In this side by side comparison, the LightRail light mover is on the right and a stationary grow light is on the left. Notice how LightRail lights up all the plant, efficiently getting light to all the leaves, from one end of its run to the next. Compare that to the stationary grow light on the left and notice the hot spot on the top and the permanent shadows below. Those will never change on the stationary side. The photo tells the story – it’s the LightRail difference.
