Dimming Performance

Minimum brightness from OFF Minimum Brightness dimming down to OFF 0.5% Approx 0.5% Approx

Smoothness of Dimming

RDT500: Very smooth dimming down to 1%. RDL500: Very smooth dimming down to 1% If anything: The visual performance is slightly better using Trailing Edge dimmer Slight flickering seen below 1% on occasion ? not a criticism

Audible Noise

Buzz from ballast with Leading Edge would be annoying. Silent with Trailing edge


"The Ballast/Lamp combination performed very well with RDT500 and RAK4T Dimmers. Trailing edge is much preferred due to audible buzz when using Leading edge dimmers."
