1.Luminance (cd/m) measurement: The luminance of 9 points on the lighting area 1.measured and averaged.
2.Illuminance (lm/m) is obtained by multiplying 3.14 to brightness.
3.Uniformity is obtained by dividing minimum luminance by maximum luminance from 9 1.point measurement.

Thanks to its characteristics of no maintenance, long life of more than 10 years and wide operating temperature range, it can be installed anywhere. Installation itself is very easy. Different from 12V low voltage lighting requiring wiring, it can be placed anywhere you want it to be without range constraints of wire. When it is installed on the surface of garden, driveway, garden path or any place, it will not only beautify the landscape but also guide the pedestrian traffic or light vehicular traffic.
