Lamps & Bulbs
Lamps and bulbs are electrical consumers that generate light through chemical or physical processes. The range covers six technologies: LED lamps (retrofit and specialist), halogen lamps (mains/low-voltage), fluorescent lamps (energy-saving, tubes, compact), discharge lamps (HQI, HQL, sodium/mercury vapour), incandescent lamps (specialist, decorative) and socket adapters for retrofit conversion. Always check the base designation and wattage when purchasing – both are unambiguously assigned to each lamp type. Colour temperature (Kelvin): Light colour is specified in Kelvin (K) and describes the white tone of the light. Low Kelvin values (2,700 K) produce warm, yellowish light; high values (6,500 K) produce cool, bluish daylight. Further info: . Luminous flux (lumens) instead of watts: Since the phase-out of incandescent lamps, brightness is compared in lumens (lm), not watts. A 60 W incandescent equals approx. 806 lm; an 8 W LED delivers the same brightness using 85 % less power. Colour rendering (CRI/Ra): The CRI value (80+ = good, 90+ = excellent) indicates how naturally colours appear under the light – important for retail, display and medical applications. LED Energy Comparison: Watts vs. Lumens Base designations – the most common: E27 (Edison screw, standard household lamp), E14 (small Edison screw, candle and drop lamps), E40 (mogul base for industrial luminaires and street lighting), GU10 (bayonet pin base, 230 V, recessed spotlights), GX5.3/MR16 (bi-pin low-voltage, 12 V), G13 (T8 fluorescent tube), G5 (T5 tube), R7s (linear lamp/floodlight). Matching socket adapters for retrofit conversion: socket adapters. Further reading: .

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.
