The standard diffuser installed. Classic Vusion™*
For outstanding light diffusion that artfully blends to the ceiling plane, select the Vusion diffuser. The fresh design harmonizes with most décors, yet provides the radiance of natural light.

Other diffusers were shown in place. I chose the standard with great light. Optiview was a really cool one...too bad it was not a partial cloudy day to see what it looked like...was tempted to get it, can change the diffuser in the future.
