Those are a custom versions of the table lamps that players can get for The Sims 4, when they register different The Sims 3 Addons:
- Let There Be Plumbobs Award (The Sims 3 Base Game)
- Never Ending Reward (The Sims 3 World Adventures)
- Shine On Reward (The Sims 3 Ambitions
- UV Lights Reward (The Sims 3 Late Night)
- Beacon Of Ages Reward (The Sims 3 Generations)
- Paws Anonymous Reward (The Sims 3 Pets)
- Your Name In Lights Reward (The Sims 3 Showtime)
- Enchanted Aurora Reward (The Sims 3 Supernatural)
- Whatever The Weather Reward (The Sims 3 Seasons)
- Alma Mater Reward (The Sims 3University Life)
- Tiki Topper Reward (The Sims 3 Island Paradise)
- Time Travelers Reward (The Sims 3 Into The Future)
Since there's no way to unlock the items, like with the rewards from recent live events, I've set it up so that if you put down a lot that contains an original item but missing it, the game replaces it with my own custom one as a fallback object.
TOU: Do as you please! Just credit me and don't make money off of it without letting me know!
