Performance Specifications
SOLID STATE DIMMING
Semiconductor device (triac or FET) turns the
lights on and off 120 times per second –
saving electricity and extending bulb life while
providing a steady, flicker-free illumination.
The benefits:
• save energy as you dim, reduce your utility
costs
• extend lamp life by running the lamps
cooler; reduce the number of lamps you
buy, install and discard
• dimmer handles full rated wattage capacity
Recommended submittal specification:
Controls shall be solid state, UL listed
specifically for each required load, and
capable of diming full rated wattage capacity.
VOLTAGE COMPENSATION
Special circuitry that maintains the power
delivered to the lamp in the event of line-
voltage variations.
The benefits:
• flicker free dimming through voltage
variations caused by elevators, chiller
pumps, building load changes or power
grid fluctuations
Recommended submittal specification:
Dimmer shall include voltage compensation
to stablilize light output from variations in the
AC line-voltage. DImmers in which the light
output is not held constant with varying AC
line-voltage shall not be acceptable.
LIGHTNING STRIKE SURGE PROTECTION
Special circuitry protects the electronics from
surges up to 6000 volts and 200 amps.
The benefits:
• protect your dimmer from power surges
during a storm or from power surges
generated within the building
Recommended submittal specification:
Controls shall meet ANSI/IEEE Std. C62.41-
1980, tested to withstand voltage surges of
up to 6000 V and current surges of up to
200A without damage.
AIR-GAP SWITCH
Visible and front accessible mechanism
activates a positive air-gap switch to
completely disconnect power from the load
for service.
The benefits:
• creates a safe condition for changing lamps
with no leakage current to the fixture
Recommended submittal specification:
All wall-mounted controls shall have a visible
and accessible mechanical air-gap switch to
totally disconnect power from the load so
that no leakage current shall be present at the
fixture(s), from all locations.
POWER-FAILURE MEMORY
Lights always return to the previous state
when power is restored.
The benefits:
• minimizes the inconvenience of power
service interruptions
• keep building lights as you left them when
you go away
• safety feature – will not default to "off"
Recommended submittal specification:
Controls shall incorporate power-failure
memory. Should power be interrupted (for up
to 10 years) and supsequently returned, the
lights will come back on to the same levels
set prior to the power interruption Restoration
to "off" or to some other default level is not
acceptable.
LOAD-SIDE OR LINE-SIDE
Wire the dimmer into either 3-Way switch
location.
The benefits:
• select dimmer location independent of the
wiring
• swap dimmer/switch location at any time
• simple to retrofit a switch with a dimmer
Recommended submittal specification:
Dimmer shall be capable of operating in
either 3-Way switch location.
ELECTROSTATIC DISCHARGE
PROTECTION
Designed to withstand the static discharges
(static shocks) common in a dry climate.
The benefits:
• protect the electronics within your dimmer
from static discharge
Recommended submittal specification:
Control shall not be susceptible to damage or
loss of memory due to 16kVolt static
discharges.
SQUARE LAW DIMMING
Dimmer output (lighting level) follows the
square law power curve.
The benefits:
• slider position matches the user’s perceived
light level
• no "dead spots" at top or bottom of the
slider travel
Recommended submittal specification:
Dimmer slider position shall indicate
perceived light level, using the square law
power curve in the IESNA Lighting
Handbook.
PRECISE COLOR CONSISTENCY
Color variations are monitored to ensure that
all visible plastic parts have a consistent
color.
The benefits:
• all CORE dimmers, switches, receptacles,
and wallplates match across the family
• new dimmers can be added to an existing
location with precise color matching
Recommended submittal specification:
To ensure a precise color match between all
plastic parts, color variation of any control
shall not exceed a
r
E of 1.0, as defined in
ASTM E 308-99.
UV STABLE COLOR
Visible plastic parts do not fade or yellow
with prolonged exposure to sunlight.
The benefits:
• durable plastic maintains quality color
throughout the product life
• new dimmers can be added to an existing
location with precise color matching
Recommended submittal specification:
To ensure colors do not fade or yellow, visible
parts of controls or wallplates shall exhibit
ultraviolet stability as defined in ASTM
D4674-89.
SMOOTH AND CONTINUOUS DIMMING
Smooth and continuous lighting control
across the dimming range.
The benefits:
• flicker-free continuous lighting control
Recommended submittal specification:
Dimmers shall provide smooth and
continuously variable control of light intensity.
