How to choose solar light bulb

　　The techniques for selecting solar light bulb are as follows: First, panel size, according to the space size, generally large panel solar light bulb irradiation range is wide; Two, the battery size, the larger the battery capacity, the longer the battery life; A solar light bulb is made up of a number of small bulbs. The more bulbs, the brighter the bulb. Four, lampshade material, you can choose metal material, relatively stable; Five, the selection of performance, solar light bulb is generally used outdoors, so choose waterproof and lightning proof effect.

　　1.Panel size

　　The panel selection of the solar light bulb is determined according to the size of the space to be illuminated by the solar light bulb and the individual's needs. Generally, the larger the space, the larger the panel should be, so that the panel can absorb more light and provide more electricity. Common panel sizes are 19 cm x22 cm, 24 cm x35 cm, 35 cm x35 cm, 35 cm x46 cm, panel size will also affect its power and conversion rate, in ordinary life, choose the conversion rate can reach more than 18% is actually enough.

　　2.Battery size

　　It works by trapping the sun's heat through a panel, which converts it into electricity stored inside a solar cell. So generally, the larger the capacity of a battery, the more energy it will store and the longer it will last. Therefore, if you want to use solar light bulb for a long time, it is recommended to choose a large battery capacity, its capacity size, but also pay attention to the number of internal batteries, generally three to four batteries, its battery life will be relatively longer.

　　3.Number of bulbs

　　The inside of a solar light bulb is made up of a number of small bulbs. Often the more there are inside the bulb, the brighter the amount of light it can emit. And in most cases, the more bulbs inside the bulb, the larger the volume of the solar light bulb. So when we choose, we should look at the specific situation or consult the business to see how much solar light bulb is needed to illuminate the area of our home.

　　4.lampshade material

　　There are two common lampshade materials, one is plastic material, the other is metal material, in general, it is recommended that you choose metal lampshade, because metal lampshade in the case of luminescence heating, not easy to damage, the overall will be more stable, such lampshade its service life will be longer, In addition, we should also pay attention to the choice of light transmittance better lampshade.

　　5.Select performance

　　When purchasing a solar light bulb, pay attention to whether it is waterproof and lightning proof, so that it will not burn out or even cause electric shock in some thunderstorms, and pay attention to the installation of ground wire when connecting the solar light bulb.
