Lamps Plus was founded by Dennis Swanson and his wife Manja. Originally the name of the store was Lamps R Us, but after being sued by Toys R Us, the company changed the name.
Swanson and his wife began by designing and manufacturing lights and lamps for other retailers before deciding to go into business for themselves. The company holds several patents for unique light fixtures, including one for a torchiere floor lamp with adjustable side lamps.
From their single location in Los Angeles, the company now has more than 40 locations, as well as international stores. Lamps Plus also offers an active e-Commerce site. The company website was picked as one of the top fifty retail websites by Internet Retailer magazine in 2004 and has remained in the top 200 every single year since.
The company has worked with a number of designers, including industrial pattern designer Stacy Garcia, furniture and lighting designer Sergio Orozco, lighting designer Robert Sonneman, artist Thomas Kinkade, as well as pop artist Ragnar.
Global headquarters for the company are located in Chatsworth, California, a suburb of Los Angeles. In 2017, the company opened their first location in Austin, Texas, with the stores focus being on LED lighting.
