Once charged, you can use the wireless DMX feature to control the light. You can enjoy the unique lighting effects created by the 5 - watt QUAD LEDs in red, green, blue, and amber. When using it, avoid exposing it to extreme temperatures or moisture. For maintenance, keep it clean by gently wiping it with a soft, dry cloth. If you notice any issues, check the antenna to see if the elbow piece is still missing, and contact customer support if needed.
