discussing projects and some stated that he was having trouble finding and economical 12V timer and that all the timers he could purchase required mains supply.
The situation is solar panle charges a SLA battery that runs a few 12V leds for a porch light each evening.
I redefined it to needing a circuit that responded to ambient light dropping and then switching on some LED lights for a set period of time, say 2-4 hours, thus removing any need for a "timer" and Rt syncing/drift.
Has anyone come across such a circuit?
