• Recommendation: Please use loads and types of one producer.
• The dimmer interface is not standardised, it is the responsibility of the lamp manufacturers to list compatible products in their manufacturing information. Different installation situations can lead to different results. To clear up the problem, for example, it is recommended to carry out a local test of the selected lamps and dimmers. Please consult the lamp manufacturer for the LED dimmer recommended.
• A liability on the part of Busch-Jaeger for the compatibility of the allocated lamps and dimmers is therefore excluded.
