Using the SGC 2 - Foot LED Tube Light Control Grid is a breeze. First, pick the right size, either 2 - foot or 4 - foot, according to your tube light. Then, simply place the grid over the tube light. It fits SGC Lights and other similar brands. When not in use, keep it in the provided travel drawstring pouch to protect it. For maintenance, use a soft, dry cloth to gently wipe off any dust. Avoid using harsh chemicals or getting it wet, as this may damage the grid.
