NBB Bohemia is a Czech specialist wholesaler and manufacturer focused on light sources and luminaires – linear fluorescent lamps, compact fluorescents, high-pressure discharge lamps and now LED systems. Their catalogue splits linear fluorescent lamps into T5, T8, circular, ultraviolet, aquarium and food-light lines. Fluorescent tubes remain a dependable option for facilities that prioritise broad, consistent illumination and long operational lifetimes. For large offices, public buildings and educational spaces, planners often begin their specifications with the stable, high-performance ranges offered by osram fluorescent tubes. Routine replacements in administrative zones, workshops and transitional areas are frequently handled with straightforward, compatibility-friendly products such as nova light fluorescent tubes. Design-oriented interiors — hospitality halls, modern retail ceilings, open-plan workspaces — sometimes integrate clean, visually balanced solutions from nordlux fluorescent tubes to maintain a cohesive lighting profile. High-duty environments where luminaires operate for extended hours, including logistics spaces and industrial facilities, typically rely on rugged, long-life options like nordeon fluorescent tubes. Installations requiring close alignment with British electrical standards or legacy control systems often complete their specification with conformity-focused models such as newlec fluorescent tubes.

Within that structure, NBB fluorescent tubes are mainly the special-purpose lines sold under the NBB brand itself:

Blacklight Blue UVA tubes (T5 and T8),
UV-C germicidal tubes (T5 and T8),
selected EQ-type T5 linear tubes for general white light.

Standard white T5/T8 tubes in the NBB catalogue are often branded NARVA or NORDEON, but the special effects, germicidal and some EQ variants carry the NBB Bohemia logo and are treated as NBB fluorescent tubes by distributors and project buyers.

Construction and Optical Characteristics of NBB Fluorescent Tubes

Most NBB fluorescent tubes are classic low-pressure discharge lamps:

Tube geometries
- T8: Ø26 mm glass tube, G13 cap, lengths like 590 mm for 18 W Blacklight Blue.
- T5: Ø16 mm glass tube, G5 cap on EQ and UV-C variants.
Discharge system
- Inert gas + a small amount of mercury produces UV radiation when the lamp is driven by an appropriate ballast.
- The inner coating and glass type control what leaves the lamp: UVA “Blacklight Blue”, UV-C 254 nm germicidal, or broad-spectrum white.
Example: FL T8/G13 18W Black Light Blue NBB
- Type: T8 linear fluorescent, G13 base, model “8-073”.
- Nominal wattage: 18 W, operating at ~59 V, 0.36 A.
- Length and diameter: 590 mm × Ø26 mm, 360° beam angle.
- Spectrum: UVA Blacklight Blue, dominant wavelength 370 nm, colour code 073.
- Service life: 20 000 h rated, with lamp survival factor 50% at 20 000 h.
- UVA lumen maintenance: ~80% at 2 000 h, ~50% at 8 000 h – typical for special-spectrum lamps.
- Mercury content: around 8 mg, energy class G under current regulation.
Ballast requirements
- NBB explicitly states that all fluorescent tubes require a matching ballast, and the ballast choice has a major impact on lifetime.
- Direct connection to mains without ballast destroys the lamp; frequent switching (intervals < 20 min, e.g. motion sensors) is discouraged because it significantly shortens lamp life.

So, technically, NBB fluorescent tubes behave like well-specified T5/T8 lamps, but they’re tuned for non-standard spectra and specialist roles, not generic office lighting.

Assortment Overview of NBB Fluorescent Tubes

NBB Fluorescent Tubes – Blacklight Blue (UVA)

Under Ultraviolet → Blacklight Blue → T8 Blackligh Blue, NBB offers a full small ladder of Blacklight Blue fluorescent tubes, all branded NBB:

FL T8/G13 18W Black Light Blue – 117106000
- 18 W, 590 mm, Ø26 mm, G13 base, 20 000 h lifetime.
- UVA Blacklight Blue, 370 nm peak, designed for studios, clubs and discotheques.
FL T8/G13 36W Black Light Blue – 117107000
- 36 W T8, same spectrum, longer tube for higher radiant flux.
LT 58W T8/073 Blacklight Blue NBB – 117108000
- 58 W T8, 1500 mm, colour 073, highest UVA output in the series; the Heureka listing describes it specifically as a Blacklight Blue T8 UVA tube with 20 000 h service life.

There is a T5 Blacklight Blue branch as well (shorter T5 tubes with the same UVA effect), so an installer can keep the same spectral look in both T5 and T8 luminaires.

NBB Fluorescent Tubes – UV-C Germicidal T8

Another NBB-branded pillar is UV-C germicidal T8 tubes, found under Ultraviolet → UV-C T8 germicidal:

LT-T8 15W/UVC NBB – 15 W, T8, 254 nm UV-C, for compact disinfection systems.
LT-T8 18W/UVC NBB – 120106010 – “Germicidní lineární zářivka T8 UVC 254 nm”, NBB brand, 18 W T8 tube.
LT-T8 30W/UVC NBB – 120107000 – 30 W, T8, 254 nm UV-C for larger air or surface disinfection chambers.

These are quartz or special-glass UV-C emitters with almost no visible light output, tuned to the 254 nm germicidal peak. They are used inside professional disinfection devices, not as open-room luminaires.

NBB Fluorescent Tubes – UV-C T5 and Compact Germicidal

The same concept is available in slimmer and compact forms:

UV-C T5 germicidal – T5 linear UV-C tubes for compact luminaires or tight disinfection chambers.
UV-C G23 / 2G11 compact lamps – short compact fluorescents used in sterilisation devices and OEM air cleaners.

They’re all grouped under UV-C germicidal in the NBB catalogue, which makes it easy to standardise across several luminaire types.

