Homeowners replacing bulbs who can't tell lumens from watts

Features
  • Room-photo analyzer that maps fixture type, ceiling height, and daylight to recommended wattage-equivalents
  • Side-by-side SKU compare that calculates euros/dollars spent over 5 years (electricity + replacements), not just sticker price
  • Photographer/relax mode: tells you when a $3 1keur 1000h bulb beats a $8 25,000h LED for that reading lamp or photo corner
  • Buy-it-once checklist: warns when a 'long-life' bulb is dimmer, yellower, or worse CRI than your old one
Why now

After a decade of LED transition, packaging still shows watts, leaving shoppers confused about the real lumen/color/lifespan trade-off this HN article explains — buyers are actively searching for clarity.

Lumens-vs-watts confusion is real and persistent (FTC publishes consumer guidance on it), but bulb replacement is a low-frequency event and shoppers typically just grab whatever matches the socket at the hardware store — strong need, weak urgency.Shopping for Light Bulbs | Consumer AdviceLumens vs Watts: What Really Tells You a Bulb Is Brighter?

The 'snap a photo to identify a bulb/socket and get replacement SKUs' flow is already live at multiple players — findalamp.com, ledlightinginfo.com, whatsthatlamp.com, plus the MWM 'Light Bulb & Lamp Identifier' iOS app — leaving little room for a near-clone.Free Light Bulb Identifier - Snap a Photo to Find Your LED Replacement | Find a LampAI Light Bulb Finder — Identify Any Bulb From a PhotoLight Bulb & Lamp Identifier - App Store

Monetization
3/10

Bulbs are a $2–$8 commodity; Home Depot affiliate pays ~1% and Amazon Associates rates for lighting are similarly thin. Replacement frequency is low (years per socket), making subscription models unrealistic and affiliate LTV per user small.The Home Depot Affiliate ProgramAmazon.com Associates Central

Longevity
5/10

LED transition is already ~70%+ complete in US households; as it finishes and lumen-only labeling becomes standard, the underlying confusion problem naturally decays over 5–10 years, and future 'smart' bulbs may embed SKU/QR data on-pack, eroding the use case.Shopping for Light Bulbs: What to Look for | Consumer Advice

Feasibility
8/10

Technically straightforward: socket/base CV is a known problem, public SKU catalogs (Amazon, Home Depot APIs) exist, electricity tariff lookup is regional and simple — a small team could ship a working MVP in weeks.
