Ledvance LEDTUBE T5 AC Performance G5 11W 849mm – direct 230V, replaces 21W

NOT compatible with HF ballasts — requires luminaire modification

This is an AC-model LED tube designed to operate directly on 230V mains voltage. Old T5 fluorescent fixtures usually contain an electronic ballast (HF/ECG) that must be bypassed or removed before installing this LED tube.

Important: installation must always be performed by a professional electrician who:

• Bypasses or removes the old HF ballast
• Wires the luminaire holders directly to the 230V mains
• Ensures that all wiring is safe and compliant with standards
• Provides the end user with documentation of the modifications

If the fixture was previously an HF model, the electrician is responsible for all technical and safety consequences following the rewiring.

AC vs HF — when to choose which?

• AC model (this one): suitable for new installations and renovations where the old ballast or driver is to be removed. More cost-effective in the long run, as the ballast does not consume extra energy.
• HF model: suitable for existing HF luminaires where you want to avoid rewiring. See our range in the T5 LED tubes category.

Replaces a 21W T5 fluorescent tube

This 11W LED tube is equivalent in luminous efficiency to a traditional 21W T5 fluorescent tube. The energy saving is approximately 48 %, and the service life of the LED tube is up to 50,000 hours (compared to 12,000–24,000 hours for a traditional fluorescent tube). The length of 849 mm corresponds to a standard 21W T5 fluorescent tube, so the lamp fits the same fixture holders.

Shatter protection — for food and healthcare use

The lamp's glass tube is protected by a special PET coating that contains glass shards if the lamp breaks. This makes the lamp suitable for spaces where breakage could pose a health risk:

• Food industry and processing (HACCP regulations)
• Restaurant kitchens and bakeries
• Meat processing plants
• 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). In practice, this means:

• In office use, it does not cause eye strain or headaches
• In production facilities, it does not cause a stroboscopic effect, which can make rotating machinery visually dangerous
• Suitable for long-term use in all professional settings

Precise color consistency — ≤ 5 SDCM

Color consistency (SDCM, Standard Deviation of Color Matching) is ≤ 5, which is a premium level. When multiple lamps are installed side-by-side (e.g., office ceiling or supermarket lighting), their color shade is very consistent — there are no visible differences between different lamps. This is an important quality metric for professional use.

Limited outdoor use

The lamp's protection class is IP20 (indoor use), but outdoor use is possible in moisture-protected luminaires (IP44 or better). The operating temperature range of −20…+45 °C covers all Finnish conditions.

Not suitable for emergency lighting

This lamp is not certified for emergency lighting use — it does not work with backup battery systems. If you need an LED tube suitable for emergency lighting, see the Bailey Ecoplus T5 LED HF models in our collection.

Installation checklist

1. Check that the luminaire has a T5 G5 base (pins 5 mm apart)
2. Check that the old HF ballast can be removed or bypassed
3. Check that the lamp length of 849 mm fits the luminaire
4. Book an electrician for the installation — do not attempt to rewire yourself
5. The electrician connects the luminaire directly to the 230V mains
6. Install the LED tube into the luminaire holders
7. Switch the power on and check the operation
