Digital Fade Dimmers
Lutron dimmer types that provide a gradual fade-to-
off/fade-to-on feature when the switch is pressed, as
compared to the more traditional slide-to-off or rotary
dimmers that turn on/off with immediate response.
Digital fade dimmers also include LED indicator lights
to show the relative light level in the room.
Dimmer
An electronic control device used to vary the
intensity of light output from a lamp source.
Electronic dimmers reduce light level by reducing the
power delivered to the lamp source. This provides
energy savings. It also provides longer lamp life for
incandescent, halogen and low voltage sources
(e.g., 10% dimming doubles the expected lamp life).
Double-tap
A feature of some Lutron products in which two fast
presses (in quick succession) bring lights on to full
intensity, temporarily overriding any preset light level.
Driver
Auxiliary device needed to provide the correct power
to operate an LED light source. The driver regulates
the voltage and current to the LEDs. Dimmable
drivers also vary the intensity of light output by
reducing current or voltage.
Dual Device
A combination dimmer, switch, timer or fan control
that offers independent control of two groups of lights
or fans, and only takes up one gang electrical backbox.
eco-dim®*
A Lutron dimmer that guarantees at least 15% energy
savings compared to standard switches, and also
provides 3x longer lamp life.
eco-minder
TM*
A Lutron dimmer with LED lights that turn from red to
green to demonstrate when you are saving 15% or
more energy as compared to a standard switch.
eco-timer*
A Lutron timer switch that automatically turns a fan
or light off after a set period of time. It includes LED
indicators that change as the time counts down.
A one-minute blink warning signals when lights or
a fan are about to be turned off.
Electronic Low-Voltage (ELV)
A low-voltage incandescent or LED lighting source
that uses a solid-state electronic transformer or
driver to step down the incoming line voltage to the
voltage required by the lamp (typically 12 V). Most
ELV transformers are dimmable and use reverse
phase control (trailing edge) ELV dimmers. Track and
recessed down lights can be electronic low-voltage or
magnetic low-voltage. ELV transformers should only
be used with an ELV type dimmers.
Electronic Switch
Electronic switches use semiconductor device(s)
to turn on and off the current flow into the load.
They also include a mechanical disconnect or
air-gap switch to manually disconnect power for
safety when replacing lamps. These switches typically
need to be derated when ganged. Electronic switches
can only be used with the type of loads that they are
approved to operate and are listed under UL1472
or UL508.
Electrostatic Discharge Protection
Lutron products are designed to withstand static
discharges (static shocks) common in dry climates,
up to 16 kiloVolts, without damage or loss of memory.
Fade Time
The total time it takes the lighting controlled by a
dimmer to change from one preset level to another.
The time can be set from 0 seconds to 60 minutes.
Fan-motor Hum
The noise made by a fan motor at lower speeds when
controlling the fan using fully variable technology.
Lutron has quiet 3-speed and 7-speed controls that
do not cause the fan motor to hum.
Fin
The raised vertical metal dividers or side sections on
certain Lutron dimmers—these serve as “heat sink”
to dissipate heat.
