relatively easy to mount the same slope
fixtures on a light bar or the cabin roof
and mirror mounts. Since fixtures are
highly efficient, they can be powered
using a standard inverter that takes 12-
volt, 24-volt or 48-volt to either 120V
AC up to 277V AC. There are no fila-ments
in Snow-Bright™ bulbs, so they
are not sensitive to vibration and units
come with a standard U-bracket, allow-ing
for easy and flexible mounting.
It is important to consider the visual
comfort of the operator, too. High glare
can cause eye fatigue, headaches and
reduced eye-hand coordination. Arti-ficial
light can impact sleep patterns
(circadian rhythms), mood and even
the immune system. Maximizing eye
comfort and visual efficiency reduces
adverse impacts upon machinery op-erators.
By using the snow surface as
a “light carrier” instead of a reflective
surface, less light provides greater de-tail
and depth perception.

the snow surface. Unlike conventional
metal halide and high-pressure so-dium
lighting, lighting levels are con-sistent,
eliminating hot spots and
voids. This is particularly important
when evaluating a surface for groom-ing
where contour and slope angle
are considerations.
LIGHTING
A high-pressure sodium fixture
emits a sharp “hot” beam of light with
a well-defined “V” pattern. Aside from
obvious voids, snow detail is not ob-servable
because the orange mono-chromatic
spectrum flattens the snow
appearance, obscuring contours, depth
and features. Even when sodium lamps
