Hoshi and Electric Co., Ltd. has been supplying lighting fixtures for numerous roads and tunnels since 1957, when it delivered lighting equipment for the Kanmon Tunnel, the world's first underwater tunnel at that time. Road lighting fixtures are mounted on poles, but these poles tend to accumulate moisture, leading to condensation and water droplets. Our company offers a product that protects electrical wiring from moisture and water droplets: the pole-mounted junction box (SB series), which has over 40 years of proven performance. We are now launching a new addition to our lineup, the "Junction Box with Internal Wiring for Poles" (SBJA series), which makes internal wiring for road lighting fixtures safe and easy. The "Junction Box with Internal Wiring for Poles" (SBJA series) has a protection rating equivalent to IP68 against water and dust, making it ideal for the moist environment inside poles. It comes with pre-wired connections that allow for safe and easy installation, and it is also easy to inspect. The junction box has a sealed compartment for the breaker and terminal block in some specifications, protecting the electrical wiring from moisture and water droplets that may accumulate inside the pole. Additionally, the top cover can be opened for voltage and insulation resistance measurements.

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 demonstrate correct performance in accordance with the requirements for testing laboratories (ISO/IEC 17025) through document review and on-site inspection. Currently, there are only four registered testing laboratories for photometric measurement methods (JIS C 8105-5) among lighting fixture manufacturers, and Seiwa Electric Co., Ltd. becomes the fifth. Registered testing organizations under the JNLA system can issue test certificates and performance reports with a special emblem (symbol) in the testing registration category indicated on the registration certificate as proof of their registration. As a publicly recognized testing organization with stable quality, we enhance the Seiwa brand and ensure that our customers can use products of stable quality. We will continue to conduct measurement tests based on the JNLA registration system, providing reliable performance indications to our customers and striving for the appropriate dissemination of LED lighting fixtures and the creation of even more reliable products.
