Back box and spacers
This Lightwave smart dimmer requires a 35mm deep
back box in which to mount it. If you have a back box
that is shallower than 35mm, then a Lightwave spacer
can be used to provide up to 10mm of extra clearance
from the wall.

LED Lamp compability
Lightwave dimmers are designed to work with the
majority of dimmable LEDs, but, as every lamp can
behave dierently, it is advisable to choose variants
that have been tested and proven to work well. If you
plan to use LEDs, we strongly recommend that you
consult our compability chart (see www.lightwaverf.
com). The LEDs must be dimmable (not all variees
are), and you should not exceed the maximum loading
recommendaons provided on the compability chart
or damage could occur.
Compable lamps
• Mains voltage incandescent lamps (max 280W)
• GU10 / HI spot halogen lamps (max 280W)
• Selected dimmable LEDs (see www.lightwaverf.com)
Not compable with:
• Wirewound transformers (generally older style)
• Electric motors
• CFLs and CFL tubes
• Incandescent lamps under 10W
