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 Cove 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.
