Source Four Mini LED Dimming Performance

We have tested the Source 4 Mini LED on a number of platforms. This is a line dimmed LED fixture. Depending on the type of dimmer, different minimum quantities of fixtures may be necessary on a circuit for smooth dimming performance.

120V Dimming Information

Fixture performance:

Minimum turn-on voltage 34V+
Recommended Minimum Scale voltage 34V (or 27% of control)
Dimming performance Smooth and continuous from 120V-34V
Fade anomalies One minor shimmer detected around 95% of control during fade up*
Steady state performance Steady at level
Phase dimming compatibility Forward or reverse**

+ Can vary based on fixtures and wire length

*Shimmer Resolution: adjust max scale voltage to avoid unstable levels.

**Reverse phase recommended for transistor dimmers.

Note: Use Smoothing when available

Compatible dimming solutions:

Dimming Product Recommended Module/Configuration
Echo 120v Phase Adaptive Dimmer Auto Mode preferred 
Foundry 120v Phase Adaptive Dimmer Auto Mode preferred 
Unison DRd D20, ELV*,L10
  Regulation: Off Transformer Mode: On
Sensor3 D20, ELV*, TR20AF
  Regulation: Off and DC Prevent: On

*ELV in forward phase mode requires 30V minimum voltage in Paradigm and 27% of control from Sensor 3.

Note: D20AF performs smooth and continuous dimming throughout the recommended range, but suffers from a shimmer at steady state control levels around 95%. For this reason, it is not on the list of compatible dimmers.

Other tested dimmers:

Dimmer Software Version Dimmer Recommendations
Sensor Classic v3.1.1 D20 Minimum 5 Fixtures
      Minimum voltage 45V
Unison DR N/A D20 Minimum 5 Fixtures
      Minimum voltage 45V*
    L10 Not recommended
SmartPack v2.0.4 N/A Not recommendedPossible misfires with any number of fixtures in line
SmartBar 1 v1.67 N/A Not recommended due to misfire flashes to full
SmartBar 2 v2.0.0 N/A Minimum 6 fixtures
      Minimum voltage 35V
ES750 ---- ---- DO NOT USE. ES750 SUITABLE FOR INCANDESCENT LOADS ONLY

*Lights could flash below this point. Flashpoint can vary based on number of fixtures and wire length.

230V Dimming Information

Fixture performance:

Minimum turn-on voltage 60V+
Recommended Minimum Scale voltage 60V (or 27% of control)
Dimming performance Smooth and continuous from 230V-60V
Steady state performance Steady at level
Phase dimming compatibility Forward or reverse**

+ Can vary based on fixtures and wire length

*Shimmer Resolution: adjust max scale voltage to avoid unstable levels.

**Reverse phase recommended for transistor dimmers.
