Our light modifications were developed from cave and deep wreck diving. They were developed from a need that light manufacturers were not fulfilling. Due to the harsh environments of both cave and deep wreck exploration a more robust, brighter, and longer running light was required. All new development is tested in the same harsh environment. Our lights are tested and used below 160m (525f) depth, tight, long, and silty cave and wreck exploration. Divers all around the world are using our light upgrades with unparalleled performance and reliability. If you are ready for a serious light to keep up with your serious diving contact us.
