Lensed troffers are modern light fixtures used primarily in office spaces, educational centers and hospitals, as well as other public buildings. They emit a diffuse, constant light, ideal for workspaces. Because of the lensed louver technology, they offer a non-reflexive, relaxing light, with little to no reflection on computer displays which may otherwise hinder work.
Lensed troffers are horizontal lighting fixtures and they can be installed either on the surface of the ceiling, in recessed locations or mounted on cables. Depending on the model, the housing is made of gauge cold rolled steel or extruded aluminum. The housing is further reinforced with embossments to ensure maximum durability and sturdiness. Featuring a unique doorframe design that has a mechanical light seal, the fixture does not require foam insulation (such as gaskets).
Smooth, hemmed sides and ends ensure easy and safe installation and maneuvering, while also offering a sleek look to the fixture. Light leaks are prevented with the help of specially designed light traps which are painted in matte black enamel paint. The housing is finished with ultra resistant baked white enamel paint and it is further treated with a five stage phosphate bonding process.
The hinges and latches are positive spring-loaded and the vents are finger-tip actuated. The flush steel door hinges are located on both sides, offering maximum flexibility during installation and maintenance. Safety is further ensured by specially designed earthquake sensitive integral T-bar safety clips, which come standard on all models. The T bar clips are designed to be easily adapted to any situation and can be securely attached to the ceiling system.
The lens system of the lensed troffers is composed of an 100% acrylic translucent diffuse board with a prism pattern. The lens is guaranteed to offer the best diffuse light with no shadows and blank spots. The low-profile and elegant design is ideal for restricted plenum applications.
The fixtures can be equipped with T8, T5 and T5OH lamps and instant electronic ballasts that work on 120/277V circuits and an intensity of 50Hz to 60Hz with maximum variations of +/-10%. The ballasts have a normal factor of 0.88 and use energy-saving, top efficiency F32T8 lamps with a power of 25W. The ballasts are rated A for sound-rate signals and meet all the requirements of ANSI C 82.11. The fixture features a parallel circuit type, a starting temperature of 0°F for the basic 32W lamps and as low as 60°F for the energy-saving T8 lamps.
Depending on the model and the type of mounting, the louver is available in multiple depths, from 2 inches to 5 inches. The larger models can feature up to 32 cells and can incorporate 4 lamps, while the smaller fixtures feature 10 cells and can house 1 lamp.
Lensed troffers are distinct, elegant, modern fixtures that offer relaxing and diffusing light to office spaces and educational centers, while also being very energy efficient. One of the benefits of this calm and soothing light will be a visible increase in worker productivity as well as the creation of a pleasant atmosphere.
