Overview

DTFU is at the forefront of clean area luminaire design featuring unique design solutions to ensure that IP performance is not compromised whatever the ceiling type. Combining robust construction with optical performance, DTFU incorporates the use of edge-lit optics with Nhex-prism diffusing technology to meet the most stringent glare control requirements of EN12464-1.
