Artsy and different, here are some more uncanny lighting solutions that you can consider for your home. They are called ORB lighting, spherically made lamps which come in either table or floor type variants.
The lamps are supported by three legs which appear to pierce through it to provide the necessary stability and support. The aluminum feet are practically the same, something perhaps made to cut down production cost.
The inner metal component keeps the whole assembly together. By screwing the feet in, the two glass halves are kept in place with no pressure on the glass component. The inner metal component also acts as support for the light bulb fixture or LED system.
Access to the inner components is easily facilitated by removing the top glass sphere half which is easily removed by unscrewing the upper aluminum components.
