NEO-RAY
DESCRIPTION
The new 4" wide flush narrow basket recessd Fenestra offers interior spaces
both comfortable lighting and economy. T5 fluorescent configurations
produce efficiencies of close to 80% which means typical rooms may be
illuminated with approximately 10% less fixtures when compared to
recessed parabolics. This installation cost differential makes the Fenestra
flush narrow basket comparable to the cost of 2'x4' recessed parabolic
system.
