Converted a bedroom into an office and tried keeping the light fixture with two 5000k LED bulbs; the room still felt a bit dark. Found a LED Color Changing Flat Panel in Home Depot and I am extremely happy with the outcome.

The before shot is with the 5000k bulbs.

I purchased mine at a local hardware chain (Home Depot), but there is a similar item at Amazon.
