Using these stage can lights is quite simple. Just place them where you need stage lighting and connect them to a proper power source. Since they come with Apollo Gel filters, you can adjust the lighting effect as you like. When handling these used lights, be aware that they may have minor scratches and scuffs, but this won't affect their normal use. Also, as they are untested, it's a good idea to check them thoroughly before use. For maintenance, keep them in a dry and clean place. Wipe them gently with a soft cloth if they get dirty. Remember, this item can only be picked up locally at the MSU Surplus Store.
