The Ledvance LEDTUBE T5 HF Performance is a premium-level LED tube that is installed directly in place of an existing electronic HF ballast without the need for rewiring. With only 11 W of power, it replaces a traditional 24 W T5 fluorescent tube, and the shatter-protected PET coating allows for use in the food industry and facilities with specific requirements. The short 549 mm length is suitable for small furniture luminaires, shelf lighting, and advertising displays. Lifespan of up to 60,000 hours, color consistency ≤ 5 SDCM, and low flicker (EU 2019/2020).

HF model — works with electronic ballasts. Please check compatibility before ordering.

⚠ Made-to-order item

This product is made-to-order — delivery time is approximately 2 weeks from the order date. Please consider this if you need the tubes urgently.

✓ Easy replacement — no wiring changes

This HF model works directly with the existing electronic ballast. Replacing a traditional 24W T5 fluorescent tube with this LED tube is a direct lamp replacement — no rewiring by an electrician or modifications to the luminaire are required. Just check the ballast compatibility before ordering.

ℹ Also suitable for the food industry

The shatter-protected PET coating prevents glass fragments from scattering if the lamp breaks — this makes the lamp suitable for use in the food industry, restaurant kitchens, bakeries, and other spaces with hygiene requirements in accordance with HACCP regulations.

Compatibility and installation

Direct replacement — simple installation

This HF model is designed for direct replacement of an existing T5 fluorescent tube in luminaires equipped with an electronic HF ballast (EVG / ECG). Installation is:

  1. Turn off the power
  2. Remove the old T5 fluorescent tube
  3. Install the new LED tube into the same holder
  4. Turn on the power

No need to rewire or remove the choke, starter, or ballast — everything remains as is.

549 mm length — for small luminaires

This short 549 mm tube is particularly suitable for:

  • Furniture luminaires — under-cabinet lights, shelf lights, task lighting
  • Smaller office and study luminaires
  • Advertising displays and exhibition spaces
  • Smaller industrial and warehouse luminaires
  • Safes, display cabinets, and product presentation lighting

The length of 549 mm corresponds to the length of a standard 24W T5 fluorescent tube (HO model), so the lamp fits directly into the same luminaire holder.

Check ballast compatibility

Although this lamp is designed for the most common HF ballasts, not all models are 100% compatible. Check compatibility:

The most common compatible ballast brands are: Helvar, Tridonic, Osram, Philips, Vossloh-Schwabe, Ledvance.

Replaces 24W T5 fluorescent tube

This 11W LED tube corresponds in lighting efficiency to a traditional 24W T5 fluorescent tube. Energy savings are approximately 54%, and the LED tube's lifespan is up to 60,000 hours — more than double that of a traditional fluorescent tube (12,000–24,000 h). The length of 549 mm corresponds to the length of a standard 24W T5 fluorescent tube.

Shatter protection — for food and healthcare use

This lamp's glass light tube is protected by a special PET coating that keeps glass shards contained if the lamp breaks. This makes the lamp suitable for spaces where glass breakage could be a health hazard:

  • Food industry and processing (compliant with HACCP regulations)
  • Restaurant kitchens and bakeries
  • Hospitals and healthcare facilities
  • Chemical industry and laboratories

Low flicker — for office use

The lamp meets the flicker requirements of the EU 2019/2020 directive: SVM ≤ 0.4 (stroboscopic effect) and PstLM ≤ 1 (short-term flicker). This means the lamp is suitable for long-term use without eye strain or headaches.

Also suitable for low temperatures

The operating temperature of −20…+45 °C covers all Finnish conditions. The lamp turns on at full power immediately even in cold spaces, which is important for cold storage, outdoor shelters, and industrial halls.

Limited outdoor use

The lamp's protection class is IP20 (indoor use), but outdoor use is possible in moisture-proof luminaires (IP44 or better).

Not suitable for emergency lighting

This lamp is not certified for emergency lighting use — it does not work with backup battery systems.

Installation checklist

  1. Check that the luminaire has a T5 G5 base (base with 5 mm pin spacing)
  2. Check that the luminaire has an electronic HF ballast (EVG / ECG)
  3. Check ballast compatibility from the Compatibility charts
  4. Check that the 549 mm lamp length fits the luminaire
  5. Turn off the power — remove the old fluorescent tube
  6. Install the new LED tube into the same holder
  7. Switch on the power and check operation

Usein kysytyt kysymykset

Can I directly replace an old 24W T5 fluorescent tube with this LED tube?

Yes, and easily at that. This HF model LED tube is designed for direct replacement of an existing 24W T5 fluorescent tube in luminaires with an electronic HF ballast. Installation:

  1. Turn off the power
  2. Remove the old T5 fluorescent tube
  3. Install the new LED tube into the same fixture
  4. Turn on the power

No electrician or rewiring is needed — the choke, starter, and ballast remain as they are. Just check before purchasing that the luminaire has an electronic HF ballast (not a magnetic choke) and that the lamp length of 549 mm fits the luminaire.

What is a T5 HO fluorescent tube and how does it differ from a standard T5?

The T5 HO (High Output) fluorescent tube is a more powerful version of the T5 fluorescent tube, producing more light at a shorter length:

  • Standard T5: e.g., 14W = 549 mm, 21W = 849 mm
  • T5 HO (High Output): e.g., 24W = 549 mm, 39W = 849 mm — same length, but higher power and more lumens

This 11W LED tube replaces a 24W T5 HO fluorescent tube at 549 mm length. If you have previously used a 14W standard T5 fluorescent tube in the same luminaire, this LED tube will produce more light (1,550–1,700 lm vs. ~1,200 lm from a 14W standard T5).

How do I check that the HF ballast is compatible with the LED tube?

HF ballasts are not 100% compatible with all LED tubes. Verification:

  1. Open the luminaire and check the make and model of the ballast (e.g., Helvar EL2x24iCS, Tridonic PC 2x24 T5, Osram QT-FIT8)
  2. Check compatibility on Lumenled's Compatibility Tables page
  3. Or check Ledvance's official list: www.ledvance.com/low-voltage-ledlamps
  4. If the ballast is not on the list, please contact our customer service - we will help with the verification.

The most common compatible ballast brands are: Helvar, Tridonic, Osram, Philips, Vossloh-Schwabe, Ledvance. Older or rarer models may require verification.

What is the lifespan and how does it compare to a fluorescent tube?

The lifespan of this LED tube is up to 60,000 hours, which is significantly longer than traditional T5 fluorescent tubes (12,000–24,000 h).

  • With 8 hours of daily use (office, supermarket): the lamp lasts approximately 20 years
  • With 12 hours of daily use (industry, warehouse): the lamp lasts approximately 13 years
  • With 24 hours of continuous use (hospitals, 24/7 lighting): the lamp lasts approximately 6.8 years

Compared to the 24,000-hour lifespan of a 24W T5 fluorescent tube, this LED tube lasts 2.5 times longer while consuming 54% less energy. In the long run, the total cost of ownership (TCO) is significantly lower.
