I use the mini-techlite dual LED "Larry Robinson" model and have found it to be extremely helpful. My problem was also shadows that were hard to get rid of with typical swing arm lamps. The mini-techlite does take a little getting used to, but I have found it great for keeping the light focused in front of me and on the work and the magnifiers are a great help.
I use mine at my regular job as well which involves examining electronic circuit boards and was the primary reason I opted for the dual LED model. The extra illumination provided by a wider field of light has been well worth it.
My two cents worth...
PS- A note on the photo. I have modified the headband slightly on mine to allow it to pack up a little flatter when I travel. The headband is all one piece as they come from QED Lighting.
