Q1: Why should I choose the Aluminum Case NT series over the ET iron case series?
A: The Aluminum Case LED Driver with Junction Box offers two major advantages: superior heat dissipation and total rust resistance. For projects in coastal areas or applications where the driver is installed in tight, high-heat enclosures, the NT series ensures a longer lifespan and more consistent voltage stability.
A: Our 12V NT Series Triac Dimmable LED Driver is precision-calibrated for North American phase-cut dimmers. We recommend Lutron (Diva, Maestro, Caseta) and Leviton (Decora) for the smoothest 100-1% dimming performance.
A: In many North American jurisdictions, a UL Listed Class 2 Dimmable Power Supply is required for low-voltage lighting to pass fire safety codes. Class 2 units limit the available energy, allowing for safer installation in cabinetry and furniture without the need for specialized Class 1 wiring methods.
