Lamps & Bulbs – FAQ
How do I find the right LED equivalent for an old incandescent?
Compare by lumens: 25 W incandescent → approx. 250 lm (LED approx. 3 W), 40 W → 470 lm (LED approx. 5 W), 60 W → 806 lm (LED approx. 8 W), 75 W → 1,055 lm (LED approx. 11 W), 100 W → 1,380 lm (LED approx. 14 W). Base must be identical or use an adapter.
What does the Kelvin number on the packaging mean?
The Kelvin number describes the light colour: 2,700 K = warm white (cosy, living areas), 3,000 K = warm white (retail, hospitality), 4,000 K = neutral white (office, industry), 5,000–6,500 K = daylight (lab, inspection). Further details: .
Can LEDs and halogen lamps be used on the same circuit?
Yes – both work on 230 V AC. For dimmer operation: use an LED-compatible dimmer, as conventional triac dimmers can cause LED flickering. Observe the dimmer's minimum load requirements.
Which lamps are suitable for outdoor use?
LED lamps with IP rating ≥ IP44 for covered outdoor areas, IP65+ for exposed locations. Halogen lamps in suitable outdoor luminaires possible. Discharge lamps (HQI/sodium) for area and street lighting. No incandescent lamps for outdoor use below 0 °C.
