Lighting is still tied to about 40% of building electricity use, yet the same agencies that map the problem also point to big reduction potential through efficient technologies. At the same time, the LED market climbed from $72.2 billion in 2022 to a projected $143.8 billion by 2030, while smart connected lighting has moved from early pilots to wider adoption, with 76% of respondents planning to use it. This post stitches together the technical, market, and safety standards behind that shift, from color quality metrics like TM-30 to controls and lifetime testing that affect what ends up in real spaces.
Key Takeaways
- 40% of global electricity use in buildings is attributed to lighting in older IEA framing; the IEA estimates that lighting can be reduced substantially with efficient technologies (share of building electricity for lighting)
- 76% of respondents in a CEBA survey on connected lighting reported they use or plan to use connected lighting (share of respondents by intended use)
- A 2021 meta-analysis reported that daylight-linked controls can reduce lighting energy use by about 25% on average (percent reduction from daylight harvesting/control interventions)
- In the European Union, lighting accounts for about 5% of total electricity consumption (used as a proxy for the scale of lighting demand within power usage)
- The global LED lighting market size was $72.2 billion in 2022 and is projected to reach $143.8 billion by 2030 (market revenue for LED lighting products)
- The global architectural lighting market is forecast to grow from $xx.xx billion to $yy.yy billion by 2030 at a CAGR cited in a vendor research report (market revenue for architectural lighting)
- IES TM-30 provides a detailed description of color quality via Rf and Rg metrics (measurable color fidelity outputs)
- Correlated Color Temperature (CCT) of white lighting products typically falls in the 2700K to 6500K range for commercial specifications (measurable CCT range used in specs)
- Color Rendering Index (CRI) is measured on a scale of 0–100, with higher values indicating better color rendering (measurable definition used by lighting professionals)
- A 2019 peer-reviewed life-cycle assessment found that LED lighting has a lower total global warming potential than fluorescent lighting for typical lifetime scenarios (relative LCA result measured as comparative GWP)
- A NREL evaluation of LED streetlight conversions found typical savings of about 50% on energy use (retrofit savings metric for public/professional lighting)
- DALI is supported by thousands of luminaires and drivers; DALI Alliance reported more than 100 companies in the ecosystem (adoption measured as supplier ecosystem count)
- Signify reported that its LiFi-enabled luminaires achieved commercial deployments in public spaces and retail locations (measurable deployments count reported in press releases)
Efficient LED and connected lighting could cut major electricity use, with standards like TM-21 and TM-30 ensuring performance.
