Can Iodine Tungsten Lamp Be Used on the Construction Site?

Iodine tungsten lamp is not allowed to be used on the construction site. Iodine tungsten lamp is an improved version of incandescent lamps. Its principle is similar to that of incandescent lamp. A chemical combination reaction occurs at the lamp wall, and the sublimated tungsten on the lamp wall and other parts of the lamp tube is recycled to the filament and sublimated at a relatively high temperature (above 1200-2000℃) so that the filament will not burn out quickly due to high temperature.

Therefore, iodine tungsten lamp has the characteristics of large power and large quantity and is widely used in large occasions such as cinematography, stage square, etc. However, iodine tungsten lamp still has the problem of high heat, and it is dangerous to use them on specific occasions, such as wiring, cable support, and installation height on the construction site.

China has conducted a detailed assessment of the safety of iodine-tungsten lamps used on construction sites. According to the "Technical Specifications for Temporary Electricity Safety at Construction Sites" (JGJ46-2005) and "Technical Specifications for Fire Safety at Construction Sites of Construction Projects" (GB50720-2011), most of the power cords of iodine-tungsten lamps on the construction site are two-core wires. At this time, both ends of the power supply are outside. In the absence of PE wire protection, it is very easy to cause electric shock and fire accidents due to the lack of rain protection.

Since the use of iodine tungsten lamps on the construction site has major safety hazards, it has been decided to prohibit the use of iodine tungsten lamps on this occasion. Generally, lawn lights, running lights with safety nets, 36V safety voltage lighting lamps, or other suitable construction lights can be used. Electrical specification for lighting electrical as an alternative. In production and living places with combustibles, cold light sources such as LEDs should be used as high-intensity, long-term lighting, and standardized installation and use should be achieved.
