The movable light bar can be used to freely adjust the light density at different points within the effective coverage area, maximizing light utilization and creating an even crop.At the same time,each lamp bar can run independently, it is easy to install, store and replace,the maintenance cost is extremely low.

Each lamp strip is equipped with an aluminum shell and cooling groove, good cooling means lower ambient heat, thus avoiding damage to plants.Generates less heat and reduces cooling costs by 50% due to the large area of the aluminum heat sink and slim passively cooled bars!
