GU10/E27-LED: Flimmern, Brummen, Nachleuchten
Entscheidungsweg wie auf unserer französischen Seite. Bei Brandgeruch oder Verteiler: Elektriker rufen.
1 — Main symptom
- Flicker when on, especially at low dimmer setting → check dimmable marking, trailing vs leading edge, minimum load, replace incompatible dimmer.
- Buzz from dimmer or lamp → halogen-era dimmer on LED, under-minimum load, mix of dimmable and non-dimmable — use LED-rated dimmer and matched bulbs.
- Glow or flash when “off” → standby current through smart/no-neutral switch or dimmer leakage — bypass, compatible dimmable LED, or smart bulb with switch locked ON.
- Flicker at 100 % on a simple switch → loose lamp, failing driver, or bad contact in GU10 holder — try another bulb, check lampholder.
Typical fixes (from our tree leaves)
| Case | Schwierigkeit | Time | Cost |
|---|---|---|---|
| Non-dimmable LED on dimmer → swap for dimmable or remove dimmer | 1 | 5–15 min | £5–25 |
| Leading-edge dimmer + dimmable LED → trailing-edge LED dimmer | 2–3 | 20–45 min | £25–55 |
| Single low-power LED below dimmer minimum → add load or “low load” dimmer | 2–3 | 25–50 min | £10–50 |
| Smart switch without neutral + ghosting → manufacturer bypass at rose | 3–4 | 30–90 min | £4–15 parts (+ electrician) |
