The way I would approach the issue would be to figure out how much light is currently being produced (in terms of lumens) and if more light is needed.

Next would be the style followed by cost considerations.

Suspended tube lighting, a number of small retrofit cans (4"), cove or perimeter lighting could be considered.

New here. I was looking at Phillips Lighting USA last night for a home office. Check out the Dramalux for a more modern track. Good luck.

What's the state of development for LED track lights? I've light the Cree CR6/HD Ecosmart 575 LED can lights in my kitchen. I have an old halogen track light that goes down the bedroom hallway both for general illumination and to highlight some artwork along the hallway walls.
