Lose the Shade: bare bulbs

I really like the minimalism of a hanging bulb with no shade.   The design is modest and quickly presents the function of a light source.  In casual areas, there's no need for the formality of a shade, and they're practical in lighting small areas.  While the design seems rudimentary, the use of dropped lights consisting of a bare bulb and cord was an improvement in illuminating the small, dark work areas of tradesmen and thus increased their productivity.  Well I'm sold, utility and aesthetics all in one.  I think they would be great above an island in a kitchen of a loft space or clustered together above an eating area as seen below.   Some of the pictures below even use them more formally in a living area.  Instead of a traditional round light bulb, I think I would go for a vintage Edison style light bulb.
