I have also taken a combination of lightbulbs, cheap bells from a craft store that I patina-ed with food coloring, pieces of glass with a hole drilled in with a dremel (immerse the piece of glass in a container of cool water and drill – the dremel is totally fine as long as you only submerge the drill bit portion- I set my glass on a piece of of wood and drilled right through, without harming my container), and old keys, and hung them from a wire “tree” by pieces of coiled up copper wire – makes a very interesting conversation piece, alternative christmas tree, or just a piece of art.
The United States Environmental Protection Agency 's Energy Star program in March 2008 established rules for labeling lamps that meet a set of standards for efficiency, starting time, life expectancy, color, and consistency of performance. The intent of the program is to reduce consumer concerns about efficient light bulbs due to variable quality of products.  Those CFLs with a recent Energy Star certification start in less than one second and do not flicker. Energy Star Light Bulbs for Consumers is a resource for finding and comparing Energy Star qualified lamps.
