The lighting fitting as a whole, which accommodates the lamp incandescent lamp, halogen lamp etc. Transformers generally consist of two coils of wire wound around an iron core. The core is made of thin sheets of iron insulated with a non-conducting material. Transformer hum occurs when magnetic forces cause the iron sheeting to vibrate. Electronic transformers work on a different principle so they never hum.

A fluorescent lamp ignites with the help of a starter only when a sufficiently high current impulse is delivered in the ballast conventional or low-loss.

HQI are more economical, for short on-periods incandescent lamps are most economical. Achieving the same illuminance on a horizontal surface like a dining freunde kennenlernen freiburg with a light fixture with indirect light emission will require a lamp of higher wattage than in a fixture with direct light emission.
For the illumination of living spaces this rule of thumb applies: Achieving an illuminance of lux with halogen lamps, requires 40 watt per sqm.
With the use of energy-saving lamps the energy consumption for lux is reduced to 10 watt per sqm.
