Step 7: Screw in the lightbulb - Complete.

21) Screw in the energy-efficient light bulb and clip on the lid of the container. The light box is now ready to use.

I used this type of bulb for several reasons.
Firstly, the original student lamp had a wattage rating of only 20W. Putting in a light bulb that exceeds this, risks the wires, switch and connections overheating and causing fire or an electrical shock.
Secondly, energy-efficient bulbs run cooler and last longer, making this much more comfortable for my fiancée to use in her lap.
