Application: XB-ZFG1L is vertically installed light and can be boundary marking of touchdown and lift-off (TLOF) area. The product provides unidirectional steady-burning white light, which supplies floodlighting for helipad surfaces. As using the product, the average surface illuminance of the touchdown and lift-off (TLOF) area will not be less than 10LX and uniformity ratio (the ratio of the average illuminance and minimum illuminance) will be less than 8:1, which allows the helicopters landing safely. Patents: Developed product and owns independent intellectual property rights for product Optical lens which is solely developed by our company and used at product is patented as invention. Patent number is 816343 Features: As result of using patented optical lens in product and applying single high efficiency LED as light source, product obtains: Brilliant optical effects Very high efficiency of light source conversion Evident effect of energy-saving Rated power: 20W As cooling and structural parts of product are made of lightweight aluminum alloy and unique structure of cooling focuses on dealing with conduction, convection and radiation at same time, the product processes: Nice effect of cooling Lightweight structure Small size 1.5kg weight Easy to transportation and install As to driving features of LED lights, driving power is used for product, which leads to: Wide working voltage input (input voltage: 100 to 250V AC) Constant current output Brilliant stability of driving Long service life Compliance with standards: Technology standards for Civilian Heliport(MH5013-2008) ICAO Annex 14 Vol II (Heliport) Warranty declaration: Equipment have three-year quality-guarantee and five-year maintenance-guarantee Man-made damage or force majeure voids warranty
