My home bar (see photograph below) has an above eye-level shelf for hanging glasses, but this makes storing other items on this shelf area dangerous as an uneven surface is created by the inverted glasses. Further, any overhead lighting in this area (such as a small fluorescent tube) is blocked and does not illuminate the work surface below.
A small 'shelf' that sits over this area would solve the problem of the uneven surface, but not the lighting difficulty. A seperate project resulted in strip lighting to illuminate my electronics workbench. By utilising the same circuit and using high power white LED's, 'downlights' could be installed in this 'shelf' to provide the desired lighting.
Such 'downlights' from LED's would be economical to operate, easily 'concealed' in the shelving thus being un-obtrusive, and utilising the hanging glasses as 'lenses' also create a pleasing 'ambience'.
