Measure your roofline once, tell us the bulb style and color you want, and this figures out how
many of which set actually covers it — no guessing by bulb count alone, which is the single most
common way people buy the wrong number of light sets.
Mini LED (subtle, modern)
C9 (large, bold, traditional)
C5 (smaller than C9, still a rounded bulb)
Warm white
Multicolor
Either / don’t mind
How this works
Each catalog set covers a fixed length (printed on its own listing). The calculator divides
your roofline length by that set’s length and rounds up — so you always get enough to cover the
full run, with a little overlap rather than coming up short partway across the roofline. If your
roofline needs more than one style to look right (e.g. a longer run plus a shorter porch section),
run the calculator twice.
Always confirm the exact connect/daisy-chain limit on the product’s own listing before buying
multiple sets to run end to end — that limit varies by set and by total wattage, and isn’t
something this calculator can check for you.
