If it is time to get rid of the 1960's era light fixture, consider recessed lighting.
Recessed lights add an elegant touch to any room and are easy to install.
There are many different kinds, some that use small flood bulbs and others that use low-voltage halogen bulbs. A trip to a lighting store is in order for the best selection. In addition, recessed lights focus the light in a smaller area so you may need more lights than were originally present. Also, please note that insulation should not be place on top of the fixture unless it is rated for such. Check the package or consult with the salesperson at the store.
