Using this ETC Source Four Jr ellipsoidal light is easy. First, make sure you have a proper power outlet for the Edison plug. Just plug it in, and the light with its 36 - degree beam and 575 - watt power will start working. Remember, this product doesn't come with a C - clamp, so if you need to secure it, you'll have to get one separately. For maintenance, keep the bulb clean. You can use a soft, dry cloth to wipe it gently. If the light doesn't work, check the power connection first. Replace the bulb if it burns out. Always handle the light with care to avoid any damage.
