If you've spent more than $1,000 on Facebook ads for your lighting business and the math hasn't worked, you're not alone. The channel underperforms for permanent lighting in a way that no amount of optimization can fully fix. Here's the structural breakdown.
Facebook ads assume three things — permanent lighting breaks all three
1. Assumption: visual products can be sold with stock imagery
Facebook's ad creative library is built on stock images and short video clips. For most products, this works — a clothing brand can show a model in their shirt; a meal kit can show a finished dish. The viewer projects themselves into the image.
Permanent lighting breaks this because the homeowner needs to see their house, not someone else's. A generic before/after photo of "a house with permanent lighting" doesn't trigger purchase intent because it's not their house. Facebook has no way to show personalized creative at the per-home level.
2. Assumption: high-ticket products can be sold to broad audiences with enough touches
Facebook's optimization works on volume — show the ad to enough people, retarget the ones who engaged, and convert through repeated touches. This works for $50–$200 products with short consideration cycles.
A $5,000–$15,000 permanent lighting install needs real intent at the top of the funnel. Cold Facebook traffic burns money on tire-kickers who clicked but were never seriously considering a five-figure home improvement project. The cost-per-actually-qualified-lead inflates because the funnel is too leaky.
3. Assumption: targeting can identify in-market buyers from demographic signals
Facebook's targeting is great at "homeowners in this zip code interested in home improvement." It's terrible at "homeowner who will be in-market for a $10K exterior lighting install in the next 90 days." That second filter is the one that actually matters, and there's no signal in Facebook's data that reliably identifies it.
The math, concretely
- Cold Facebook campaign for permanent lighting: typical CPC $2–$5, CTR 0.8–2%, lead-form fill rate 5–10%, lead-to-close rate 3–8%. Effective CAC: $500–$1,200.
- Light Launch mailed design quotes: $1 per home in-hand impression, 15–20% scan rate, 50% of scans pay a deposit, 50% of deposit-paid book an estimate, 50% of estimates close. Effective CAC: $200–$400.
The 3–6× CAC difference is structural, not tactical. Better creative, better targeting, better landing pages don't close it.
When Facebook DOES work for lighting installers
Two narrow cases:
- Retargeting. A small budget aimed at people who already visited your website or watched a video. They've already self-identified as warm; retargeting closes them efficiently.
- Brand awareness in a service area. Low-budget awareness campaign in zip codes where you're about to mail. Helps the mail campaign convert better because the brand is already familiar.
Neither of these is a primary acquisition channel. Both are amplifiers for the channels that actually do the heavy lifting (mailed design quotes, referrals, neighbor follow-ups).
What to do instead
