- **Lumax Industries is India’s dominant automotive lighting maker - the company that puts the “eyes” on roughly two out of every three cars sold in the country - with a name that literally means “maximum light”. It began in 1945 as a small trading firm called Globe Auto Industries and transformed decisively in 1984 when it signed a technology partnership with Japan’s Stanley Electric, one of the auto lighting companies globally to manufacture LEDs; that four-decade alliance, plus a 1997 joint venture with Korea’s SL Corporation to serve Korean carmakers, turned a Delhi workshop into a 12-plant, 2,900-employee operation that now supplies almost 90% of India’s vehicle manufacturers. The recurring approach is simple: lock in the OEM relationship early, stay on every new model, and steadily move the technology up the value chain - from halogen bulbs to LED projectors to adaptive matrix beams - so that each generation of vehicle carries more Lumax content than the last.** # Business segments A single engine - automotive lighting - that spans every vehicle class on Indian roads, from Maruti hatchbacks to Mahindra SUVs to Hero two-wheelers, all fed by the same R&D backbone and the same 12-plant manufacturing network. ## 1. Automotive lighting systems: the group’s sole revenue engine **Lumax designs, makes and sells every lamp a vehicle needs - headlamps, tail lamps, fog lamps and interior lights - to nearly every major car and two-wheeler maker in India, with front lighting alone generating more than two-thirds of its business.** - **Headlamps are the cash cow** - front lighting contributed 69% of FY26 revenue, rear lighting 22%, and the rest came from fog lamps, interior lamps and auxiliary lights. Passenger vehicles account for 65% of sales and two-wheelers (plus three-wheelers) 29%, making the company the number-one lighting supplier for Indian cars and number three for two-wheelers. - **An 88% LED order book is remaking the mix** - the industry is shifting from halogen to LED because LEDs use less power, shine brighter and allow sleeker lamp designs, and Lumax’s LED share of revenue has already climbed from 58% in FY25 to 61% in FY26, with the order book now 88% LED, so the transition is largely locked in. - **One in two cars wears its lamps** - the company’s market share in passenger-vehicle lighting, together with its associate SL Lumax, reaches roughly 65-70%, and its top five customers (led by Maruti Suzuki, which alone holds about 42% of the domestic car market) bring in approximately 79% of revenues. - **Tooling is a second, higher-margin revenue stream** - when a new model launches, the OEM pays separately for the moulds and dies, and these tooling revenues generally carry better margins than the per-unit lamp sales, though the exact margin varies by programme. - **The moat is eight decades of OEM intimacy plus Stanley’s technology** - the company is present across multiple models of Maruti Suzuki, has confirmed orders for Maruti’s first EV, and recently won business on the Mahindra XUV 7XO, Skoda Kushaq facelift and Toyota Urban Cruiser Ebella, while the Stanley partnership gives it access to LED and electronics know-how that rivals cannot easily replicate. # In-house R&D, design and technology **Over 500 engineers across four design centres - two in India, one in Taiwan and one in the Czech Republic - turn Stanley’s core technology into application-ready lamps for Indian OEMs while building proprietary capabilities in adaptive beams, animated tail lamps and lit grilles.** - **Application engineering at scale** - roughly 500 engineers in India do the day-to-day work of tailoring lighting systems to each OEM’s specific model requirements, while a separate 22-engineer advanced-development team works on core technology and next-generation concepts. - **Proprietary software lowers cost and speeds up design** - the company built its own optical-design software suite to develop complex lens and reflector systems that optimise power consumption and appearance, and it uses a virtual-simulation tool called VRX from Optis to test headlamp light patterns on simulated roads before cutting physical prototypes. - **It made India’s first adaptive driving beam** - ADB technology lets drivers keep their high beams on without blinding oncoming traffic, and Lumax has already localised it; the R&D pipeline through 2032 includes matrix headlamps, micro-optics foils, road projections, night-vision integration and even ADAS sensor integration. - **Lit logos and grilles are the next frontier** - new regulations now permit illuminated brand badges and grille lighting, which is especially valuable for electric vehicles that lack a traditional grille, and Lumax is already developing these products. # Manufacturing footprint and operations **Twelve plants ring India’s automotive hubs - from Bawal and Dharuhera in the north to Bengaluru and Chennai in the south, and Chakan and Sanand in the west - with a dedicated electronics facility that has brought LED driver-board production in-house.** - **Electronics are now made, not bought** - the company set up a Surface Mount Technology (SMT) plant in 2019-20 to vertically integrate electronic components, and today the electronic content inside a Lumax lamp exceeds the plastic content; insourcing electronics added roughly one percentage point to EBITDA margin, and further scaling is expected to improve that. - **Localisation is reducing import dependence** - about 90% of conventional components are already sourced locally, and the company is working to localise LED components within the next year while diversifying its supply base toward Thailand and Indonesia to reduce reliance on China. - **A Bengaluru expansion is under construction** - a new plant to support Maruti Suzuki and Toyota’s upcoming models is being built at a capital outlay of around ₹140 Crore, with commissioning expected from Q4 FY27 and peak annualised turnover projected at roughly ₹450 Crore once ramped up. - **Total Productive Maintenance is the operating religion** - the manufacturing system runs on TPM structured around eight pillars, and multiple plants have won JIPM-TPM Excellence Awards, with the Bawal and Chakan III plants taking Gold at the 2025 International Convention on Quality Control Circles in Taipei. # Group structure and partners **Lumax Industries is the flagship of the Lumax-DK Jain Group, anchored by a 37.5% equity stake held by Japan’s Stanley Electric and complemented by a 21.28% stake in associate SL Lumax, which serves Korean OEMs from Chennai.** - **Stanley Electric is the technology anchor** - the partnership began with a technical-assistance agreement in 1984, became an equity relationship in 1994, and today Stanley’s 37.5% stake gives Lumax access to shared R&D, cutting-edge LED know-how and localised PCB production for Indian customers, with Stanley nominating directors to the board. - **SL Lumax captures the Korean OEM opportunity** - formed in 1997 as a joint venture with Korea’s SL Corporation, this Chennai-based associate (in which Lumax Industries holds 21.28%) supplies headlamps, tail lamps, fog lamps and chassis components primarily to Hyundai, Kia and Renault-Nissan, and recorded sales of ₹1,960 Crore in FY22. - **A Czech design centre extends the R&D footprint** - the wholly owned subsidiary Lumax Industries Czech s.r.o. operates the Lumax European Technical Centre in Ostrava, opened in 2022, which focuses on optics design, electronic hardware and software, and computer-aided engineering simulations for both Indian and international customers. - **Renewable-energy SPVs secure captive power** - the company has taken minority stakes in several special-purpose vehicles that generate solar and hybrid power for its plants, qualifying as a captive user under the Electricity Act, covering facilities at Dharuhera, Bawal, Sanand, Pantnagar, Chakan, Bengaluru and Haridwar.
