A module of 400 LEDs and a diffusor plate positioned in front ensure an evenly illuminated area of 6x9cm. The adapter can be installed by the user. The condenser remains in the system. Electricity is supplied by an included 24V power supply unit. After your order has been confirmed, please send in the original Durst sliding latches for locking of condenser to Heiland electronic. The sliding latches are modified and returned with the LED cold light source.
