Using the Dracast DRLED500DG LED500 Pro Series Daylight LED Panel Light is easy. First, if you're using the AC power, connect the included 100 - 240 VAC power adapter to a suitable power outlet. If you prefer battery power, attach a compatible battery to the Gold Mount battery plate. To adjust the brightness, simply turn the back - panel knob. You can dim the light from 100% to 0% with just a turn. When it comes to mounting, use the 5/8” receiver for the fixture mount or the TVMP/ Hex Bolt yoke mount as needed. For storage, use the included carry case to keep the light safe. Remember, this light has an IP20 rating, so it's not suitable for use in wet or dusty environments. Keep it in a dry place and clean it regularly with a soft, dry cloth to maintain its performance.
