20 Watt Solar Street light For Home Gardens, Outdoor, School Campus, Highways
Check COD Availability (upto Rs. 5,000)
Loom Solar-20W is LED solar street light with inbuilt Lithium ferro phosphate battery. This solar light have controller is integrated with LED driver. And this also can save the cost of Led driver. The maximum conversion efficiency reaches 96%. The output current can be adjusted for 4 time frames. With fully sealed waterproof design and wide output voltage has better efficiency.
Features:
- Adopt the integrating technology of control and constant current, and save the cost of the LED drive power supply for users.
- With the function of 4 time frames power regulation, Users can dim LED lamps’ output power.
- The controller adopts fully sealed waterproof design. The IP grade reaches IP67. The controller can be used in the water.
- Flexible and adjustable working parameter makes the controller adapt to different solar systems.
- This light can withstand from -35℃ to 80℃ high and low temperature, so it can adapt to extreme temperature.
- Loom Solar-20W has an optional function that the controller can automatically drop load’s power when battery is lower than 12.5V. This function let the lights work for longer days in rainy season.
- Another optional function of Loom Solar-20W is that it can adjust the working time automatically in different seasons. In winter, the working time becomes long, while in summer, the working time becomes short automatically.
Installations:
- Connect the battery to terminals. At the moment, the IDLE indicator is on. After 30 seconds, the lamp is turned on;
- Connect the solar panel to the controller. If at daytime, after 70 seconds, the CHARGE indicator is on and the lamp will be turned off
Notes:
- Please connecting wires in order. Wrong wire connection lead to system’s misjudgment and controller’s damage.
