The Ember is a putt and approach disc listed here at 3/4/0/2, while Lightspeed Disc Golf's current listings print a glide of 3; the rating listed here matches the brand's 2024 figures. Zero turn with a fade rating of 2 suggests a stable putting flight with a moderate left finish for a right-hand backhand. Its ratings suggest it is less suited to players seeking a straight putter with little fade. Lightspeed listed it as the Cosmos in May 2024 and described the Ember as renamed from the Cosmos in July 2024; the PDGA approved it as the Ember on 8 July 2024 (24-117). The brand now describes it as stable to overstable. Lightspeed says it designs, tests and produces its discs in Arizona. TryDiscs does not yet record a plastic row for it as of September 2026.
