Ledvance LED high-bay lighting is robust, has very good thermal conductivity and with an IP rating of at least IP65, it's resistant to dust and water too. Ledvance LED high-bay lighting is ideal for lighting large areas that have high ceilings like warehouses, production environments and sports halls. If you're using conventional high-bay lights that have 250-watt or 400-watt gas-discharge bulbs, switching over to LED will save you approximately 50% in energy costs! What's more, due to sustainable LED technology, LED high-bay lights last up to 20 years! Buy a DALI-controllable LED high-bay light and you'll benefit from even more cost savings and an even longer lifespan. Ledvance LED high-bay lighting is excellent value for money.
