Lighting design by supporting surface material classification: Indoor proof lighting may be installed in a number belonging to the ordinary combustible material surfaces, such as wood walls and ceiling, they do not allow installation of explosion-proof lighting surface temperature exceeds a safe value. According to whether the explosion-proof lighting can be installed directly in ordinary combustible materials can be divided into two classes surface. One for the only suitable for installation in a non-combustible surface lamps. Another is suitable for direct installation in ordinary combustible materials, surface-proof emergency light fixtures offer, marked symbols. In addition, according to the installation can be divided into fixed, transportable, and portable. Applicable environmental enclosure is made of special high hardness alloy materials, multiple damping structure and integrated design, sophisticated design and surface sealed, with a strong shock and impact resistance glare-proof emergency lights, emergency lights, explosion-proof durable, anti- dust and corrosion, can be used in harsh outdoor environments and long-term. Convenient boom-mounted, ceiling and wall mounting, easy to operate. Technical parameters Rated voltage (AC) 220 V power source MH / HPS gas discharge lamp luminous flux of 250 W MH HID lamps 22000 lm HPS gas discharge lamps 28500 lm gas explosion-proof emergency lights, Koretoyo proof (certified), Xiqing proof emergency lights by Zhejiang Koretoyo explosion-proof electrical Co., Ltd. Tianjin offices. Zhejiang Koretoyo explosion-proof electrical Ltd. Tianjin Office (#) is Tianjin, explosion-proof lighting leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
