Global Indoor Lighting Market Outlook, 2031

The global indoor lighting market is transitioning toward energy-efficient LED systems, supported by stricter efficiency requirements and updated product certification standards. In the United States, the Department of Energy's final rule requires general service lamps manufactured on or after 25 July 2028 to meet lamp-specific efficacy thresholds ranging from 92.3 to 195.4 lumens per watt. Integrated omnidirectional short lamps must achieve 124.6 lumens per watt, while non-integrated omnidirectional long lamps must reach 195.4 lumens per watt. Integrated LED lamps must also maintain a power factor of at least 0.7. The existing 45 lumens per watt backstop has been enforceable since 2022. According to NEMA lighting indices data submitted in the DOE proceeding, LED accounted for approximately 48% of installed lighting units in 2020, compared with 8% in 2015, indicating considerable scope for further replacement of conventional lighting technologies. Regional certification frameworks are also evolving. Commission Regulation (EU) 2019/2020 establishes minimum efficacy requirements for light sources and separate control gears used in indoor lighting products. China's CCC certification transitioned to GB/T 7000.1-2023 from January 2026, with old-version certificates requiring conversion by 31 December 2026 and subsequent revocation by 31 March 2027. India's revised IS 10322:2026 replaces earlier editions, with its transition period extended to 2 February 2027. Brazil's INMETRO Portaria 231/2026 introduces mandatory certification for LED luminaires, with separate transition deadlines for manufacturers, importers, and distributors. Other markets follow distinct conformity assessment approaches. Australia's GEMS LED Lamps Determination 2025 introduces minimum energy performance and labelling requirements from March 2026. Japan distinguishes between Class B luminaires eligible for circular PSE self-declaration and Class A LED drivers requiring diamond PSE third-party certification. Great Britain will require UKCA marking from 1 January 2028 following the end of the CE marking transition period.

The competitive landscape is shaped by DLC listing continuity, regional certification coverage, and fixture-level engineering capabilities. In North America, the DesignLights Consortium's SSL Technical Requirements Version 6.0, released on 3 November 2025, introduced an average efficacy increase of approximately 14% across product categories. The DLC also reports that efficacy requirements have increased by an average of 70% since 2011. Version 6.0 excludes downlights and E26 medium-base general-purpose lamps from its scope, leaving these categories subject to separate listing pathways. For covered products, high-bays must achieve 120 lumens per watt for Standard and 130 lumens per watt for Premium qualification, while linear ambient products require 125 and 145 lumens per watt, respectively. Troffers, linear ambient, high-bays, and low-bays can also qualify for efficacy allowances associated with enhanced glare control. The DLC Qualified Products List is commercially important because approximately 70% of North American energy-efficiency programmes use it to determine rebate eligibility. Manufacturers upgrading products previously listed under Version 5.1 must provide product-specific LM-79, LM-80, and ISTMT test reports to maintain qualification. International certification capabilities create another competitive distinction. China requires CCC certification, India follows BIS registration, and Brazil requires INMETRO conformity assessment. Japan's PSE framework places additional certification responsibility on LED drivers, while Great Britain's transition to UKCA introduces a separate market-access requirement. Installation-specific safety standards further differentiate manufacturers. IEC 60598-2-1:2025 governs fixed general-purpose luminaires, whereas IEC 60598-2-2 establishes particular requirements for recessed luminaires, including thermal protection and clearance from combustible materials. Manufacturers must therefore develop separate product configurations and testing documentation for different installation types.

Market Dynamics Driver: Efficiency regulations and incentive programmes accelerating indoor lighting replacement
• Increasing efficiency requirements are encouraging commercial, residential, industrial, and institutional users to replace older lighting installations with LED alternatives. The DOE's 2028 compliance deadline will accelerate the transition away from conventional lamps, while DLC Version 6.0 is raising the performance requirements for rebate-eligible commercial lighting products.
• Financial incentives and energy savings further support replacement demand. Approximately 70% of North American energy-efficiency programmes use the DLC Qualified Products List for product qualification, making listing status an important consideration in commercial retrofit decisions. The combination of electricity cost savings, utility rebates, and updated efficiency requirements encourages facility operators to modernise lighting infrastructure.

Challenge: Certification transitions and installation-specific safety requirements increasing compliance costs
• Indoor lighting manufacturers must navigate different regulatory transition schedules across major markets. China's CCC certificate conversion, India's revised IS 10322:2026, and Brazil's INMETRO Portaria 231/2026 introduce additional testing, documentation, and product approval requirements.
• The challenge extends beyond maintaining regional certifications. Different fixture installations require different safety assessments, particularly for recessed and fixed luminaires. IEC 60598-2-2 establishes specific thermal and clearance requirements for recessed products, while IEC 60598-2-1:2025 applies to fixed general-purpose luminaires. Consequently, manufacturers must manage separate testing processes and product specifications, increasing development costs and certification timelines.

