I think the bulbs are for sale- it may be up to the individual artists. Mine is, though it might be fun to just install it somewhere for awhile.
This was the vision of the curator (Gerardo Castro) when he came up with the project:
"Public art plays two roles in a community: It helps to create an authentic sense of place and serves as a tool for revitalization. The higher people rate the beauty of their community, the higher their overall level of community satisfaction. Human beings crave physical beauty. We look for it in so many of the things that surround us, and especially in the communities and places we live. The Lightbulb Project is consistent with the vitality and soul of the community."
