NEO-RAY
DESCRIPTION
74IC/1T5 is the latest addition to Neo-Ray's family of high performance
indirect cove luminaires. Only 1-3/4" high by 6" long, this cove based on
dedicated T5 near field design packs 50% of the light into the critical 90 to
130 degree vertical angle zone and has an efficiency of over 81%. The new
74IC/1T5 produces a smooth gradation of light from the back of the wall to
the ceiling above and beyond the cove...without a hint lamp socket
shadows.
