In today’s age, the real score is acquiring and making use of light bulbs which can last longer. While you may have already come across the Nokero N100 solar light bulb which lasts two hours on a standard charge, it now has a successor in the N200 which can reportedly last longer and is water-proof at that.
The N200 lasts longer than the N100 and is good for up to six hours on a single charge. The bulb relies heavily on solar power and should be a great alternative for people gearing up for light sources running on another energy-rendering source.
The bulb will cost only $20 and lasts for about 2 years.
