1. LED and halogen: Differences in light technology
The halogen has long since been accepted as a slightly more cost-effective successor for the traditional incandescent light bulb, which was phased out and step-by-step been taken off the market entirely since 2009. Halogen lamps with their very similar warm white light and the fact that they were dimmable, soon replaced the old standard light bulbs in many homes.
But there was another light option that emerged at the same time: LED. Unlike halogen lamps, LEDs (or Light-Emitting Diodes) are not so-called thermal radiators that generate light with matching heat.
At first, LED lamps were undesirable because of their higher price. In 2016, however, the EU prohibited the sale of halogen lamps in the standard E27, E14 and other base versions to push the introduction of modern LEDs into households.
