Install rope lights in two rows / Install two rows of rope lights
Remove chandeliers from the Dining room / Removal of chandeliers in Dining room / Removal of chandeliers from Dining room
Install rope lights in two rows / Install two rows of rope lights. Both of these are ok, I prefer the second.
Remove the chandeliers from the Dining room. As an instruction to do something, this is correct.
The other two with "removal" would be appropriate when referring back to the work done in an invoice; for example: "For removal of chandeliers in the dining room; Rs. 2000/-."
