The problem with the complete C9 and C7 light sets sold in stores is they typically only use 20 gauge wire, which means they can’t handle much current and cap out at around 60-75 incandescent bulbs. With the stringers you buy separately, they typically use 18 gauge wire, so they can handle a lot more lights and you can have long stretches of lights without extension cords everywhere.
Can you comment on the number of articles I have seen saying to limit the length of SPT1 wire to 250 ft or 250 bulbs, regardless of bulb type? I am looking to light 1000' of fence line and would like to use opticore c9 bulbs, but unsure if I can truely use 1000' of 18 gauge wire from a single plug.
Hi! If you're unsure about a specific installation situation, it's best to consult an electrician. They can give you answers based on your exact conditions.
