Guidelines for lamp and lamps system manufacturers

In case of a luminaire without modifying optics and using one single lamp

the risk assessment of the lamp manufacturer is transferable to the final

lamp system or luminaire resulting in the same or a reduced risk.

Otherwise the lamp system (luminaire) manufacturer should perform the

re-assessment and assign the appropriate risk group.
