At present, three luminous floodlights are so popular in the market. You just change them to one side. The waste of materials cannot improve the selling point. Brother, you should not be a professional designer of lamps. In this way, no customer dares to produce them. Moreover, they use lampshades, which look like wall lamps. However, according to this design, the cost of wall lamps is several times higher, and no customer produces them at all. Finally, I thought for a moment, you should use this to cheat those who don't know how to do it.
