Product specifications Construction kit - Blue Fan Item description Construction kit - Blue Fan Item number 4037373104505 Occasion Birthday, Sinterklaas, Christmas Hobby Crafts & Drawing Suitable for age 8-12 years, 13-17 years Country of origin Germany 10450_Solarlüfter.pdf 2 Volt solar cell Solar motor with holder Large fan Not suitable for children under 3 years. (Contains many small parts that can be swallowed) Required light conditions: One thing must be said upfront: in dark or poorly lit rooms or with light sources such as neon tubes and energy-saving lamps, every solar cell generates very little power, and the motor cannot start because the supplied power is too low. However, as soon as sunlight or halogen light illuminates the solar cell, the solar cell generates enough electricity for continuous movement. A model can also be operated with a powerful flashlight, but the flashlight must be very close to the solar cell! So it's better to put it in the sun or have a halogen lamp handy, and you will get amazed looks and lasting insights.
