Starlicht fluorescent tubes sit in the traditional T8 linear part of the Starlicht portfolio – the same brand that appears on their wall and ceiling fittings and basic batten luminaires. Many of those luminaires are supplied “ready to use” with a Starlicht fluorescent tube pre-installed, typically 18 W or 36 W T8 G13.

In distribution, you’ll usually find Starlicht fluorescent tubes as:

classic 15 W / 18 W / 36 W T8 lamps,
neutral or warm white triphosphor versions (830, 840),
used both as spare lamps and as the default tube inside Starlicht-branded fixtures.

For many sites these tubes are a maintenance tool: they keep existing T8 lines and Starlicht luminaires running until it makes sense to move the installation to LED.

Construction and Light Quality of Starlicht Fluorescent Tubes

Starlicht fluorescent tubes follow the standard T8, G13, low-pressure fluorescent design, so they slot straight into any compatible fitting:

T8 glass body (26 mm)
A cylindrical glass tube with an internal phosphor coating. The glass versions sold through lamp wholesalers highlight durability and consistent heat dissipation compared to plastic. Fluorescent tubes remain a practical choice in facilities where broad, even illumination and predictable service cycles are still part of the lighting strategy. For general replacements in offices, corridors and auxiliary rooms, teams often rely on straightforward, easy-fit options such as spl lighting fluorescent tubes, which cover most standard fixtures. Where consistent colour output and balanced lumen performance are required — especially in retail aisles, classrooms or shared work areas — planners frequently add dependable, long-running lines like spectrum fluorescent tubes. Industrial settings, technical rooms and locations with stricter electrical requirements tend to favour the robust, conformity-focused designs of schrack fluorescent tubes for stable long-hour operation. And for cost-sensitive refurbishments or facilities with frequent replacement intervals, procurement teams usually round out their stock with practical, budget-efficient units such as rex light fluorescent tubes.
G13 bi-pin caps
Two metal pins at each end, the universal interface for T8 luminaires – battens, trunking, recessed grid fittings, waterproof housings, and Starlicht’s own basic wall/ceiling lights.
Low-pressure discharge system
Inside the tube is an inert gas plus a very small quantity of mercury. Once the lamp starts, an electric arc produces UV, which the phosphor converts into visible light. That’s why Starlicht fluorescent tubes give a wide 360° glow rather than a concentrated beam.
Triphosphor coating and colour
Starlicht fluorescent tubes are sold in standard colour codes such as 830 (3000 K warm white) and 840 (4000 K neutral white) – for example, 15W/830 and 18W/840 tubes clearly marked as Starlicht T8.

In practice this means:

CRI around 80, good enough for offices, shops and back-of-house.
Comfortable warm or neutral white light, not harsh “blue shop” tones.
Full 360° emission for soft, uniform illumination in opal diffusers and open battens.

Assortment Overview of Starlicht Fluorescent Tubes

The Starlicht fluorescent tubes range is focused on the most widely used T8 sizes – no giant catalogue, just the SKUs that really move.

Core T8 Starlicht Fluorescent Tubes

From wholesale and fixture listings you can identify at least these key products:

15W/830 T8 Starlicht
- Approx. 450 mm length, 26 mm diameter, G13.
- 3000 K warm white (code 830).
- Sold as a dedicated Starlicht fluorescent tube, marked in B2B systems as “in stock / discontinued” – ideal for short wall/ceiling lights and compact battens.
18W/840 T8 Starlicht, 60 cm
- 18 W, G13, 600 mm length.
- 4000 K neutral white (code 840), around 1000–1999 lm depending on spec.
- Frequently supplied inside Starlicht BASIC and ECOLINE luminaires as the standard tube.
36W T8 Starlicht, 120 cm
- 36 W, G13, 1200 mm length.
- Neutral white 4000 K tube giving roughly 2600–2700 lm when used in Starlicht 4 ft luminaires.

Some markets also show Starlicht 36W T8 tubes sold separately or as part of older ceiling fixtures, often now marked EOL (end of life) but still in stock.

So in real-world projects, Starlicht fluorescent tubes typically mean:

15 W × 450 mm – short fittings,
18 W × 600 mm – corridor and small-room luminaires,
36 W × 1200 mm – 4 ft general lighting.

