These are ideal for low voltage electrical applications. This is REALLY BAD for anything that draws more than a 60 watt bulb. So you know what you are buying before you use them in your home. Use it on old vintage moving lights, tiny little bedroom lamps, modern low voltage LED replacement cords and that's about it. The price is so low that there is no harm in having them as a spare. But you'll want to buy high-performance patch cords elsewhere so you have the right cords for the right applications. MAKE SURE you know what you are doing. Otherwise, you may accidentally start a nasty house fire.
