FAQ
Which E27 LED lamp replaces a 60 W incandescent?
An LED lamp with approx. 8 W and 806 lumens is equivalent to a classic 60 W incandescent at identical brightness. For warm white light: choose 2700 K or 3000 K.
Are all E27 LED lamps dimmable?
No – only models with explicit dimmer labelling on the packaging are dimmable. For dimmer installations: use TRIAC-compatible LEDs and a suitable trailing-edge dimmer.
Which colour temperature is suitable for offices?
4000 K neutral white is considered optimal for concentrated work. 3000 K is used in modern office concepts with a warm character. For daylight simulation: 5000–6500 K.
Can I use E27 LED lamps in outdoor luminaires?
Only with luminaires of protection class IP44 or higher. Always check the permissible ambient temperature of the lamp – some LED lamps are only approved for indoor use.
How much does an E27 LED lamp save per year?
With 6 h/day operation and EUR 0.30/kWh, an 8 W LED saves approx. EUR 11 per year compared to a 60 W incandescent. For 100 lamps in operation: approx. EUR 1,100 less in electricity costs annually.
