I installed a six ft. section of "warm" white LED tape just beneath my shack's tabletop riser.  It casts bright, consistent downward lighting across the entire desktop.   I use a dedicated 2-amp regulated power supply, generically sold as "MW122A."  Price is about USD $25.  It's modified with a small rheostat that functions as a non-RFI light dimmer.  One could also use an output from a fused RigRunner power manifold and still use a rheostat to control light level.
