lampholders.
Starters and ballasts
- Always match starter type to tube wattage and circuit (series vs parallel). The VITO/VitoLight starter family is explicitly labelled for standard fluorescent tube ranges.
Mercury content and recycling
- Like all T8 fluorescents, VITOLIGHT tubes contain a small amount of mercury and must be treated as waste electrical and electronic equipment (WEEE) at end of life – return them to appropriate recycling points, never to mixed waste.
Handling and breakage
- Handle tubes carefully by the ends to avoid twisting the glass;
- If a tube breaks, ventilate the area and follow standard fluorescent clean-up guidance (collect fragments, avoid using vacuum cleaners directly on fine powder).

Wholesale Supply of VITOLIGHT Fluorescent Tubes

In B2B channels, VITOLIGHT Fluorescent Tubes are sold by specialist wholesalers with:

dedicated category pages for VITOLIGHT Fluorescent Tubes T8;
clear EAN/MPN codes, for example 8697451404383 for the 36W T8 BLUE VITOLIGHT;
and project-oriented pricing with validity windows (e.g. price valid until 31.12.35 on that SKU).

For professional buyers and installers, a good strategy is to:

Standardise on a short list of VITOLIGHT Fluorescent Tubes (18 W and 36 W whites, plus any special colours like BLUE you actually use).
Always order by exact EAN/MPN so replacements match the same output colour and electrical characteristics every time.
Combine VITOLIGHT tubes with compatible Vito/VitoLight starters and T8 luminaires in one BOM, simplifying maintenance and future upgrades.

Used this way, VITOLIGHT Fluorescent Tubes become a clean, controlled part of your conventional lighting portfolio – ideal for keeping T8 infrastructures operating reliably today, while you plan when and where it makes sense to migrate individual lines or entire sites to LED.
