LIGHT DISTRIBUTION
Light distribution |
The light is dispersed at an emission angle of 58K.
A circle of about 2.2m in diameter (3.8 u) is illuminated at an average
of
500 lux at 2m from a cable terminal. |
|
(As a guide) |
Standard illuminance in a room;
1000 lux : sewing, manual-arts etc.
500 lux : reading and dining
200 lux : conversation, relaxation |
