LIGHT DISTRIBUTION

Light distribution
The light is dispersed at an emission angle of 58K.
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
