The lamp was made in a separate scene so that we can differentiate between them without getting confused. It also helped because we had to use different image planes and that would mean having to mess around with layouts over and over again on the same scene.
The crate is done differently. Because most of the planks are the same size, I am going to wait until i get to UV Mapping, map the small amount of planks i have at the moment and then duplicate them to get multiple crates. This is also the case with the lamp, I am going to put the final lamp into the scene when i start to UV Map the whole thing.
