basic information
○ Long Lifespan The lifespan ensures 90,000 hours for both basic and entrance lighting. Basic lighting is maintenance-free for over 10 years with 24 hours of operation per day (24 hours × 365 days × 10 years = 87,600 hours ≤ 90,000 hours). Entrance lighting is maintenance-free for over 20 years with 12 hours of operation per day (12 hours × 365 days × 20 years = 87,600 hours ≤ 90,000 hours). ○ Lightweight and Compact, Improved Installability ● The main body uses aluminum alloy, achieving industry-leading lightweight and compact design. It excels in installability and safety. ● Due to its compact size, it can be installed in narrow cross-section tunnels where installation was previously difficult. ● The number of anchor bolts required can be reduced from four to two (the fixture can be mounted using two points on either side of the central mounting hole). Safety Measures ● The front cover is secured with a hinge-less latch structure, reducing corrosive materials and minimizing the risk of the front cover falling due to aging deterioration. ● A fall prevention structure is adopted for safety measures.

Company information
Hoshia Electric has established itself as a top manufacturer in various fields, including information display systems such as road information boards, industrial lighting known for its waterproof and explosion-proof features under the name "Water Pearl," tunnel lighting that began with the full-scale installation in the Kanmon Tunnel, and resin products represented by "Cutting Duct." As a new business, we started an electromagnetic noise countermeasure (EMC) product business in 1997 to address electromagnetic noise issues arising from digital devices. In the LED business, we successfully developed a blue light-emitting diode in April 2002 and a white light-emitting diode in December of the same year. Based on these technologies, we are actively expanding our business in the field of LED lighting fixtures, ranging from roads and tunnels to industrial lighting. On March 9, 2018, Hoshia Electric Co., Ltd. was listed on the Tokyo Stock Exchange First Section. In April 2022, we transitioned to the Tokyo Stock Exchange Standard Market. Moving forward, we will continue to leverage our creative thinking and technological capabilities cultivated thus far to develop even more innovative products and strive for business expansion.
