Why move your light?

Moving one light on a 6 foot rail should increase your light's area of coverage by approximately 1.6. This translates into lower operating cost due to higher single light yields. The lumens produced by a grow light decrease the greater the distance from the bulb. To avoid plant killing heat associated with stationary grow lights, the bulb must be kept at a greater distance from the plants. For example, your plants end up getting far less lumens than you are actually paying for. By moving your light, you may run a tighter plant to lamp tolerance (using more of what you are paying for) without generating plant killing heat. Again, this translates into lower operating cost through higher yields. Moving your light from one end of your garden and back will give your garden light at a much greater variety of angles. This allows more light to reach the foliage at the bottom of the plant, which is normally shaded by the foliage at the top of the plant. As a greater portion of the plant takes part in the process of photosynthesis, lower operating costs result from greater yields.
