The short answer: 40–60% gross margin is typical, 15–30% net margin after CAC and overhead. The variance is wide because permanent lighting margins depend heavily on three things installers control: customer acquisition cost, install efficiency, and material tier choice.
Gross margin breakdown
A typical $7,000 trim-only install for an installer running standard hardware:
| Line item | % of revenue | $ on a $7,000 install |
|---|---|---|
| Materials (LED track, channel, controller, transformer) | 25–35% | $1,750–$2,450 |
| Install labor (2-person crew, ~half day) | 15–25% | $1,050–$1,750 |
| Material delivery + freight | 2–5% | $140–$350 |
| Gross profit | 40–60% | $2,800–$4,200 |
That's before any acquisition or overhead expense. Net margin lands in the 15–30% range after the cost of acquiring the customer, the installer's overhead (truck, insurance, software, admin), and any callbacks.
What drives the upper end of gross margin
Efficient install crews
A 2-person crew completing a trim-only install in 4–6 hours instead of all day is the single biggest gross-margin lever. Cutting install labor from 8 hours to 5 hours on the same install moves gross margin up 5–8 percentage points.
Premium materials with longer warranties
Hardware like Starlights (lifetime warranty on the LED fixture) costs more per foot but commands a premium price tier the customer happily pays for. The premium tier improves gross margin AND reduces future service costs from failed channels.
Geographic clustering
Installing 3 houses on the same block in one day cuts drive time dramatically. The crew's effective hourly rate goes up, the truck spends less time in transit, and equipment setup is shared across multiple installs. Light Launch's neighbor follow-up workflow drives this exact pattern by automating same-block mailings after an install completes.
Pre-collected deposits
A 50% deposit at quote stage eliminates no-show risk, funds the material order, and filters tire-kickers before they consume install-crew time. Light Launch's customer portal collects deposits via Stripe Connect directly to the installer's account.
What kills the net margin
High customer acquisition cost
This is the silent killer. Installers running Facebook ads for cold acquisition typically pay $500–$1,200 per closed install. On a $7,000 install with $3,500 gross profit, a $1,000 CAC eats 28% of gross profit. Same install closed via a $200 mailed design quote (typical Light Launch installer math): CAC drops below $400 and net margin doubles.
The headline metric: average Light Launch installer returns $32 in install revenue for every $1 spent on mailed design quotes. That's the CAC math that protects net margin.
Callbacks and warranty service
Every callback costs labor + parts + an unhappy customer. Installers using off-brand hardware see significantly higher callback rates than those using premium tiers with longer warranties. The cost of one callback often equals the gross margin saved by buying cheaper materials.
Manual quoting and admin overhead
If quoting a single lead takes 30–60 minutes (drive + measure + calculate + send), the installer's time-per-quote eats margin even on closed deals. Light Launch's instant property measurement drops quote time to 30 seconds — the installer's time goes to selling and installing, not measuring and emailing.
Underpricing to "win the deal"
Dropping price by $1,000 to close a deal feels like a win — it's a 25%+ hit to gross profit on a $7,000 install. Compete on warranty and proof (rendered photo of the customer's actual house, lifetime warranty), not price.
How profitable is permanent lighting compared to other home services?
At the gross-margin level, permanent lighting compares favorably to most installable home services:
- HVAC install: typically 30–45% gross margin (higher material cost, longer labor).
- Solar install: typically 20–35% gross margin (heavy material cost, complex regulation).
- Roofing: typically 25–40% gross margin (material-intensive, labor-intensive).
- Landscape lighting: typically 35–50% gross margin (similar to permanent lighting but smaller average ticket).
- Permanent lighting: typically 40–60% gross margin (moderate material cost, short labor, high ticket).
Combined with low CAC achievable through mailed design quotes, permanent lighting net margins compare well to even higher-ticket trades.
The single number that matters most
Track install revenue per $1 of marketing spend. If you're below $10:$1, your acquisition channel is broken — fix that before anything else. If you're at $20+:$1, scale the channel. The average Light Launch installer is at $32:$1, which leaves room to invest in growth without eroding net margin.