NBB Fluorescent Tubes – T5 EQ General-Lighting

Beyond UV, there are EQ (Efficient output) T5 linear tubes that NBB Bohemia sells under its own name:

A directory snippet describes “lineární zářivka LT T5-EQ from NBB Bohemia, G5 base, 21 W, 2100 lm, natural white light”, explicitly listed as dimmable; that’s a 16 mm T5 lamp designed for general white-light applications.

These sit in Linear Ø16 mm T5 → Efficient output (EQ) and act as slim, efficient white-light tubes for T5 fixtures in offices, corridors and technical rooms.

Where NBB Fluorescent Tubes Are Used

Because the range leans heavily toward special spectra, NBB fluorescent tubes are typically used where standard tri-phosphor tubes are not enough.

Entertainment and stage lighting (Blacklight Blue)
- FL T8/G13 18W, 36W and LT 58W T8/073 Blacklight Blue are explicitly marketed for studios, clubs and discotheques, producing strong fluorescence from white fabrics, UV-reactive paints and security markings.
Decorative and effect lighting
- Blacklight Blue tubes are also used in theme parks, bowling alleys, escape rooms, and museum installations for “hidden ink” or glowing graphic effects. NBB highlights them as disco effects and decorative lighting in the product texts.
Air, surface and water disinfection (UV-C germicidal)
- LT-T8 UVC tubes at 15 W / 18 W / 30 W serve as the UV emitter inside closed germicidal fittings, air ducts, flow-through UV units and sterilisation boxes produced by NBB and OEM partners.
Technical and office lighting (T5 EQ)
- The LT T5-EQ 21 W / 2100 lm type is a neutral white, efficient T5 tube, suited for linear T5 luminaires in offices, classrooms and plant rooms that still run on fluorescent gear but need modern output and dimming compatibility.

In many real projects, NBB fluorescent tubes sit alongside NARVA and NORDEON T8/T5 lamps in the same catalogue, giving designers a complete palette from mainstream white to specialised UV and food-light applications.

How to Select the Right NBB Fluorescent Tubes

When you specify NBB fluorescent tubes, treat it as a small engineering decision rather than just picking “some UV tube”.

Match geometry and wattage

Decide T5 vs T8
- T8 → Ø26 mm, G13, typical lengths 590 / 1200 / 1500 mm.
- T5 → Ø16 mm, G5, used where luminaires are slim and shallow.
Use the luminaire rating
- If the fixture says “1 × 18 W T8”, choose the corresponding 18 W NBB fluorescent tube (Blacklight Blue or UVC) – never up- or down-lamp on a magnetic ballast.
- T5 EQ lamps must match the T5 wattage printed on the reflector or housing.

Choose the spectrum: UVA, UV-C, or white

Blacklight Blue (UVA, 370 nm)
- Use FL T8/G13 Black Light Blue or T5 Blacklight Blue when you want fluorescent effects with little visible light, e.g. club lighting, UV posters, security marks.
- These tubes are classed as “for special purposes” in their own data sheets.
UV-C 254 nm (germicidal)
- LT-T8 UVC lamps are not general lighting products. They should only be specified into certified germicidal housings with interlocks, shielding and correct safety labelling.
T5 EQ white
- For normal illumination in T5 luminaires, pick NBB T5-EQ types (e.g. 21 W / 2100 lm) in natural white – ideal when you want efficient, dimmable white light but keep existing T5 fittings.

Respect ballast and switching constraints

NBB’s own safety note is very clear for its fluorescent tubes:

Always use a compatible ballast type recommended by NBB; the wrong ballast can drastically shorten lamp life.
Never connect fluorescent tubes directly to mains – the lamps will be destroyed.
Avoid frequent on/off cycles (e.g. motion sensors with short intervals); anything under about 20 minutes per cycle is considered frequent and will reduce lifetime.

Safety and Handling of NBB Fluorescent Tubes

Because NBB fluorescent tubes include UVA and UV-C variants, safety deserves its own part.

Mercury and breakage
- NBB states that Blacklight Blue tubes contain around 8 mg of mercury and recommends ventilating the room and using protective equipment if a lamp breaks. Shards should be carefully removed and a dedicated decontamination kit used where available, especially in premises with many lamps (shops, warehouses).
- End-of-life lamps must be returned through proper lamp/WEEE recycling, not household waste.
UVA vs UV-C exposure
- Blacklight Blue (UVA 370 nm) is mainly an eye-safety and skin-dose question – install these tubes in line with entertainment-lighting guidelines and avoid staring into the lamps at short distance for long periods.
- UV-C 254 nm is strongly hazardous to skin and eyes. UVC NBB fluorescent tubes belong only in closed or shielded germicidal devices and must never be used as open-room lighting. Any specification should follow relevant safety standards and local regulations.
Temperature and burning position
- Blacklight Blue tubes are specified for ambient 35 °C for maximum output, with “any burning position” allowed. Cooling far below the optimisation point can reduce radiant efficacy.

Handled properly, NBB fluorescent tubes deliver reliable, predictable performance in their niche roles – but cutting corners on ballast choice, shielding or disposal is not an option.

Wholesale Supply of NBB Fluorescent Tubes by Bank of Lamps

For B2B buyers, Bank of Lamps can supply the full NBB fluorescent tubes assortment – from Blacklight Blue T8 UVA tubes (18 W / 36 W / 58 W, order numbers 117106000, 117107000, 117108000) to UVC germicidal T8 lamps like LT-T8 18W/UVC (120106010) and LT-T8 30W/UVC (120107000), plus selected T5-EQ white tubes.

In practice that means:

Ordering by EAN / order number for exact spectrum and wattage.
