Using this ETC Source Four 750 ellipsoidal light is easy. First, make sure to connect the stage pin properly to the power source. Then, use the C - clamp to secure the light in the desired position. Since it doesn't come with a lens tube, you'll need to use it as is or add your own if you have one. When using the light, avoid touching the bulb directly as it can get very hot. Also, keep it away from flammable materials. For maintenance, regularly check the connections of the stage pin and C - clamp to ensure they are tight. Clean the exterior of the light with a soft, dry cloth to keep it looking good.
