Tideland Signal, sometimes referred to as Tidelands,[2] was a privately held, Houston, Texas based manufacturer of marine navigational aids, with main offices in Lafayette, Louisiana, Vancouver, British Columbia, Canada, Burgess Hill, UK, Dubai, United Arab Emirates and Singapore.

Tideland Signal was founded by several salesmen of Automatic Power, a battery manufacturer which was then a primary player in the buoy market.

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.

The European Commission then changed the description of one of its requirements and returned the tender documents, unopened, to the companies who had submitted them.

[11] In September 2020, Orga Signal, a Netherlands-based provider of marine navigational aids, announced that it had bought some of Tideland's intellectual property and product design assets.

[13] The Tideland ML-300 (ML for MaxLumina) is a multi-purpose marine lantern, with a focal length of 300 millimetres (12 in).

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.
