Shopify Home Lighting Schema — Lumens, Color Temperature, CRI, Bulb Base Type, ENERGY STAR & Smart Bulb Protocol Structured Data

Why Lumens Beat Watts for AI Query Matching

The single most damaging data gap in lighting product pages is listing watts but not lumens. Watts measure energy consumption — how much electricity the bulb draws. Lumens measure light output — how bright the bulb actually is. A 9-watt LED produces 800 lumens, the same brightness as a 60-watt incandescent. A shopper who searches "800 lumen bulb" or "equivalent to 60W" is expressing a brightness need, not an energy consumption preference.

AI shopping agents performing spec-filtered matching on brightness queries require a numeric lumens value with the correct unit code. When a product page publishes only wattage, the agent cannot resolve "how bright is this bulb?" from structured data alone and must either skip the product or attempt unreliable natural language extraction from the description. Including both lumens (UN/CEFACT unitCode LUM) and watts (unitCode W) in separate additionalProperty entries, plus a Replacement Equivalent Watts property, covers all three query patterns: lumen-based, watt-based, and incandescent-equivalent.

Lumens per Watt: LED Efficacy Context

LED efficacy has improved dramatically. A reference point for structured data descriptions: standard residential LEDs deliver 80–100 lumens per watt; premium LEDs reach 120–140 lm/W; commercial high-bay LEDs can exceed 160 lm/W. Incandescent bulbs produce approximately 13–15 lm/W. Include efficacy in the description field so AI agents can resolve "most efficient LED bulb" queries: "description": "800 lumens at 9W — 89 lm/W efficacy. Replaces 60W incandescent (13 lm/W)."

Smart Bulb Schema — Philips Hue A19 E26 Matter Example

The smart bulb example covers the complete spec set: lumens, CCT range, CRI, base type, dimmable, color capability, wireless protocol, smart ecosystem compatibility, ENERGY STAR, FCC Part 15, and lifespan. This is the reference schema for any WiFi, Zigbee, or Matter smart bulb product page.

Color Temperature (CCT) Reference Table

Color temperature in Kelvin (K) is the second most common lighting query attribute after base type. AI agents need the numeric CCT value (unitCode KEL) plus descriptive text covering the common-language equivalents ("warm white," "cool white," "daylight") so both numeric and descriptive queries match.

Bulb Base Type Compatibility Reference

Bulb base type is the most critical compatibility attribute in lighting — wrong base type = guaranteed return. Every lighting product page must encode base type as a structured additionalProperty with diameter and compatible fixture types in the description.

EnergyConsumptionDetails and ENERGY STAR Certification

ENERGY STAR certified LED bulbs must meet the EPA's minimum requirements: rated lumens at rated wattage (efficacy), rated life (minimum 15,000 hours for most categories), CRI (minimum 80), lumen maintenance (L70 — must maintain 70% of initial lumens at end of rated life), and starting time (<1 second). The FTC Lighting Facts label is required on all LED bulb packaging sold in the US.

For EU products, use the EnergyConsumptionDetails schema type with hasEnergyEfficiencyCategory linked to the EU A–G energy label. From 2021, all EU LED lamps reset to the A–G scale (previously A++ to E): most good LEDs currently land in C or D, with top-tier products reaching B or A. Include both the schema.org EnergyConsumptionDetails block and the raw efficacy in lumens-per-watt in your additionalProperty.
