Connecting LIVOLO VL-C700PIR Sensors to LED Lighting with Relays

A warm welcome and please advise.

I have 2 LIVOLO VL-C700PIR PIR motion sensors. The input of each is connected to a phase wire, while the output is connected to the coil input of a relay (connecting the sensors in parallel will break them if motion is detected on two at the same time).

The sensors control LED lighting powered by a constant-voltage power supply:
LED modular power supply 80W 6.7A DC12V IP20 ADLER Slim
Input voltage: 110-264V AC
Output voltage: 12V DC
Rated output current: 6.7A
Maximum load power: 80W
IP rating: IP20

Now the question is about the further connection (2 versions):
1) 230VAC/230VAC relays. Connect the inputs of the relay contacts to the phase and the outputs to the power supply (control by cutting off the power supply before the power supply)
2) 230VAC/12VDC relays. Connect the inputs of the contacts to the 12V output of the PSU, and the outputs of the contacts directly to the LED strip (control by cutting off the 12V power supply coming from the PSU).

Please give me a hint as to which solution would be better, or maybe some other solution I don't know about.

Regards.

Better by virtue of the economics would be to switch off the power supplies.

From an energy-saving point of view, it is indeed better to use solution number 1. However, there is a but. A switch-mode power supply, when switched off for a while, can draw a very high current. The relay contacts must be able to withstand it.

Thank you very much for your answers. I will apply the comments in selecting a suitable relay. Regards.
