range
UV components of OSRAM DULUX
Ultra-violet radiation can have desirable effects (such as tanning) and undesirable
effects (such as sunburn) on the human body. The intensity of these effects depends
on the irradiance level and the period of exposure.
In the case of lamps intended for general lighting applications, lamp and luminaire
manufacturers must ensure that there is no possibility of any harmful effects even
under high illuminance levels over a full day.
The table shows that OSRAM DULUX
for any additional protective measures.
If light-sensitive materials are exposed to this light for relatively long periods, there
may be some change in colour (bleaching, for example). In OSRAM DULUX
this effect is caused primarily by UV-A radiation.
Lamps with low UV-A components or low illuminance levels should therefore be cho-
sen for illuminating light-sensitive materials.
