If you are looking to replace the conventional lamps which have been lighting up your village or looking for an eco-friendly option during power cuts, the Tata Solar Diva™ 4L could be a solution.
Tata Solar Diva 4L is a portable solar lantern. It consists of a 0.7 Wp solar module, a 3.7V-630mAh lithium-ion battery and a 0.5W LED light. It also features 3 modes of operation (dim, medium, and bright), multiple mounting and hanging positions for different applications, and a micro USB port for charging the light from an AC source (a power plug).
The maximum continuous operation is for 8 hours and a full battery charging time is also 8 hours. The Tata Solar Diva 4L has a lightweight design for easy portability, adjustable brightness settings, over-charge, over-discharge and short-circuit protection, and indications of the battery’s state of charge.
The lantern comes with the integrated solar module and has a frosted LED cover for glare-free light. It can be used for multiple domestic applications, but is well suited for outdoor activity as well.
