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. |
