Four technologies of light
Lamp production, component fabrication, and precision measurement: quality completed within a single process.
Halogen Lamps
High-efficiency industrial lamps with tungsten filaments and high-purity quartz tubes that reach full heat in 1 to 3 seconds.
Carbon Lamps
Far-infrared lamps with carbon filaments that heat deeply and gently through penetration.
Component Fabrication
We precision-machine tungsten and carbon filaments. Quartz tube machining and custom shapes are handled on our own equipment.
Measurement & Analysis
Thermal imaging, color temperature, and power measurement verify quality to ±1.0% accuracy.
Three principles
behind 48 years
LIDO has built trust through its way of working, not its size. A corporate philosophy of producing, engaging, and advancing together is what defines the quality of our products.
Production
Six Sigma Quality Management
Data-driven decisions and statistical quality control deliver consistent products. We directly manage every step, from filament production to final inspection.
Engagement
Community Business
More than a supplier, we work to understand your process. Consulting and technical support tailored to your environment bring out the full performance of every lamp.
Advancement
Continuous Product Upgrades
We aim for lifespan and stability beyond required specifications, continuously improving materials and structure so our lamps run longer and heat more precisely.
A track record
proven in numbers
Our production record since 1976 is our promise of quality.
1976.
The first of its kind in Korea
While others relied on imports, LIDO developed its own industrial halogen lamps. That decision became a 48-year trajectory spanning semiconductor, automotive, and steel industries.
- 1976Developed Korea's first industrial halogen lamp; supplied headlamps to Hyundai Motor
- 2000sExclusive supplier of steel-sheet drying lamps to POSCO; introduced quartz machining equipment
- 2010sProduced semiconductor wafer cleaning lamps; began exports to Germany, Mexico and beyond
