DESCRIPTION

DIMENSIONS

The Paralux V series features a
proprietary “Total Light Control
System” that has been designed
to eliminate glare reflections in
VDT screens by suppressing high
angle brightness. Meets today’s
lighting standards. The luminaire
incorporates a precision cut-off
parabolic louver in a para­contoured fixture housing. This
system complies with RP-1 and
meets today’s lighting and
energy manage-ment standards.
The series is compatible with all
of today’s popular ceiling
systems. The Paralux V, PC|2
series is the solution for
computer environ-ments and
open office areas.

RP-1 1ST LEVEL

The concept of RP-1 is simple; by suppressing high angle brightness,
reflected glare will be avoided in the VDT screen at the normal tilt
angle. The 1st level sets the toughest standard.

The 1st level or preferred level states that the average luminance
brightness in the lengthwise (0°), crosswise (90°) and 45° lateral
planes should not exceed the following:

Candelas/M

850 Candela/sm at 55° from vertical 250 fl at 55° from vertical
350 Candela/sm at 65° from vertical 100 fl at 65° from vertical
175 Candela/sm at 75° from vertical 50 fl at 75° from vertical
175 Candela/sm at 85° from vertical 50 fl at 85° from vertical

RP-1 2ND LEVEL

The 2nd level is relaxed. It is suitable for areas where intermittent
computer work stations exist.

The 2nd level states that in no case shall the luminance brightness
exceed the following in the lengthwise (0°), crosswise (90°) and 45°
lateral planes:

Candelas/M

850 Candela/sm at 65° from vertical 250 fl at 65° from vertical
350 Candela/sm at 75° from vertical 100 fl at 75° from vertical
175 Candela/sm at 85° from vertical 50 fl at 85° from vertical

This view of the ceiling and room space illustrates the vertical plane
with vertical angles (light/dark grey area) from 0° to 90° in the 0°
(lengthwise) lateral plane. Notice the light grey areas. This is where
the Metalux Precision Parabolic bends the light into a confined cut­off-zone, 0° to 55°, (1st level). Now notice the dark grey areas. This is
where the light is restricted in the shielded zone, thus eliminating
high angle brightness (glare) in the VDT screen.
