Embodiments of the present invention provide a method of dynamically transitioning into a distinct display format during unusual attitude conditions. In order to mimic the size and appearance of fluorescent bulbs in existing troffer-style and surface-mount fixtures, LEDs are may be arranged on light bars with integrated lenses to both diffuse the light and shape the output beam. The gate member contacts the upper surface of flowing bulk material and moves up and down in response to the flow of bulk material through the chute to restrict the flow of air to reduce dust. The first beam of light may spill onto the second target area, and the second beam of light may spill onto the first target area.
