History

Tideland Signal was founded by several salesmen of Automatic Power, a battery manufacturer which was then a primary player in the buoy market. The company originally sold directly to Automatic's market, but with limited success.
During the 1960s, solar cells had started to become practical systems for recharging batteries in remote locations. Hoffman Electronics, a pioneer in solar power, had approached Automatic with the idea of placing panels on their buoys to reduce the number of battery replacements needed to keep a site operations. Automatic instead saw this as a serious threat to their business, so they purchased the Hoffman concept and buried it.
Shortly thereafter, a research division of Exxon was in the process of introducing their own solar panels. Examining the market, they saw that Tideland was struggling with 30% market share, and approached them. Tideland took up development, introducing a buoy with rechargeable batteries and a solar panel. It was an immediate success, and the company soon eclipsed Automatic. By the late 1970s the solar-powered buoy was widely used.
In 1965 Tideland introduced the world first transistorized automatic lamp changer. In 1967 Tideland introduced a acrylic Fresnel lens lantern, the ML-300, which is still widely used.

Tideland ML-300

The Tideland ML-300 is a multi-purpose marine lantern, with a focal length of. It consists of a single piece injection molding acrylic 300mm Fresnel lens and a base assembly, where a flasher or lamp changer can be installed.

Since its introduction in 1967, The ML-300 is in wide use all around the world. It is in wide use in the Great Lakes region as a medium-range lens. It is also in use in Australia by the Australian Maritime Safety Authority, for example in Dent Island Light and Bugatti Reef Light, both in Queensland.
