The lighting tube can be used for 10000 hours, and that is 60 times of the existing thermal lamp; greatly saves the cost of replacement. Low temperature of tube surface makes almost no temperature rise of the irradiated object. Only three visible colors: light-red, green and blue; no infrared ray, ultraviolet ray and so on thermal radiation sources. Compared to the thermal light, it can save electricity more than 70%. Exact color temperature and high color reproduction rate. Without strong dazzling makes people feel comfortable and relative. Light body is made of aluminum; barndoor uses imported reflector and achieves a high reflective efficiency. The main parts of lamps all use internationally known brand equipment, high quality and stable performance.
