Those office lights are better than the no light winters I have in Pa. I saw so many plants on the assistants shelf in their cubical that lived for years.
I will add to the what others have listed.
Euphorbia milii – Crown of Thorns. One lady in our office had one that grew so big we teased her that she was growing a weapon to use against her boss. She finally had to take it home because it got so big it was taking over her area. Plus it bloomed all year.
There were a lot of African Violets on desk. This is one plant I could never keep alive but they seem to be able to grow them beautifully on their desks. Small and flowers and very happy office plant with only office lighting.
Since you said you want to brighten up the office do not over look the pot it can make the plant special and add to brightening up the area.
