Heliospectra is a Swedish company that makes smart LED lighting systems for indoor farming and greenhouse growing. Its main products are programmable grow lights that can be controlled by software to mimic sunlight and help plants grow faster. The company sells to commercial greenhouse operators, research institutions, and cannabis cultivators.

Heliospectra earns revenue by selling its lighting hardware and related software or control systems to customers, primarily in Europe and North America. The company is very small, with a market cap near zero, and it has struggled significantly to turn a profit — its gross and operating margins are deeply negative, meaning it costs more to make and sell its products than it earns. The key risk is whether the company can scale up sales fast enough to cover its costs, as the indoor farming industry has faced broad financial pressure in recent years, with many players cutting spending on new equipment.
