  • Milloin valaisimeen voi vaihtaa LED-lampun – ja milloin ei?
    November 3, 2025 Lumenled Oy

    When can you replace a lamp with an LED bulb – and when not?


    Situation Can the LED be replaced directly?
    E27/E14 incandescent lamp ✅ Yes
    230V halogen spotlight ✅ Yes
    12V halogen lamp with transformer ⚠️ Only with LED compatible transformer
    Fixed LED light ❌ No
    Fluorescent lamp ⚠️ Depends on the type of lamp


    In most cases, an LED bulb can be easily and safely replaced, saving you energy immediately. However, if your light fixture has an old transformer or special components, it is worth checking compatibility before replacing.
