Battery-powered remote photocell sensor (range 300 ft)
Programmable astro clock with sunrise/sunset times
No wiring to existing control cable needed

Target Users: Electricians working on commercial or industrial lighting retrofits where existing control wiring is inaccessible or impractical to trace

Revenue Model: $89/unit for the relay module, $29 for optional remote sensor; volume discounts for electrical contractors
