In the past, fluorescent tubes were good alternatives to incandescent lamps and halogens. But they have many disadvantages: They start slowly, flicker, make noises, have a short service life, and high energy consumption. That is why it is worth switching to LED. LEDs are not only much more efficient, but they also last up to … Read more
Who does not know it: The lamps in a luminaire never burn out at the same time. Nevertheless, we would like to continue to have sufficiently bright light. But replacing lamps that are still working sounds like unnecessary expenses and a waste of resources. But is that really it? We show you why you can … Read more
Do LED lights need to be recycled? Yes, led lights need to be recycled, and led lights are recyclable. LEDs do not belong in the household waste, they have to be recycled. They contain electronic components that are very valuable and should be recycled. These include rare earths and electronic components such as diodes and … Read more
With the use of LEDs, as with any electrical device, the lighting tends to gradually decrease. There is a standard called L80 B10 that determines the lifespan of LEDs. We will inform you what exactly this means and what you can pay attention to when choosing your LEDs. The specification L80B10 describes the time after … Read more
LEDs have a very long lifespan. LED lights last longer than incandescent, CFL, fluorescent, or other conventional lights. The average lifespan of led lights is 50,000 to 100,000 hours. An LED rated at 50,000 hours will last more than 11 years if utilized 12 hours a day. It will last 17 years if used for … Read more
Did you see light stays on dim when switch is off? Surprising, isn’t it? Why do LED lights glow dim when switched off? This is quite a common issue, especially with low-quality cheap LEDs. But, the good news is that you can easily fix the problem—and by the end of this post, you will learn … Read more
