Ikelite B3 Bulkhead & Hotshoe Upgrade Kit for Ikelite DL & DLM Housings
The Ikelite B3 Bulkhead & Hotshoe Upgrade Kit provides the most reliable waterproof electrical flash connection, trusted by professional underwater photographers for over 30 years. Featuring a hard anodised aluminium body with gold-plated connectors, this kit ensures durability and superior performance in underwater environments.
Upgraded 2025 Model
In 2025, Ikelite introduced a new style connector with several key improvements:
- Enhanced Flexibility: Slimmer and more flexible cabling makes routing around accessories like USB-C charging or HDMI monitor cables easier.
- Improved Durability: Flat-type connector terminations reduce the risk of accidental wire breakage.
- Compact Design: Low-profile structure provides additional clearance between the hotshoe and housing interior.
- Safety Connector: Non-locking design releases under strain to prevent wire damage.
- Auto-Switching Feature: Compatible with Canon, Nikon, Olympus, OM System, and Panasonic cameras without requiring hotshoe changes when using a TTL converter (not available for Sony cameras).
All Ikelite housings shipped from January 1, 2025 (serial number 81200 and higher) feature this new system. Older housings below serial number 81200 can be upgraded using this kit. Ensure you select the correct kit based on your camera brand and Nikon hotshoe cable orientation. Refer to the Hotshoe Reference Chart for compatibility.
Note: Clear housings and older Ikelite housings with a right-angle bulkhead on the back are not compatible with this upgrade. If your housing has non-working electronics, please contact us for upgrade options.
