This will connect power during the day and will disconnect power at night. **Q: Making a fountain 12v led strip light w/12v nimh battery & solar panel. is this usable for dusk to dawn operation?** A: should work, I have been using it to control my outdoor lights. works great **Q: I am looking for a adjustable photocell that runs on 120vac will this work.** A: If I understand your question correctly, no, this unit requires a 12 volt power source. Yes, it can switch 120 vac circuits. **Q: I received the item without any instruction. Where can i find it?** A: Online. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great switch! *by M***L on August 15, 2018* I have this wired to turn off a pump at dark and it works extremely well. Hard to find a 12V NO/NC photocell switch and I was very pleased to find it works so well. Highly recommended. ### ⭐⭐⭐ Due to the power draw on this board I would not recommend use for small solar applications *by D***Y on June 26, 2018* It does work with a 12 volt power and there is an extra connection port for opposite use: power on in daylight and no power at night. I was trying to use it for a light on at night powered by batteries charged by 12 volt 1.5 watt solar panel during the day. The Esmusky relay board draws 42 mA at 12.5 volts at night and discharged my 12 1000 mAh NiCd battery pack in a few hours even with no load ( no light ) attached to the board. Due to the power draw on this board I would not recommend use for small solar applications. I would l only use this for 12 volt plug in power supplies. ### ⭐⭐⭐⭐ Very compact unit that works great to control my outside low voltage light system *by H***B on July 24, 2018* Very compact unit that works great to control my outside low voltage lighting system. I connected it in series with a timer to save energy (to turn lights off during the wee hours). A few gripes: I wished the screw terminals were a bit bigger. The power supply to the board is via two pins and I didn't have suitable plug so I soldered a couple of wires to the pins and used shrink tube to prevent accidental touching as the pins are very close together. Not a big deal, but would have preferred a couple of screw terminals for the supply mains. I am a bit confused why they mark these two pins in English with VDC and GND and the output relays in Chinese. No instructions are included but the connections are easy to figure out: The center screw terminal is the common, the left NO and the right NC. LED's are a nice touch (red is power on, green is on below the light threshold) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/17878041-dc-12v-auto-on-off-photocell-light-switch-photoswitch-light](https://www.desertcart.co.uk/products/17878041-dc-12v-auto-on-off-photocell-light-switch-photoswitch-light) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-06*
