Depending on the number of fixtures the LED modules will function at half (2 LED's).
one third (3 LED's) the luminous intensity. Moreover. due to different forward voltages
the current will not split in equal part.
Risk for an output voltage that exceeds the max for the LED.
A power supply that is switched on has max output on the secundary side (eg. 49V).
The LED in eg. a VARO is 7W works at 350mA and 20.1V.
49V is far too high for the VARO >> LED will be damaged.
