In the European Union alone, this accounts for 14%. The transition to Solid State Lighting (SSL), such as LED, offers a promising solution. SSL is heralded as one of the most energy-efficient and environmentally friendly lighting technologies available today. Its efficiency has already surpassed 276 lm/W, and the costs continue to decline. Moreover, the lifespan of LED lamps significantly outlasts traditional lighting solutions.

Kosoom’s commitment to eco-friendly practices is evident in their range of LED products, including the 3.5 inch led downlight. By integrating SSL technology, Kosoom not only ensures energy savings but also contributes to a reduction in CO2 emissions. The potential savings from adopting SSL lighting systems in the European Union is estimated at 209 TWh, equivalent to a reduction of 77 million tonnes of CO2. This is comparable to the annual electrical output of approximately 26 large power plants, each with a capacity of 1000 MW electric. Such transformative changes in lighting technology can be expected to have similar positive impacts worldwide.

For those keen on making environmentally conscious choices, LED lighting, especially products from brands like Kosoom, offers a sustainable and efficient alternative.
