In most cases, warehouses and factories use cool burning fluorescent lights in the areas as the bulbs will not need to be replaced as often, they reduce power consumption, and produce only minimal heat. Halogen lights on the other hand provide glare-free lighting, which may be best in rooms where computers are used or employees are working at desks.
As you are installing lighting systems in your commercial building or office you should consider sensor lighting for any room that is not needed all the time. These rooms can include the warehouse, break rooms, offices, and bathrooms. In these rooms, most employees always forget to turn off lights when they leave the bathroom or any other room, especially when carrying supplies from the warehouse. If you have sensor lighting in these areas, you will actually save money as the lights will come on automatically when someone enters and turn off automatically when they no longer sense movement for a few minutes.
