Optimal for highway tunnel lighting! Domestic LED "Kiretsu" with zero defect track record.
Even in tunnels where exchanges are difficult, you can feel secure. The overwhelming quality of 1.8 million bulbs with zero defects and the pure domestic LED, perfected for heat resistance and weather resistance, protects a safe environment.
In locations such as highway tunnels where maintenance is difficult, the failure of lighting can lead to serious accidents, necessitating extremely high quality. KITERETSU is a highly reliable LED module that consolidates the technology cultivated in electronic device manufacturing, maintaining a "zero defect" record with the sale of 1.8 million units. It has evolved further to meet infrastructure standards. We are committed to pure domestic quality: both the LEDs and the constant current power supply circuits are all made in Japan. Improved heat and weather resistance: We have adopted polycarbonate for the lens and case, achieving durability that exceeds traditional epoxy filling. Brightness increased by 20%: By using the latest LEDs from Nichia Chemical, we have significantly improved heat dissipation and visibility. Equipped with protection circuits: It has built-in functions to prevent damage from reverse connections, helping to avoid construction troubles in harsh environments. With overwhelming reliability, we support the safety of public infrastructure over the long term.
