Cirrus LED Grow Lights is a U.S. horticultural lighting brand developed by Cirrus Systems in Portsmouth, New Hampshire. The line launched in 2016 and focused on spectrum‑tunable, app‑controlled fixtures for indoor cultivation. Flagship Titan models (Titan 3/Titan 5) used Cirrus’s MCOB arrays and offered Wi‑Fi scheduling and spectrum control via the Cirrus Leaf app for iOS and Android. Products targeted serious home and commercial growers with full‑spectrum outputs including UV and IR and UL listing. Cirrus Systems, founded in 2012, designs and assembles LED hardware domestically; its core business is digital signage, but the grow‑light brand remains referenced by retailers and directories for its advanced cannabis‑oriented fixtures. The brand was marketed through major hydroponics retailers and cannabis platforms such as Leafly.
