The radiators are operated on 2s LiPo batteries and are cooled in flight by the air flowing around them. Therefore, they should only be switched on briefly on the ground.
The set contains 2 spotlights, each equipped with 4 super-bright LEDs on each end. They will require soldering the power connectors of your choice.
