Dimming Performance

Minimum brightness from off: 5% Minimum brightness from max: 3%

Smoothness of Dimming

With both the RMT and the RAK4-T when dimmed below around 10% and 5% respectively all fittings began to flash at different speeds rendering them unusable at below these dimming levels. This could be remedied by creating a custom profile in the software that very rapidly faded through the problematic area of the profile. Aside from this the smoothness of dimming was good in general with no flickering at all observed when used with the RMT and only very minor flickering from 5-10% of maximum outp

Audible Noise

No audible noise when used with any dimmer


The stated dimming performance values are for when all ten lamps are on and none are flashing.
