Compared to the previous versions, the new lights stimulate more fluorescence in the corals. The diffusion plate called ‘light guide’ now features four non-diffuse areas with white leds behind these. This feature enables the light to produce a subtle shimmering effect while still avoiding any ‘discoballing’. The tank is lit as even as it would have been lit with a large bank of T5 units while still featuring some shimmering. Especially when the lights are mounted close to the water surface, this subtle shimmering effect is clearly visible.
