• a base plate;
• and
• a pedestal structure protruding from the base plate toward the case cover;
• and
• a first layer vertically offset from the heatsink base by a base post of the heatsink base, the first layer comprising a first printed circuit board and having a first layer opening,
• wherein the pedestal structure passes through the first layer opening, and
• wherein one or more components of at least one of the power supply or the light driver are mounted on at least a top side of the first layer facing away from the base plate.
