What is Troffer

A troffer is a type of lighting fixture commonly used in interior spaces such as office buildings, retail stores, warehouses, and educational or medical facilities. It is designed to be recessed into the ceiling, providing general illumination for the area. Troffers are typically rectangular in shape and come in various sizes, with the most common dimensions being 1×4, 2×2, and 2×4, referring to the length and width of the fixture in feet.

Troffers are often paired with fluorescent lamps, such as T12 and T8 lamps, although the context suggests that LED lamps can also be used. LED lamps offer greater energy efficiency and longevity compared to fluorescent lamps. Troffers are known for their ability to evenly distribute light and minimize glare, creating a comfortable and well-lit environment.

These fixtures are commonly found in commercial and industrial settings, where a uniform and consistent lighting solution is required. They are often installed in a suspended ceiling grid system, allowing for a seamless integration with the surrounding architecture. Troffers can be equipped with various control options, such as dimming capabilities, occupancy sensors, and daylight harvesting systems, providing further energy savings and customization of lighting levels.

Frequently Asked Questions

How Far Apart Should Troffer Lights Be

To determine the appropriate spacing for troffer lights in bedrooms, kitchens, and living rooms, it is recommended to follow the ceiling height rule of thumb. This involves dividing the height of the ceiling by 2 and using that measurement as the spacing between the lights. For instance, if the room has 8-foot high ceilings, the troffer lights should be spaced approximately 4 feet apart.
