The Iris table lamp transforms its form and the atmosphere in a room by changing its light direction and projections. By adjusting this lamp you can have an up light, a down light, or mixture of both. The reflective interior of the this table lamp casts intricately patterned reflections that change as the lamp's configuration is changed.This animation shows the range of way the brass table lamp's light can be adjusted:http://vimeo.com/78166393(Please note that the table lamp is not controlled remotely, but is easily adjusted by hand.)The Involution Lamp is the fruit of years of development of the patented overlapping leaves mechanism, first explored in lightexture's Steamlight series. (Patent #8,025,430) Composed of overlapping brass leaves, each Involution Lamp has two adjustable apertures; as one opens, the other closes. When the lower aperture is fully open, light shines directly down, creating a circle of textured golden light on the surface below. When the upper aperture is open, patterned light shines upward and bounces off the ceiling to fill the space with a warm, indirect light. The transition between these two provides a variety of reflections and light atmospheres.We offer the Iris Table Lamp with a 7W LED bulb that gives a very strong light and is extremely efficient in its power consumption and environmentally friendly. This MR16 LED light bulb has an average life of 30,000 hours - That's about 30 years of regular use.size: 8"L x 8"D x 15"HBlack braided electrical cord with a white woven accent.All electrical parts are UL recognized.
