By adjusting this lamp you can have a downward spot light, & upward reflected light, or a mixture of both. The reflective interior of this hanging lamp casts patterned reflections that change as the lamp's configuration is changed.

(Patent #8,025,430) Composed of overlapping brass leaves, each Iris Lamp has two adjustable apertures; as one opens, the other closes. When the lower aperture is fully open, light shines directly down, casting a broad spot light onto the surface below. When the upper aperture is open, textured golden light shines upward & a small spot light shines downwards. The transition between these two provides a variety of reflections & light atmospheres.
