This is a smaller light with a Voronoi design outer cage. It printed in 11 3/4 hours at a layer height of 0.200 mm.
The light is designed to hold a standard LED puck light; search for "LED puck" and you will find several options. The light has a space for accommodating the cord for a wall-powered LED.
Several people have asked what software I use to design the models I upload here. I made a blog page that gives the answer: http://birkbinnard.com/blog/parametric-modeling/
