NEO-RAY DESCRIPTION The optical design of the 74IC Cove Series is based on experience and knowledge of near field geometry and photometry. Actual performance of the 74IC Coves speaks louder than even what the photometric reports indicate...a smooth gradation of light is emitted to the back of the wall behind the cove to the far reaches of the ceiling above and in front of the cove...and this without the hint of lamp socket shadows.
