I chose to use an omni light for the bulb of the lamp as to have a more realistic lighting for how the light bulb works. The skylight helped make sure that everything is decently visible, and the target light help to establish a shadow on the table from the lamp. This was used with the standard light color, white, which could also be achieve by mixing Red, Green, and Blue light together. Another note is how the lighting setup doesn't have the light come through the top as the light hasn't hit anything; however, should at least allow you to see the inside of the lamp shade a bit
Summary:
There are many light concepts that can be used
Effort is needed to make lighting more realistic
