The default plug-flat plug (US standard), please note if required.   Wire: new material PVC parallel transparent wire, wire diameter 1.6mm, 0.1 square pure copper core, applicable environment: -40℃±60℃, lamp tube spacing 30cm, distance between plug and last lamp tube is 3.8m, wire length can be Made to order.   Light board: high-quality FR-4 double-sided board, thickness 0.6mm, width 6mm, genuine lamp beads SMD2835, 0.1W, double-sided light   Pipe: New material thickened transparent PC pipe, 17 g/m, pressure resistance, cold resistance, high temperature resistance, non-atomization, and weather resistance.   Color: red, yellow, green, blue, white, warm white, pink, ice blue, colorful, segment color,   Packing: neutral color box, 30cm long 20 sets/carton, 50cm long 20 sets, 50 sets/carton two kinds, 80cm long 20 sets, 25 sets, 50 sets/carton three outer boxes, warranty 12 month.   Instructions for use: It can be used indoors and outdoors, not afraid of rain, do not soak in water, conventional installation cannot be reversed, it needs to be customized, according to our years of production, maintenance and customer feedback information, we come to: this product is the largest The weakness is that most of the lamps do not have a suitable fixed point during use. They can only be hung in the air by the outlet of the lamp and swayed by the wind, causing the wire to be pulled. As time passes, the outlet of the lamp plug will easily break the copper in the wire. Wire (not visible on the surface) leads to poor contact or no light. It is recommended to fix the lamp and power supply as much as possible during installation. The windy place, especially the place near the sea, if the installation place is not good to fix the lamp, the lamp will keep swinging. It is not recommended to use, it is easy to damage. This is a common problem of similar products. The thicker wire is relatively stable and durable. The difference between the engineering model and the economic model: the power supply scheme is different, one is 12V, the other is 7V, do not use power randomly, wire size is different, lamp thickness (hardness) is different, circuit board thickness width is different, lamp beads number, brightness is different Same, same packaging, product photos
