For over three decades Sessak has imported lamps designed with care from By Rydéns. Swedish design at its best, the product range of lamps from By Rydéns is a sure selection for finding the à jour choice.


Glow, clarity or mood lighting? The Dutch product family Calex has it all when looking for light sources, were it filament, LED, halogen or energy saving lamps.

Calex’s dynamic product development certifies a flow of new interesting light sources, produced with environmental and ethical sustainability in mind. Our well-equipped inventory enables off-the-shelf delivery of the Calex products.

We love good design

Promoting Finnish design is important to us. We co-operate with creative designers to bring novel, inspiring lighting solutions to the market.

Among our new products we proudly present Laaka, an ethereal, timeless piece designed by Laura Väre, and the ceramic Selma, designed by Juho Pasila and hand-made in Finland. Our designs by Matti Syrjälä, Kasper Nyman and Jenni Inkeroinen successfully light both public and private spaces.

By combining Scandinavian shapes with bold material choices and naturalistic impressions Sessak produces Finnish design to illuminate both night, and day.
