For lighting large areas with high ceilings like warehouses, production environments and sports halls, Philips LED high-bay lighting is perfect. It's robust, has very good thermal conductivity and, with an IP rating of at least IP65, Philips LED high-bay lighting is resistant to dust and water. 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. Philips, of course, is one of the most trusted names in the lighting business.
