Small Ultra-Power spotlight with up to 400 Lumen, CNC manufactured aluminium reflector with 16mm diameter and assembly plate for horizontal cooling. Ideal on undercarriages or as folding spotlights. The enclosed heatsink should necessarily be glued on for cooling purposes. It is recommended to directly glue the spotlight on the undercarriage leg with thermal conductive adhesive, then heatsink and mounting flange can be completely removed, so that only the reflector remains. Attention: this Ultra-Power luminaire has no temperature protection, a heat bridge connection to the carrier (undercarriage leg) is highly recommended.Direct operation with 2S LiPo (8V). With 3S (12V), the additional resistor has to be soldered in or use a 8W connection cable (accessories). Please ensure sufficient cooling air during operation.
