For areas where extra impact strength is required. The standard Acrylic Dome suits most applications, but can be replaced with a Polycarb Dome if required.
For areas where major differences occur between Summer & Winter Light Levels. Use the standard diffuer in Winter, and the Opal in Summer to slightly reduce output.
155mm High Ring required in most units. It fills the final gap between the Rigid Lengths and the Ceiling Parts. A warehouse kit does not use this component.
