Smart & Control Features

The VX20 features an integrated ON/OFF DC photocell for automated dusk-to-dawn operation without external control wiring (Aux Power Supply: No; Dim to Off: No).

Electrical

Powered by a Class 1 constant current driver operating on 120–277V AC at 50/60Hz (12.1–19.8W input watts). Delivers high electrical efficiency with a Power Factor of 98.7% at 120V (92.9% at 277V) for both Downlight and Up+Downlight modes, and Total Harmonic Distortion (THD) of 11.37% at 120V / 9.73% at 277V (Downlight) and 11.38% at 120V / 9.69% at 277V (Up+Downlight). Integrated 2kV surge protection protects internal electronics against transient voltage spikes.
