 What makes dimming a dimmable LED/CFL bulb different than dimming an incandescent
bulb?
Dimmable LED and CFL bulbs contain electronic circuitry not present in incandescent bulbs.
Therefore, it is difficult to achieve the same smooth start and complete dimming range as one
sees with incandescent bulbs. The Decora Digital Dimmer is designed to interact with the
electronic circuitry, providing smooth low level dimming on the majority of bulbs by major
manufacturers.
 Are there any adjustments that will need to be made to the Decora Digital Device based on
the bulb I choose?
Decora Digital Devices are preset to the following bulb types:
DDMX1: Incandescent/MLV mode
DDL06: Incandescent mode
DDE06: Electromagnetic Low Voltage (ELV) mode
DD710: There are no bulb options; this dimmer can only control 0-10V fixtures
DDF01: There are no bulb options; this device can only control a ceiling fan
DDS15: There are no bulb options
If your Decora Digital Dimmer is controlling a different bulb type, you should set the device to
the proper type of bulb you are controlling via the Decora Digital Dimmer & Timer App:
Advanced Setting / Bulb Options.
Dimmable CFL bulbs may also require an additional “kick start*” or automatic adjustment to
turn on. In this case, the dimmer will need to be set to CFL mode. Please refer to the instruction
sheet for details.
 Can I use dimmable LED bulbs when the dimmer is set to CFL mode?
This is perfectly acceptable, especially if you encounter LED bulbs that are difficult to start at a
low preset dimmer level. In CFL mode the dimmer will provide increased energy or a
“kick start*” to start the bulb.
 My dimmable LED/CFL bulbs do not turn on when at the lowest dimmer setting. What can I
do?
The dimmer features a “kick start*” feature that provides an additional energy boost for hard to
start bulbs. Simply set the load type to the bulb you are currently using via the app to activate
this mode. Also, some bulbs have wider dimming ranges than others. In order to take
advantage of the full dimming range of the bulb, use the app to adjust and set the minimum
light level.
* “Kick start” is a precise boost of energy applied to difficult to start CFLs to initiate smooth start up and prevent
flickering. This feature maximizes the usable dimming range by allowing the user to start at the lowest possible
dim/bright bar position.
