Recessed Indirect Troffers

combine the efficiency of a lensed troffer with the aesthetic quality of the indirect basket troffer.

High Efficiency Troffers

are fluorescent luminaires having indirect, semi-direct, and direct-indirect lighting distribution: they are designed to illuminate offices and other more finished spaces.

Linear Lighting Systems

Because the luminaires can be obtained in varying lengths and assembled into patters, they are called.
