  • 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 Power Pack Reverse Phase preferred, but any mode will work.
    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 recommended Possible 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.

    Compatible dimming solutions:

    Dimming Product Recommended Module/Configuration
    EchoDIN 2x600W; Good Performance with all Settings between 22% and 100%. Min Scale: ca. 47V.
    Unison DRd EELV*

    Regulation: Off Transformer Mode: On

    Min Scale : 60V

    Sensor3 EELV*, ETR15AFR

    Regulation: Off and DC Prevent: On

    Min Scale : 27%, Control Mode : Smoothing

    Curve : Square Law

    Alex Mx Good Performance with default settings
    FDX3000/FDX2000

    DP90 dimmer

    Curve : Fluro2, Control Mode : Smoothing

    Other tested dimmers:

    Dimmer Software Version Dimmer Recommendations
    CE Smartpack V2.0.4 -

    Minimum 5 Fixtures

    Flicker between 0-20%
