FLICKERING OR FLASHING WHEN OFF OR AT LOW DIMMING LEVELS
Modern LED lighting has revolutionised high brightness low power
lighting.
Unfortunately, some LED loads can have problems with dimmer
compatibility. This can be observed when lamps flicker or flash
when set to low dimming levels or when a MultiMate™ device is
set to the OFF condition.
The MMBP load bypass is wired across the lamp. It will resolve
almost all issues associated with dimming of LED lighting,
including:
-
Lamp glow when turned off;
-
Flickering or pulsing of the lamp when turned off or to low
dimming levels; and
-
Flickering or pulsing of the dimmer LED status indicators.
Solutions for lamp flickering at low dimming levels
Solution 1: Use the setup functions of the dimmer, timer, switch or occupancy sensor to adjust the
MINIMUM dimming level to a higher value. Refer to the product installation guide for details.
Solution 2: Fit a load bypass device – order code MMBP.
Solution 3: In extreme cases, both the MMBP and a raised minimum level may be needed.
Solutions for flickering or pulsing of dimmer LED status indicators.
Solution 1: Fit a load bypass device (MMBP).
Solution 2: Newer model dimmers introduce CLM mode. Use the setup guide for your product and activate
CLM mode.
Solution 3: In extreme cases, both the MMBP and enabling CLM mode may be needed.
Solutions for lamp flickering or flashing when turned OFF
Fit an MMBP load bypass. It is designed for this issue. Similar products are also available from other
manufacturers.
