Abstract: A remote-controllable lighting device comprising a first substrate and an adjacent second substrate maintained in a spaced apart relationship to allow airflow therebetween and at least partly overlapping each other, at least the second substrates carrying thereon at least one emission sources, the first substrate being located towards a proximal end of the device and the second substrate being located towards a distal end of the device; said first substrate being arranged so as to allow light generated by the at least one located second light emission source to pass thereby in a direction defining a primary light emission direction and said first light emission source located so as to emit light in said primary light emission direction; said first and second substrate being in thermal communication so as to allow heat generated by the at least one light emission sources to flow between the substrates so as to provide thermal distribution between the substrates, the first and second substrate being formed of a
