[Innovation] StudyLite – Rechargeable Study Lamp for Kids [Safe for Eyes, Solar Powered]

In Rural India, electricity comes for a premium and for that matter, even urban India is no exception.

BPL, in association with Sankara Nethralaya has designed a unique product called StudyLite that has been designed keeping students’ need in mind.

  • StudyLite works on 220V AC mains and rechargeable battery to provide light – helps in uninterrupted studying.
  • Has an option of solar power charging.
  • High performance LED light – no flicker/radiation/pollution
  • Rechargeable with upto 6 hours backup


Priced at Rs. 1,490 (premium?), the product took several parameters into consideration during the design – Luminance (optimum spread of light in study area), Spectral Power Distribution (to ensure colour temperature of light), Illumination (uniform, flicker-free lighting and right colour rendering index), and Radiation Effect etc (no harmful ultra-violet or infra-red radiation).

To make the design compact, we elected to use high quality rechargeable Nickel Metal Hydride(NiMH) battery packs. The battery packs are charged automatically when plugged to mains power with an over-charge protector to safeguard the batteries. This makes StudyLite convenient to use: there is no need for separate charging. The StudyLite can be kept always plugged on to AC mains. If power fails StudyLite will automatically switch over to back-up battery power to provide uninterrupted light.

Also, to take into account wide mains voltage fluctuations in many areas, we designed StudyLite to operate over a wide range of mains power: 100-260 V AC with an AC adaptor providing power to the lamp. To make StudyLite child-safe, we designed it to operate on a low 12 V DC system.

Impressive. What’s your take?
