Certain commercial grade stringers have a little loop built into the wiring above each socket. This loop allows a guy wire to be cleanly strung through the length of your stringer. Why? Because all the tension in the line can then be supported by the guy wire rather than your actual light stringer.
If you are using your stringers in an application where constant tension may shorten the life of your string or cause breakage you should consider using commercial stringers built with a guy wire loop. This is common for commercial applications where public
safety codes require this extra precaution. It is also recommended if you have a lot of wind or routine inclement weather.
Lastly, some people want to create a light pattern that needs the stringers to be straight with no swag. You can do this with the stringer itself, but it puts an incredible amount of tension on your end-points and can cause premature string damage. If you need perfectly straight lines for your patio lights, consider employing the guy wire method to improve the life and safety of your lights.
Patio string lights are commonly found in three colors: green, black and white.
- Green string light wire can be used for just about everything. It blends in well and can be used for both holiday and non-holiday applications. It is also ideal for blending in with tree canopy backgrounds.
- White string light wire is a little more unique and is common for special uses like wedding lights or decorative lighting during the holidays where you want your wire to blend in with the snow or house trim. Specialty parties or events use white wire as well because it is a softer color in the patio string light canopy.
- Black string light wire also blends in well given the setting so the use-case often comes down to color choice preference. It can be used in any setting for both residential or commercial applications. One color benefit is that if you plan to use multi-color light bulbs, the black wire is a more neutral color option than green and it will compliment your color lights better as a result.
