Portfolio has been added to the Halo
Lighting family of specification grade
downlighting. Matching apertures at 4, 6, and 7-3/8
inch diameters allow one to match a variety of
distributions, with a consistent visual appearance. All
units have equal cutoff to lamp and lamp image, assuring
glare free illumination in all optical
distributions. As well, all of the Portfolio wall
wash downlights are built with Halo's patented Geometric
Reflector for Uniform Vertical Illumination. Commonly called
GRUVI, the system incorporates a series of calibrated facets
within the reflector, providing the kind of precise wall
wash that has been recognized by lighting designers,
lighting engineers, and end users alike for its superior
wall washing with smooth patterns of light and no
flashback. Also, the incandescent and low voltage
adjustable fixtures in the Portfolio series include a unique
tilt mechanism that keeps the center of the beam aligned
with the center of the aperture at all tilt angles,
maximizing light output over all aiming angles. Halo / Brand of Cooper
