SAMSARA floor lamps have a high color rendering index (CRI>90): their light is as close to natural as possible and naturally conveys the colors of objects. Due to its compact shape, the floor lamp does not take up much space and does not overload the interior. The base with a weight ensures the stability of the lamp.
The wide beam angle allows for uniform light dispersion. With low power, the lamp generates a high luminous flux, and you get bright lighting without excessive energy costs.
