Holiday lights for Prince William County

PWC Lights is a free set of holiday decorating calculators for Prince William County homeowners — strands, outlets, cords, clips, décor counts, Halloween props, and season energy cost. Measure your porch, roofline, and yard once, then plan your own setup with a shopping list that fits.

Calculators run in your browser — nothing you type is uploaded. Community light and trick-or-treat maps are coming later this season. Learn more on About or reach us via Contact.

How the calculators help

Decorating calculators estimate quantities and loads before you buy more strands, panels, paint, or overload an outdoor receptacle — including specialty planners for luminaria candle packs, gift-box stack stability, blow-mold driveway lines, nutcracker porch fit, porch mitten clips, tombstone LED nights, dry-ice cauldrons, skull paths, silhouette stakes, reindeer antler wraps, candy-chute slopes, cobweb spray cans, and hanging-ghost clearance. Measure once, shop closer to the right count, then confirm against product labels. They are planning aids, not an electrical-code stamp. Full story: About · Contact · Privacy.
