The AC3 junction box is an accessory for the Les Acrobates de Gras lamp series from DCW éditions. It allows several models from the same series to be connected to create a unique lamp constellation. Unlike the AC1 terminal box, which is connected directly to the power socket, the AC3 connects several lamps directly to each other, as if in a long chain. Up to 20 lightbulbs can be connected together, so a huge variety of combinations is possible.
