Verified Comparison
Grow Light Dimming Protocols Compared: AC Infinity vs VIVOSUN vs Spider Farmer vs Mars Hydro
Comparison of LED grow light dimming protocols across AC Infinity (UIS/0-10V), VIVOSUN (GrowHub/RJ11), Spider Farmer (RJ12 Daisy-chain), and Mars Hydro (RJ12 iHub).
Multi-Brand Technical Matrix
| Brand | Primary Protocol | Connector Type | Cross-Brand Adaptation |
|---|---|---|---|
| AC Infinity | UIS (PWM / 0-10V) | UIS Proprietary & Type A (RJ11/RJ12) | Adapters available for Mean Well & RJ11 fixtures |
| VIVOSUN | GrowHub (RJ11 / PWM) | RJ11 6P4C Port | Direct daisy-chain with AeroLight & compatible drivers |
| Spider Farmer | 0-10V Linear Dimming | RJ12 6P6C Daisy Chain | Multi-light linking; requires converter for UIS |
| Mars Hydro | Smart FC Dimming | RJ12 Daisy Chain | Compatible with iHub; requires passive/active bridge for others |
