Now electricity shortages often blackouts, to people's lives a lot of inconvenience, especially in the summer, an easy power, and the other is very abundant sunshine, so in the evening, you simply do not worry because of power outages and missed homework or other study thing. This lamp can provide long efficient lighting.
(4) Long Life Lamp - Low-voltage low current power supply, light coefficient is much smaller than the fluorescent lamp.
Low power consumption and high brightness LED lights astigmatism high-tech products are environmentally friendly, just a low voltage low current supply can be, it's life 10 times longer than fluorescent lamp, 100 times longer than incandescent.
(5) Low Safelight - low voltage power supply no security risks
9V voltage power supply, there is no problem cause harm inadvertently lamp and other use. Especially active child, even bare hands to touch the lamp inside the wire connectors or sheet metal, nor any of electric shock. Very safe. (6) Environmental
Internally uses a lithium ion battery, in line with the requirements of international environmental conventions, it can be used repeatedly. Use inexhaustible, with the incessant clean energy - solar energy, energy saving and environmental protection, no secondary pollution.
Five of the original selection
1, solar panels choose
Currently photoelectric conversion efficiency of silicon solar cells is about 15%, up to 24%. Is all kinds of solar cells, photoelectric conversion efficiency of the highest, most mature technology. Life in general up to 15A, up to 25A. Polycrystalline silicon solar cells than the photoelectric conversion efficiency of monocrystalline silicon solar cells to reduce the number, the photoelectric conversion efficiency of about 12%, while the polycrystalline silicon solar battery life is also shorter than the monocrystalline silicon solar cells. Amorphous silicon thin film solar cell is low photoelectric conversion efficiency.
