If you plan to hang the garland outdoors, it is important to find a model with at least IP44 protection, a long and strong wire made of rubber or silicone.
Therefore, cheap PVC is not used in street garlands, as in interior garlands. Wire for street garlands is made of silicone, rubber, rubber or special PVC with the addition of silicone or plasticizers that increase flexibility and frost resistance.
When decorating trees, garlands and light products of the same type can be used, or combined options when a tree is decorated using different types of garlands and other light decorations. It doesn't matter how many trees are in the area.
Coniferous trees are decorated with garlands arbitrarily, since it is impossible to wrap the trunk and individual branches around them. It is important to evenly distribute the LED threads over the entire surface from the crown. You need to place the garlands so that the wires are hidden in the needles.
If the plans do not include the inclusion of garlands in spring, summer, autumn, then it is better to order the dismantling of lighting equipment. Any LED product, whether it is Play-Light rain, Clip-Light, a light grid, an ordinary garland, will last much longer if you turn it off and remove it from the street for the summer, and it is better for tree growth.
