Keldan RC1 Remote Control
Long-range wireless ultrasonic remote for the XR-series compact lights
The Keldan RC1 is a wireless remote control that adjusts the brightness of your XR-series compact lights without ever taking your hands off the camera. Built on ultrasonic technology, it reaches up to 50 metres under water and controls brightness on two independent channels, each addressing an unlimited number of lights at once. Position your lights wherever the shot demands — around a corner, behind a wreck, or across the reef — and dial them up or down on demand. Each channel carries its own ID, so multiple shooters can run remotes at the same dive site without interference.
Consider the RC1 if you:
- Want to adjust lighting from a distance without swimming back to each light
- Run multi-light setups and need independent control of two brightness groups
- Shoot alongside other photographers and need interference-free channel IDs
- Place lights out of reach — around corners or behind subjects — yet keep full control

Why the RC1
Long 50 m range
Ultrasonic signalling reaches up to 50 metres under water, so you can stage lights across a wide scene and still adjust them on the fly. Out of the water the range is limited to about 1–2 metres.
Two independent channels
Control brightness individually on two channels, with each channel addressing an unlimited number of lights simultaneously. Any light can be paired to either channel using a simple pairing mode.
Interference-free at busy sites
Each channel has its own separate ID, so several controllers can operate at the same dive site without interfering with one another.
Frees you to shoot creatively
No more swimming back and forth to adjust each light. Works around corners and through walls, lets you place lights wherever you want, and saves battery life by powering down when full output isn't needed.
