Can I connect a mains AC lamp directly to the relay?
Check the relay contact rating printed on the module, since the listing does not state it. For mains loads, use a relay module rated for that voltage and current, with proper isolation and an enclosure.
How do I wire the load to the relay?
Power the module at 12V, then connect the load through the relay's COM and NO or NC contacts. Choose NO if the load should be on only in darkness, or NC if it should be on only in light, and confirm the logic on the module's labels.
