SPT-2 Wire is a great alternative to the standard SPT-1 Wire that most companies carry if you are looking to run higher wattage bulbs or do longer runs. As you can see from the picture on the left, both SPT-1 and 2 are 18 gauge wire (determined by the copper inside the wire), but SPT-2 (bottom of picture) has a noticeable amount more of insulation. This extra insulation allows this wire to be rated at 10 amps (as opposed to 7 amp Spt-1).SPT-2 is usually considered a commercial product, but works equally as well for small residential projects as well. We carry a full line of products for this wire type, bare wire, quick connect plugs, replacement sockets, and C7 & C9 Spools. Using 10 amp C7 spools will allow you use 7 watt bulbs without concern, and with C9 you can use 10 watts bulbs no problem.
Please note, you shouldn't mix and match Spt-1 and 2 products. For example, you shouldn't use SPT-1 barewire with SPT-2 sockets.
Unlike most big Christmas Light retailers we carry a wide varitey of C7 & C9 lightline spools in SPT-2. They are available in both Green and White wire colors, and in all major spacings.
