Permanent lighting installers price per linear foot. The only thing standing between an address and a quote is measuring the house. Done manually, that's a 30-minute drive to the property plus 10–15 minutes with a wheel, or a homeowner-reported number that's typically off by 20%+. Done with Light Launch, it's 30 seconds.
How instant property measurement works
When the Render Agent generates an AI render of a house, it simultaneously pulls a property measurement from a stack of Google data sources:
- Google Solar API provides detailed rooftop geometry — every facet, ridge, and edge of the roof with precise dimensions. This is the same data Google uses to estimate solar-panel sizing.
- Google Roads API identifies which side of the home faces the street (the front), so the system can distinguish front-of-house linear feet from whole-home linear feet.
- Satellite imagery fills in detached garages, accent gables, and ancillary structures the homeowner is likely to want lit.
The output is two numbers attached to every render: front-of-house linear feet (for trim-only quotes) and whole-home linear feet (for full-perimeter quotes). Both numbers feed directly into the customer portal's pricing tiers — the homeowner sees their trim-only and whole-home prices the moment they scan the postcard.
Why this changes the unit economics
Without instant measurement, the installer's workflow looks like this: render the house → drive to property → measure → return to office → manually calculate price → send quote → wait for response. Each step adds friction and drops conversion.
With instant measurement, the workflow collapses to: render the house → press send. The homeowner gets a postcard with their actual house rendered, scans the QR code, sees their custom price, and pays a deposit. Zero installer time spent on tire-kickers; the homeowner self-qualifies.
The math compounds. Light Launch installers average $32 in install revenue for every $1 spent on mailed design quotes, partly because the cost-to-quote a single lead is so low that mailing 200 houses at $1 each is rational. Without instant measurement, the cost-to-quote (driver time + labor) would make $1 mailings unworkable.
Accuracy and when to verify on-site
For typical single-family homes, the auto-measurement is within 5–10% of a hand-measured number — accurate enough to quote off and collect a deposit. The installer should still verify on-site before ordering materials, because materials are sized to the actual install, not the quote.
For homes with unusual features (multi-wing layouts, hidden courtyards, complex accent gables), Light Launch flags the measurement and lets the installer adjust before the customer portal goes live. A brief on-site confirmation before install day catches anything the satellite data missed.
How auto-pricing uses the measurement
In Light Launch, the installer sets two numbers in their account: their trim-only per-foot rate and their whole-home per-foot rate. From that point on, every rendered house auto-generates two prices:
- Trim-only price = front-of-house linear feet × trim-only rate
- Whole-home price = whole-home linear feet × whole-home rate
Both prices appear on the homeowner's customer portal, anchored to the rendered photo of their actual house. The homeowner picks the tier they're comfortable with and pays a Stripe deposit on the spot.

What this replaces
- Rolling-wheel measurements. A 10–15 minute on-site task that doesn't scale.
- Homeowner-reported numbers. Almost always off by 20%+ in either direction.
- Eyeballed Street View estimates. Fast but inconsistent across installers — and not a number you can quote against confidently.
- Manual Google Earth tracing. Accurate but slow, and the installer has to do it for every quote.
