The kind of lamps you have is kind of tough for me to work with. I'm more a shop light or panel light guy. You know what you want it to look like and your budget. There are wire shelves that lots of people use that work well, but most are incorporating the previously mentioned types of lights. Something like this wire shelf unit at Walmart
might work. The bases of your lamps would eat up half the top shelf space though and it would be difficult to bend them close enough to hover over the center of the shelf. You *might* could rig something up where the lamps posts (that go into the bases) go inside the corner posts of the shelf unit...but that would half to be of your fabricating.
You've got to have space above your shelving to hang/fasten whatever type of light that you're using. You could always fasten an extension post to each back corner of the wire shelf unit and use clamp lamps...but then you have the weight issue. Look through the forum at what others are using. To use your existing lamps I would almost say you need a wider shelf unit than the one I linked to and their use would be limited to the top shelf. Panels or shoplights could fit on the lower shelf.
You know your budget, what you want it to look like, but hopefully the shelf above will give you some ideas. Best wishes.
