In The Sims, outdoor lights come on at 6:00 pm and turn off at 3:00 am. In The Sims 3 and The Sims 4, lights are divided into five tabs in buy mode under the following titles: Table Lamps, Floor Lamps, Wall Lamps, Ceiling Lamps, and Outdoor Lights. As in The Sims, 'Hanging Lamps' is the label used for ceiling lamps. For the most part, the 'Miscellaneous' category contains street lighting. In The Sims 2, lights are divided into these categories: Table Lamps, Floor Lamps, Wall Lamps, Hanging Lamps, Outdoor Lamps, and Miscellaneous. There is also an 'Other' category, which mostly consists of outdoor lights.
When Hot Date introduced sub-categories into buy mode, floor lamps were labeled 'Standing Lamps' and ceiling lamps were labeled 'Hanging Lamps'.
Ceiling lamps were introduced in Hot Date. Wall lights were introduced with the downloadable Wall Light Pack, which was included in Livin' Large. When The Sims was first released, there were only floor lamps and table lamps.