Where Starlicht Fluorescent Tubes Are Used

Because they follow universal T8 dimensions and caps, Starlicht fluorescent tubes can be used in any compatible T8 fitting – but they are especially common in:

Starlicht BASIC and ECOLINE wall/ceiling lights
- Supplied from factory with 18 W or 36 W T8 tubes, 4000 K neutral white, for corridors, stairwells, garages and utility spaces.
Offices and small retail
- 18 W and 36 W Starlicht fluorescent tubes in standard battens and recessed fittings where at least part of the installation is built around Starlicht luminaires.
Residential and light-commercial common areas
- Parking levels, basements, laundry rooms and storerooms using simple T8 lights: neutral white 840 tubes are a good compromise between comfort and visibility.
Service and technical spaces
- Plant rooms, workshops, store corridors – places where robust, inexpensive tubes are more important than ultra-high efficiency.

In these environments, a reliable, brand-recognised T8 tube is often preferred over random “white box” lamps, because light colour, length and quality are predictable and easy to reorder.

How to Select Starlicht Fluorescent Tubes for Your Project

Choosing Starlicht fluorescent tubes doesn’t have to be guesswork. A quick, structured approach keeps things tidy and technically correct.

1. Confirm Type, Wattage and Length

All current Starlicht fluorescent tubes in this context are T8, 26 mm, G13. The key is to match wattage and length to the fitting:

15 W → ~450 mm
18 W → 600 mm
36 W → 1200 mm

Read the old tube’s marking (e.g. “15W/830 T8 Starlicht”) or the luminaire label (“1 × 18 W T8”), then choose the same from the Starlicht range.

2. Match Colour Temperature to the Space

Within Starlicht fluorescent tubes, you’ll typically see:

830 – 3000 K warm white
- Softer, more “domestic” feel; good for residential common areas, hotels, quieter corridors.
840 – 4000 K neutral white
- Clean, neutral light; ideal default for offices, stairwells, shops, garages and technical spaces.

Keep one colour temperature per visual zone. Mixing 830 and 840 in the same run of luminaires makes the installation look patchy.

3. Check Ballast and Control Gear

Starlicht fluorescent tubes are standard T8 lamps, so they work with:

magnetic ballasts + starters sized for the correct wattage,
many T8 electronic ballasts designed for 15/18/36 W tubes.

Always check the fitting’s label. A luminaire marked “1 × 36 W T8” must not be loaded with a different wattage, even if another tube physically fits. Wrong wattage can cause:

poor starting and flicker,
overheating of ballasts and lampholders,
reduced tube life.

4. Plan for Lifetime and Maintenance

Typical triphosphor T8s in this segment run around 10,000–20,000 h under normal conditions. That means:

circuits running 12 h/day will reach economic replacement in roughly 2–4 years,
for high-visibility areas, group relamping with fresh Starlicht fluorescent tubes keeps light levels and colour uniform.

Safety, Lifetime and Handling of Starlicht Fluorescent Tubes

Even with a simple product like Starlicht fluorescent tubes, a few basics make a big difference:

Safe installation
- Isolate power before working on fittings.
- Support the tube with both hands and rotate gently in the G13 lampholders; don’t twist against the glass.
Thermal limits
- Never exceed the luminaire’s maximum lamp wattage – T8 ballasts and housings are designed for specific loads.
- Keep diffusers and housings reasonably clean so gear and tubes can cool correctly.
Mercury and recycling
- Like all fluorescent tubes, Starlicht fluorescent tubes contain a small amount of mercury. At end of life, they must go to lamp/WEEE recycling, not general waste.
Signs of end-of-life
- Darkened tube ends, pinkish start-up, and repeated re-striking are normal signs that the tube is at the end of its useful life and should be replaced.

Handled correctly, you can expect Starlicht fluorescent tubes to deliver their rated life with stable colour and output.

Procurement Strategy for Starlicht Fluorescent Tubes

For wholesalers, facility managers and installers, it’s easiest to treat Starlicht fluorescent tubes as a small, standardised set in your conventional lamp portfolio:

Define a core matrix
- 15W/830 T8 Starlicht for short warm-white fittings.
- 18W/840 T8 Starlicht 60 cm for most 600 mm neutral-white luminaires.
- 36 W T8 Starlicht neutral white for 4 ft battens and Starlicht ECOLINE/BASIC fixtures.
Order strictly by EAN / MPN
- For example, the 15W/830 T8 Starlicht carries a clear EAN and manufacturer code; using these in BOMs ensures you always get the same wattage, length and light colour in future orders.
Use Starlicht fluorescent tubes where they make sense
- Keep them for healthy T8 installations and for Starlicht luminaires that are mechanically sound.
- Combine them with LED upgrades elsewhere – for example, swapping only high-hour rows to LED while maintaining low-use areas with Starlicht fluorescent tubes as long as the economics make sense.

Used like this, Starlicht fluorescent tubes become a stable, predictable component in your lighting strategy – ideal for keeping T8 infrastructure and Starlicht luminaires working reliably, while you phase in LED exactly where and when it delivers real value.м
