Wiring

Limelight takes a 12V input, but is built to function down to 4.5V. Its LEDs have a constant brightness down to 7V.

caution

Do not use the REV radio power module to power your Limelight. Its output voltage is too high.

  • 2024 Update - We recommend the use of a separate VRM to power up to 2 limelights via the 12V outputs. The VRM will help protect your Limelights against load dumps and high voltages due to new regenerative braking features.
  • Do not run wires to your VRM.
  • Run two wires from your limelight to a slot on your PDP (NOT your VRM).
  • Add any breaker (5A, 10A, 20A, etc.) to the same slot on your PDP.
  • Run an ethernet cable from your Limelight to your robot radio.

Wiring Best Practices​

  • Add strain reliefs to all power and ethernet cables going to your LL.
  • Hot-glue all connections.
  • Add a network switch to your robot to enable ethernet tethering while at an event and to avoid the second radio port. We recommend the Branboxes SW-005 5 port Switch
  • Use twisted Cat6 cables with stranded wires
  • We do not recommend use of the second radio port. Route all devices through your network switch if possible.
