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.

*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.
