In an endeavor to bring light to areas facing perpetual power shortages, L&T has developed a unique solar-powered portable lantern D.VA popularly referred to as ‘Diva,’ which is capable of emitting uninterrupted light for up to 10 hours at maximum brightness and as much as 40 hours in night mode, when fully charged. Conceived indigenously by the design team of L&T Electrical and Automation, this rechargeable off-the-grid innovative device offers several significant advantages over conventional solar lanterns.
D.VA can be charged through dual modes. Users can either harness sunlight and charge the device through solar panels of 5W rating, or use a regular mains (AC supply) charging adaptor in low or no sunlight conditions. Life span of the solar panels typically ranges between 20 and 25 years, while its high bright LEDs have rated life of up to 50,000 hours.
Even with a power consumption as low as 2W, the uniquely designed metalized reflector of D.VA produces an output equivalent to a traditional 25W incandescent bulb or a 5W CFL. Also, its 360-degree uniform illumination is glare free and soothing to the eyes.
It is also equipped with salient features such as mobile charging and smart 4 LED battery status indicator.
This rechargeable off-the-grid innovative device is the recipient of India Design Council’s India Design Mark award (IMark) for good design.
