Rosco Silk 210 Running on DC Sources

  • Designed to run on any voltage between 12V – 36VDC. However it is most efficient running at 24V. Below 20V the fixture becomes steadily less efficient.
  • For optimal performance run Silk on an AC transformer.
  • A second option is to run it on 24 V DC source, either with a block battery or with the Silk Double V – lock adaptor, BB-VLO-2X.
  • The third option is to run on one 12V battery using the V-lock or Anton/Bauer adaptor plate, BB-SIL-VLOCP or BB-SIL-ABCP. In this situation it is advised to use the highest capacity battery available. High capacity and heavy duty V-locks and Anton/Bauer batteries are available and High Draw versions are available from some manufacturers such as Hawk-Woods.
  • Manufacturers now offer a range of batteries that are designed for high current draw, up to 15A, ideal for use with Silk lighting products. A battery used on Silk 210 must have a current rating of >10A to cope with current draw at lower voltages to ensure it doesn’t cut out early and reduce running time.
  • There are a range of variables that effect battery life such as capacity, age, number of duty cycles, quality, and ambient temperature.
  • Silk firmware has been designed to protect the driver electronics. The entire display will flash a warning at 13V alerting the user that there is limited remaining capacity. At 12.5V the lamp will switch off and display “Lo OFF”.  The time between the warning display and cut out will vary but a typical duration would be 4 – 6 minutes.
  • Additionally there are other steps you can take to prolong battery life on Silk if running time is the priority. Roll off the output to <90% and walk the lamp in slightly closer to the subject if possible. This can increase the running time by up to 75%. Adjusting colour temperature below 5300K if possible will also increase running time. 4300K, for instance, if appropriate to your situation will increase running time by as much as 25%.
