NSC9720A through street NSC9720A NSC9720A purchase NSC9720A glare through street Contact Applications: l used in factories, workshops, warehouses, stadiums and other plants, stadiums, railways, roads, bridges, tunnels and other places for emergency lighting fixed. Structural characteristics: l-efficiency gas discharge lamp as the light source, high luminous efficiency, no flicker, no glare, long life, the average life of 10,000 hours; l design and use of protective angle prism technology transparent parts, soft lighting, anti-glare effect, can effectively reduce the operation, construction workers eye irritation, avoid discomfort and fatigue; l use of wide voltage, constant power technology and a special circuit design. A type can be used as a normal task lighting, but also has emergency functions; B type purely as usual emergency lighting is turned off. A, B-type when the main power failure can immediately launched the emergency lighting, can also be controlled at any time during a mains power failure started with an external switch; l Multiple anti-vibration design and high-strength alloy casing, to ensure its tracks in the roadbed, tunnels, bridges and culverts and long-term safety of high frequency vibration; l special sealing materials and surface coating, to ensure that lighting in the humid, high temperature corrosion and other harsh environments never, never rust.
