Recently, Seiwa Electric Co., Ltd. Lighting Division Optical Testing Laboratory has been registered as a registered testing organization by the Independent Administrative Institution National Institute of Technology and Evaluation (NITE). The Registered Testing Organization System (JNLA) is a system that certifies whether a testing laboratory has the capability to present correct performance in accordance with the requirements for testing laboratories (ISO/IEC 17025) through document review and on-site inspection, ensuring that the quality system and testing facilities are adequate. Currently, among lighting fixture manufacturers, there are only four JNLA registered testing laboratories using the luminous flux measurement method (JIS C 8105-5), and Seiwa Electric Co., Ltd. becomes the fifth. Registered testing organizations under the JNLA system can issue test certificates and reports with a special emblem (symbol) in the testing registration category indicated on the registration certificate as proof of their registration.

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.
