It includes 4 energy-efficient LED lights, a solar panel, a control unit with a 12V battery, and all necessary cables and connectors. With a quick 4-5 hour charging time, this system provides 6-7 hours of reliable lighting, making it ideal for sheds, garages, stables, and more. ## Description This solar lighting system is ideal for places with no mains electricity such as outhouses, sheds, garages, farms, stables, as well as for camping, travel and any outdoor activities (e.g. for a yurt). The system is fully independent from the grid / AC power source and works purely based on sunlight energy. At daytime the 25W solar panel charges a 12V battery inside the control unit, which then provides power to 4 x 5W 12V LED lights connected via front sockets on the control unit. In addition, there's a standard 5V USB socket for charging mobile phones and USB compatible devices. The control unit has a built-in 12Ah battery with an automatic solar charge controller to manage the charging process and prevent overcharging. 25W solar panel supplied with the system can fully charge this battery within about 4-5 hours of bright sunshine (longer in cloudy weather), and the battery can provide enough energy to power 4 LED lights for continuous 6-7 hours, or twice as long if only two LED lights are connected. The system is very convenient to use and install: the solar panel comes with 10m cable (would suit most installations, as longer length is rarely required), and each LED light comes with 5m cable and an On/Off switch. All cables come with connectors for a quick "plug and play" installation. System specifications: - System voltage: 12V - Battery capacity: 12Ah - LED lights power: 5W - Length of solar panel cable: 10m - Length of LED lights cables: 5m - USB output current: 0.6-0.8A - Max DC output current: 3A - Control unit case size: 22x13x15 cm - Solar panel size: 51x35x2 cm - Control unit case weight: 6.86 kg - Solar panel weight: 2.35 kg Please contact Photonic Universe if you have any questions about this product. Review: Brilliant system, fantastic value and idiot proof to install. Don't hesitate, buy it, you will be very impressed. - Purchased this for our club boat house which is a relatively large multi room unit. The building is isolated and sits partly over water which is a very problematic situation requiring special provisions for safety if a normal power supply is installed, however as this is low voltage all those safety issues do not apply. Very easy to install, no electrical knowledge or skills are required. The pre fitted plugs and set cable lengths are a bit limiting for my needs but these are what makes it idiot proof for installing so I can see the reason for them being like they are. The system has been installed now for about 6 months and is better than I could have hoped for. The light output is very good, the building we use it in is not used for long periods so I cannot comment on the run time of the battery as we never get near the limits of the system but the lights are always fully bright. The lamps are LED so are plastic not glass so very tough plus they operate cold so there are no heat / fire issues to worry about when installing them. Overall the system is fantastic, simple to install and use, pretty much maintenance free and should give many years of service, I have no hesitation in recommending it, it is especially useful in the situation we have with a remote building in which we are not easily able to get power to and not permitted to to major changes to because of the lease condition. Review: Excellent power lighting system, easy to install too. - Excellent power lighting system. I bought this one for the wife's log cabin and she's really impressed as one light is enough to light up the cabin. My own cabin has the same brand but with a 100w solar panel which has been very reliable for the last 3 years. One reason I chose to buy this product again. Highly recommended. ## Features - Ideal for places with no access to mains electricity such as garages, sheds, outhouses, stables, barns etc. - Comes complete and includes everything you need for lighting: 4 LED lights, control unit with 12V battery, solar panel, cables with all switches and connectors. - Built-in solar charge controller protects the battery from overcharging - no need to disconnect the solar panel. - Control unit has USB port to charge mobile phones and power USB-compatible devices. - 4-5 hours charging time to fully charge the battery and provide enough energy for 6-7 hours of lighting … Scroll down to Product Description for more details. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00S1H7WRS | | Amperage | 3 Amps | | Box Contents | 4 LED lights, control unit with 12V battery, solar panel, cables with switches and connectors | | Brand | Photonic Universe | | Brand Name | Photonic Universe | | Compatible Devices | USB-compatible devices | | Compatible Phone Models | USB-compatible smartphones | | Compatible devices | USB-compatible devices | | Compatible phone models | USB-compatible smartphones | | Connectivity Technology | USB | | Connector Type | USB Type C | | Connector type | USB Type C | | Country of Origin | China | | Current Rating | 3 Amps | | Current Type | DC | | Customer Reviews | 4.6 out of 5 stars 209 Reviews | | Enclosure Material | Plastic | | Included components | 4 LED lights, control unit with 12V battery, solar panel, cables with switches and connectors | | Input Voltage | 12 Volts | | Item Weight | 6.86 Kilograms | | Manufacturer | Photonic Universe | | Manufacturer Part Number | SL-25W | | Model Number | SL-25W | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Power Levels | 1 | | Output Current | 3 Amps | | Output Voltage | 12 Volts | | Plug Type | No plug | | Portable | Yes | | Power Plug Type | No Plug | | Power Source | Battery Powered | | Product Features | Travel | | Special feature | Travel | | Total USB 2.0 Ports | 1 | | Total USB Ports | 1 | | Unit Count | 3.0 count | | Wattage | 25 watts | ## Product Details - **Amperage:** 3 Amps - **Brand:** Photonic Universe - **Compatible devices:** USB-compatible devices - **Compatible phone models:** USB-compatible smartphones - **Connector type:** USB Type C - **Included components:** 4 LED lights, control unit with 12V battery, solar panel, cables with switches and connectors - **Input voltage:** 12 Volts - **Special feature:** Travel - **Total USB ports:** 1 - **Wattage:** 25 watts ## Images ![25W Off-Grid Solar Lighting System with 4 x 5W LED Lights, Solar Panel, Battery and Cables - Complete Solar Lighting Kit for a Shed, Garage, Outhouse, Stables, Barn, Vehicle or Boat - Image 1](https://m.media-amazon.com/images/I/71QCr-eVauL.jpg) ## Questions & Answers **Q: Can you buy a longer cable than 10 meters?** A: Hello, Thank you for your interest in our solar lighting kits.

Highly recommended. ### ⭐⭐⭐⭐⭐ 25w off grid solar lighting system *by R***M on 5 December 2022* After buying cheaper systems, decided to buy this system. I can say it is well worth the extra expense. Simple to set up. There is a good length of cable from solar panel to control unit, and a sensible length on the bulb cables, with in line switches on each bulb cable, just plug everything in turn on the control unit and leave it to charge and use bulbs as required. Even in these dull Nov/Dec days the solar panel is keeping the battery well charged, and the bulbs are nice and bright. Highly recommend this system, early days, but am very happy with this kit. Also, after a slight problem, contact with the seller was quick and easy and sorted quickly.
