Club Lumas — Lumas Libertine — is a Swedish sex-positive club describing itself as a meeting place for mingling, BDSM, play and sex-positive people. It runs two things: a weekly Wednesday club at its own clubhouse in Spånga, going since March 2024, and a series of masked balls under the name The Lumas Society.

The Wednesday club calls itself a hybrid club and works by adapting: the room is opened up or closed down week by week to suit how many have registered and which kind of play the evening is built around. It is for over-18s and states its principles plainly — no shaming of any kind, and an aim to be one of the safest places to practise kink, whether that means play, BDSM, rope or sex. Inclusive of every gender expression and orientation, and the dress brief is come dressed, dressed up or undressed.

The balls are the other half. They run at manors and country estates outside the city as well as at the clubhouse, built around masks and anonymity — a masquerade in Södermanland, a bunny party, an autumn weekend ball in Östergötland and a glow party in Stockholm.

Memberships were abolished across all Lumas clubs in 2026. Attendance now requires a well-verified profile on the scene network the club uses, or prior approval.
