Safety Information
• To avoid eye damage, don‘t look directly into the light source when turned on
Important
: The evaluation of eye safety occurs according to the standard CIE S009/E:2002 („photo biolo-
gical safety of lamps and lamp systems“). Within the risk grouping system of this CIE standard, the LEDs
specified in this data sheet fall into the „low risk“ group (relaying to devices in the visible spectrum with
an exposure time of 100 s). Under real circumstances (for exposure time, eye pupils, observation distance),
it can be assumed that no endangerment to the eye exists from these devices. As a matter of principle,
however, it should be mentioned that intense light sources have a high secondary exposure potential due
to their blinding effect. As is also true when viewing other bright light sources (e. g. headlights), temporary
reduction in visual acuity and afterimages can occur, leading to irritation, annoyance, visual impairment,
and even accidents, depending on the situation.
Intended Use
The LED ring lights of the RL4 series offer a standard diameter of 66 mm. They have been mainly
developed for lighting applications in the area of stereo microscopy. They provide a shadow
free, constant and flicker free light and are basically suitable for all types of microscopes and
cameras. With reducing rings the ring lights can be adapted to different diameters. The electro-
nic light control allows a balanced dimming from 0% - 100% with a memory function.
The ring lights consist of 48 long life, pure white, natural white or warm white LEDs. Alternati-
vely versions in red, green, blue and yellow are offered. As an accessory a frosted glass diffuser
creates as an option a diffuse light.
