We are fans of the Nokero solar light bulb and enjoyed our time with the Nokero N100. As with most things, improvement comes along. The Nokero N200 looks better (IMHO), lasts three times longer, and is 60% brighter. A detailed comparison of the Nokero N100 vs the Nokero N200 after the break.
The bulb can last six or more hours on one day’s charge, or 2.5 hours per night or more in Turbo-Task mode. The Nokero’s N200 single solar panel can be pivoted toward the sun to maximize charging efficiency in the day, and at night the light can be hung, or set inside to provide light.
