BR Series.
Engineered below
the waterline.
Surface-mounted underwater lighting with marine bronze or 316L stainless steel housing. Explore STEIN engineering for the world beneath your yacht.
Marine underwater lighting
Designed to sit below the surface.
A schematic view of stern mounting, underwater light distribution and the hull connection.
*BR 6-40 beam: 30° × 60°. Horizontal/vertical orientation shown schematically. Confirm optical orientation and final installation with STEIN for your hull.
Adaptive power control
Continuous thermal monitoring adjusts current as temperature rises. Adaptive regulation also reduces current under extended-voltage conditions.
Designed for marine supply
20–30 V DC nominal input, temporary tolerance up to 80 V DC and protection against short-duration spikes up to 200 V.
Built-in driver
A fully integrated driver simplifies the installation. The BR 6-40 datasheet specifies EMI-free operation and electronic reverse-polarity protection.

A sealed connection to the hull.
Apply marine-grade sealant to the rear contact surface before mounting. Secure with stainless steel screws and tighten evenly for uniform compression and watertight sealing. Do not coat the luminaire: the datasheet states that coating voids the warranty.
