The 290 GLS14 system utilizes a curved prismatic diffuser with multifaceted super fine linear prisms across the internal surface of the lens. The evenly illuminated, contoured reflecting system creates a soft, balanced illumination that enhances visual acuity. The white frosted diffuser has photometrically measured resins that obscure lamp shadows and maximize lighting performance. The 2 inch depth of the 290 GLS housing makes it ideally suited mechanically, photometrically and aesthetically for any ceiling. High fi xture effi ciency provides energy savings that will obtain LEED accreditation and meet all energy conservation codes, mandates and sustainability programs. This model has LPA Shielding.
