In my experience (maybe this is a gross simplification of the issue) the most common way of changing brightness of an LED is through pulse width modulation, which can be a fairly straightforward circuit and firmware . I don't have any idea how complex this lighting fixture would be compared to a standard LED, whether it consisted of 1 LED or 100s but I would have thought something like this would have been specified in the contract with Grandlinq.
