A phenomenon when replacing some incandescent lamps by LED lamps or by complete LED lamps with permanently installed LEDs is a permanent short flashing light (flashing) or a constant slight glow of the new LED lamps. read more

The light color describes the inherent color of the light of a lamp. It is measured as color temperature in Kelvin (K). read more

In lighting technology, the term describes the decline of luminous flux in LEDs. This process normally occurs extremely slowly and only becomes noticeable after a very large number of operating hours for old LEDs. The service life specification of 50,000 hours for LEDs takes degradation into account: Although the light-emitting diodes shine longer, their luminosity is noticeably lower after more than 50,000 hours of operation. 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

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
