Option [-20]:
•
this configuration is provided with 12 lenses mounted directly on Leds. Each lens emits a circular
beam with aperture of ~20°. A weaky diffusing window is placed in front of lenses. The purpose of
the diffuser is to reduce glare and homogenize the beam. This configuration projects a medium
beam of light. The pictures below show the light pattern at three different working distances.
