CONTROLLED ENVIRONMENTAL
LIGHTING SYSTEM
A system which controls light intensity in churches,
auditoriums, restaurants and other buildings is now
available from Stage-Brite, Inc., Minneapolis, Minnesota.
The C.E. L. (Controlled Environmental Lighting) System
employs solid-state SCR dimmers to deliver a selected
light intensity in specific areas or rooms. The dimmers, in
3.6 KW capacities are enclosed in modular, slimline wall
mou nted racks.
The C.E.L. System comes with one of three modes of
dimmer control which give smooth fades from "full
bright" to "off". The UDP control module is complet~ly
solid-state.
It features pushbutton activation and
adjustable fade speed from 5 to 30 seconds. LVL-SET
module has solid-state circuitry and factory-set fade
speed. RC-1 module has one calibrated rotary knob for
manual control of light intensity and fade speed.

unit (SCU), a m~dular, microprogrammable controller
designed and manufactured for Berkey Colortran by

nanoseconds. The SCU can respond to over 2.8 million
commands per second, and continuously self-checks to
ensure operational integrity or working programs.
Available peripheral devices include a digital tape
cassette recorder, "f loppy disc" recorder, teletype
terminal, color television monitor and special scene status
