Large high-altitude billboards are also safe! The LED "Kiretsu" aims for maintenance-free operation.

Significantly reduce the cost and risk of high-altitude work! With a proven track record of zero defective bulbs out of 1.8 million and the durability of purely domestic products, we prevent bulb failure issues in large signboards before they occur.

The large sign located at a high place requires scaffolding or aerial work vehicles when LED failures occur, resulting in enormous replacement costs and effort. KITERETSU has maintained "zero defects" with the sale of 1.8 million units through strict quality control cultivated in electronic device manufacturing. We minimize the running costs and risks of high-altitude signs. We have enhanced each function for stable long-term operation. Overwhelming trust in pure domestic production: We are committed to having all LED modules and power supplies made in Japan. Use of polycarbonate: Adopted for lenses and cases, significantly improving heat and weather resistance compared to traditional epoxy filling. Brightness increased by 20%: With the latest LEDs from Nichia Chemical, we ensure high visibility that stands out from a distance. Reverse connection protection circuit: Prevents module damage during installation and supports secure installation. For "signs that are difficult to replace," choose the highly reliable "KITERETSU."
