The first in the domestic industry: Emergency LED lighting equipment that can be used in explosion-proof areas. Certified by the Industrial Safety and Technology Association, approved by the Minister of Land, Infrastructure, Transport and Tourism, displaying the JIL mark.

The first in the domestic industry: Emergency LED lighting fixtures that can be used in explosion-proof areas Launch of explosion-proof emergency LED lighting fixtures (VZAA series) We have launched the first explosion-proof emergency LED lighting fixtures in the domestic industry that can be installed in explosion-proof areas where there is a risk of explosion or fire due to flammable gases or combustible liquids. Currently, emergency lighting fixtures defined by the Building Standards Act are limited to "incandescent lamps" and "fluorescent lamps," and the use of LEDs as emergency light sources has not been permitted. Therefore, while there have been LED emergency lighting fixtures that received certification based on the Minister of Land, Infrastructure, Transport and Tourism's certification system and passed the self-assessment of emergency lighting fixtures by the Japan Lighting Manufacturers Association, they could not be used in explosion-proof areas where there is a risk of explosion or fire. In response to the many requests for the use of LED as an emergency light source even in explosion-proof areas, we have developed explosion-proof emergency LED lighting fixtures that have passed type testing by the Japan Industrial Safety and Health Association, received certification from the Minister of Land, Infrastructure, Transport and Tourism, and display the JIL mark from the Japan Lighting Manufacturers Association, making us the first in the domestic industry to do so. Orders will begin on September 15, 2016. Since the JIL mark is affixed to the product, building confirmation procedures can continue to be carried out smoothly as before.

Explosion-proof LED lighting fixtures LZLA series, ideal for replacing incandescent lamps and circular fluorescent lamps in explosion-proof areas.

New Release of Explosion-Proof LED Lighting Fixtures (LZLA Series) Seiwa Electric Co., Ltd. has enhanced its lineup of LED lighting fixtures under the <Star Reds> series to meet diverse needs in the introduction of energy-saving equipment at various factories and initiatives for the environment (Minamata Convention). We are pleased to announce the addition of the new explosion-proof LED lighting fixtures "LZLA Series," which can be used in explosive hazardous areas Zone 1 and Zone 2, equivalent to incandescent lamps (100W, 200W) and high-output FHF32W (circular and compact fluorescent lamps). Orders will begin on May 15. The main body of the fixture employs aluminum die-casting, which excels in heat dissipation and lightweight design, allowing for effective heat dissipation measures. This increases the operating temperature range to -20°C to +50°C (compared to our conventional LED products, which are -20°C to +40°C) and enhances resistance to high-temperature environments. Additionally, it achieves a maintenance-free LED module lifespan of 60,000 hours while also possessing high durability and weather resistance.

Crittec Industries Co., Ltd. published a newspaper advertisement (black and white, full-page 15 columns) for the bridge expansion device "Hybrid Joint" in the February 26, 2026 issue of the Sankei Shimbun Tohoku 6 Prefectures edition. In Japan, the number of bridges over 50 years old is rapidly increasing, making the longevity of bridges a critical issue. The expansion devices, which are considered a cause of bridge damage, require high water-tightness and long-term durability. Our expansion device "Hybrid Joint" offers multiple types tailored to different bridge types and conditions. Among them, the "Hybrid Joint 3LII type" has demonstrated a durability of 100 years in fatigue loading tests conducted by a third-party organization. It has successfully passed 12 million cycles of repeated loading at a maximum load of 260 kN, confirming performance equivalent to a 100-year design service life for bridges. We have numerous delivery records in the six Tohoku prefectures and can accommodate a wide range of bridge types, including steel and PC bridges. The special website linked to the advertisement allows for the review of detailed materials and inquiries or requests for documents. Please make use of it for comparing and considering bridge renewal and repair plans. Crittec Industries will continue to contribute to the longevity of bridges nationwide, starting with the Tohoku region.

Born from the voices on the ground, high brightness × wide coverage × high cost performance linear lighting. To respond to the production site’s demands for "brighter," "wider," and "easier to use," we have launched the new high brightness linear lighting LLWK-N series, which balances high brightness and high cost performance. While achieving approximately three times the illuminance compared to the conventional LLWG series, we maintain an easy-to-implement price range. With a natural heat dissipation structure suitable for clean rooms and a compatible design that makes it easy to replace existing lines, we are thoroughly pursuing the "ease of use" required on-site. For detailed product specifications and inquiries about implementation, please feel free to contact us.

Our company not only sells building materials but also carries out flooring and wood deck construction within Okinawa Prefecture. For more details, please contact us. - Raised floor - Steel floor - Direct installation - Conventional floor - Recycled wood / wood deck
