Energy-saving lamps are artificial light sources that are similar to incandescent lamps but use less energy for the same brightness. Compact fluorescent lamps are often referred to as energy-saving lamps. Other more energy-efficient light sources are LEDs, high-pressure discharge lamps or coated halogen lamps. read more

Low voltage technology works on the 12 volt basis. Thus, in contrast to the 230 volt system, the current intensity is very high. All screw connections must therefore be tightened firmly to avoid scorching of the contact points. read more

If you do it right, cleaning a crystal luminaire is done quickly. The effort is as great as with any other light, but the effect of an occasionally cleaned crystal light is incomparably better. read more

LED technology is already very advanced, but not yet to the point where floodlight halogen lamps can be replaced. Even if it were possible in the short term to place LEDs in the form of a halogen rod in such a way that cooling and light emission are guaranteed, the luminous fluxes currently possible are too low. At present, very good LEDs can achieve luminous fluxes of around 60 lumens per watt. read more

More and more customers, guided by embellished advertising claims, are asking us about LED technology. The fact that the luminous efficacy per watt of LEDs (30-80 lumens/watt) is higher than that of incandescent lamps (13-17 lumens/watt) and energy-saving lamps (50-70 lumens/watt) is undisputed. read more
