Yes, good bright LED-Light over the hole bench width is great.
At my workplace I have two 36W (1200mm) fluorescent tubes in a really rugged housing at the spot, which do just the same. But when I imitated a laboratory bench at home I used two 600mm wide 20W LED-lamps instead. Now I would use just one with 1200mm, because I always switch on both of them anyway.
Under the shelf I installed a LED-strip (3,6W/m) of the same light colour to cancel out the shadow. Not that I solder under the shelf, but the shadow bothered me somehow. But that was mainly due to the drawer storage units. I couldn't see the content of the upper drawers well.
I like to have the light source out of my way. Because it is... well out of the way. If it is bright and well distributed enough I don't need some moveable light, that I must bring to the spot where I need it. And without moveable parts and out of harms way it doesn't need to be especially heavy duty.
Being distributed over a width of 1.20 Meter the light doesn't cause hard shadows while soldering. I will attach some pictures. Note, that the one demonstrating the shadows was taken on a winter evening in the basement without additional room light. Some different light source would of course smoothen the shadows further.