Trend: Smart controls and application-specific optical engineering shaping fixture development
• Indoor lighting design is moving beyond uniform illumination toward systems that combine optical performance, automated controls, and application-specific functionality.
• ASHRAE 90.1-2025 reduces interior lighting power allowances by approximately 5–10% across building types under the Building Area Method. It also requires daylight-responsive controls to dim lighting to 10% power and reduces the automatic shutoff interval from 20 minutes to 15 minutes. These provisions encourage manufacturers to integrate occupancy sensors, daylight sensors, dimming systems, and compatible control gear into lighting fixtures.
• Optical engineering is also becoming more important. The DLC's enhanced-glare-control allowances indicate growing recognition of visual comfort alongside energy efficiency. These developments encourage manufacturers to differentiate products through beam distribution, glare management, lighting uniformity, and integrated controls rather than relying exclusively on lumen output.



Segmentation Analysis By Product Type
• Downlights are widely used in residential, commercial, and institutional interiors, particularly for recessed ceiling illumination. Their exclusion from DLC Version 6.0 means they follow a separate product qualification pathway rather than the SSL QPL thresholds applicable to other covered categories.
• Panel lights and troffers are commonly installed in offices, educational facilities, healthcare buildings, and commercial spaces. Their performance is influenced by energy efficiency, glare control, and compatibility with suspended ceiling systems.
• Linear lights serve offices, retail environments, industrial interiors, and other spaces requiring continuous or directional illumination. Their DLC qualification thresholds and compatibility with dimming and occupancy controls influence product specifications.
• Track lights provide adjustable illumination for retail stores, galleries, and hospitality interiors. Decorative fixtures address aesthetic lighting requirements in residential and commercial environments, while other indoor fixtures cover specialised applications.
• High-bay lights serve warehouses, manufacturing facilities, and other high-ceiling environments, where mounting height, optical distribution, and energy efficiency determine product selection.

By Lighting Technology
• LED represents the leading technology in indoor lighting fixtures because of its energy efficiency, longer operating life, and compatibility with automated lighting controls. Manufacturers are increasingly focusing on integrated LED platforms, driver efficiency, thermal management, and dimming capabilities.
• Fluorescent lighting remains in the installed base, particularly in older commercial buildings with troffers and linear fixtures. However, efficiency requirements and LED replacement programmes are accelerating its gradual displacement.
• HID lighting continues to serve selected industrial and high-ceiling applications, although LED alternatives are increasingly preferred for retrofit projects. Incandescent and halogen lighting retain limited applications in decorative and specialty fixtures, while other technologies serve niche requirements.

By Application
• Commercial applications represent a significant demand segment because offices, retail establishments, and hospitality facilities require extensive lighting infrastructure. ASHRAE 90.1-2025 efficiency and controls requirements influence product specifications and renovation decisions.
• Residential applications are driven by new housing construction, interior renovations, and replacement of conventional lighting fixtures with LED alternatives. Consumer preferences for energy efficiency, aesthetics, and smart lighting functionality also influence purchasing decisions.
• Industrial applications include warehouses, manufacturing facilities, and production environments that require high-bay, linear, and other specialised luminaires. Institutional applications cover schools, hospitals, universities, and government buildings, where lighting performance, operational reliability, and procurement requirements influence fixture selection.

By Installation Type
• Recessed installations include downlights and recessed troffers integrated into ceilings. These fixtures must satisfy applicable thermal protection and clearance requirements.
• Surface-mounted installations are used where recessed mounting is unsuitable or where existing ceiling structures make direct installation more practical. Suspended installations are common in offices, industrial facilities, and commercial interiors, particularly for linear and high-bay luminaires.
• Track-mounted installations provide flexibility through adjustable fixtures that can be repositioned along an electrical track. This configuration is particularly useful in retail stores, galleries, and exhibition spaces where lighting arrangements change frequently.

By Distribution Channel
• Direct sales are important for specification-driven commercial, institutional, and industrial projects. Manufacturers work with lighting consultants, contractors, facility operators, and project developers to determine fixture specifications, photometric requirements, and controls integration.
• Indirect sales through electrical wholesalers and lighting distributors support replacement, maintenance, and smaller retrofit projects. These intermediaries provide product availability, technical assistance, and access to certification information.
• Both channels contribute to the retrofit market, although larger projects generally require closer coordination between manufacturers, consultants, and contractors.

Regional Analysis • North America market is influenced by the DOE's existing 45 lumens per watt backstop and the 2028 general service lamp efficiency requirements. DLC SSL Version 6.0 establishes product-specific efficacy thresholds, including 120 and 130 lumens per watt for high-bay Standard and Premium products and 125 and 145 lumens per watt for linear ambient products. ASHRAE 90.1-2025 additionally reduces lighting power allowances, strengthens daylight dimming requirements, and shortens automatic shutoff intervals.
