Irradiation Range:With three stage raising and lowing mast, the maximum extension of the mast is 2.8m. The mast as the axis is able to do 360°turning so that to realize the irradiation at any angle. Power Supply: two power supply methods. Using generator power supply, it works continuously over 6h with full tank gasoline; using 220V main supply could realize long time working continuously. Operate easily: With separate smart button to control on/off of the two lamps and convenient to adjust the height of the mast manually;the lamp consists of two main parts: the lamp holder (including the lamp panel and mast) and the generator stand (including generator, electric case and generator base). It is convenient to assemble, disassemble and transport. Operate easily and with excellent applicability. Service Environment:Adopt multiple shockproof structure design, excellent anti-shock performance and could use reliably in the high frequency shock environment.
