Repeated folding is uncommon in practice, but when it does, the folding joints are engineered to maintain strength. During use, the grow light is directed downward toward the plants, and the frame is subjected to a uniform load (its own weight), with the largest bending moment occurring at the central joint. There will be no downward deflection or deformation after the hanging ropes are fitted, thanks to high-strength bearings and a 180° stop design. V3 LED grow light was confirmed by mechanical calculations performed throughout the early stages of product design.
