What Ledistys does

Ledistys Oy is a Finnish LED luminaire manufacturer founded in 2011 by three Karsikas brothers, headquartered and producing in Kempele, Finland. The company originally resold imported Chinese LED luminaires before pivoting in 2015 to in-house design and manufacturing in response to quality issues, and now offers two proprietary product families — Moduled (modular luminaires for industry, agriculture and warehouses) and Profiled (linear luminaires for sports arenas, halls, offices and commercial spaces) — plus a Lainled accessory line and the proprietary SMART lighting control system supporting DALI. Technical specifications include IP65 rating, -40 °C to +50 °C operating temperature, L90F10 > 100,000 h lifetime, up to 137 lm/W luminous efficacy, and a patented LED module overheat protection feature addressing fire safety in demanding environments such as agricultural barns.

The business model is a product-plus-service B2B offering sold almost exclusively through a direct, regionally segmented Finnish field-sales team (seven regional sales managers across Finland, plus a Sweden Sales Director) and supported by an inside-sales/contact-form/WhatsApp motion and a network of electrical and construction contractors. Pricing is project-based, quote-driven and turnkey ("avaimet käteen"), bundling free lighting audit, custom design, in-house manufacture, installation, training, and 5-year warranty (2 years in piggeries), with leasing offered for sports-hall upgrades. Revenue streams mix one-time hardware sales, professional services, and after-sales warranty support; no public price list exists and no e-commerce channel is operated. Customers span industrial (Halikko Steel, Hongisto Oy, Pyhäsalmen Metallityö), agricultural (Kinnusen navetta dairy), sports/municipal (Raahen, Pyhäjoen and Kalajoen ice arenas) and commercial segments, distributed across Finland with an emerging sales presence in Sweden.

The company is privately held and founder/family-controlled (CEO Ossi Karsikas; Atte Karsikas is a regional sales manager), with Katriina Pitkänen as Production and Finance Director and Jussi Niinikoski as Technical Director and Project Manager. It has received one disclosed funding round of approximately $765,928 from Innovestor in November 2017, displays an Avainlippu (Key Flag), CleanTech, ISO 9001, STUL warranty, and Luotettava kumppani certifications, and lists Helvar, Philips and Wago as technology partners. Revenue, headcount, and cap-table details are not publicly disclosed beyond the 11–50 employee range.

Core offering

Ledistys Oy designs, manufactures and sells modular LED luminaire families (Moduled, Profiled, Lainled) for industry, agriculture, sports halls, warehouses and commercial spaces in Finland and Sweden. The portfolio is complemented by a proprietary SMART lighting control system with DALI compatibility, and delivered as a turnkey package including free lighting audit, custom design, in-house manufacturing, installation, training and after-sales service.

Product overview

Ledistys Oy is a Finnish LED lighting manufacturer whose offering is a product-plus-service package built around three core in-house luminaire families — Moduled, Profiled, and Lainled — supported by a proprietary SMART lighting control system and a DALI option. The product portfolio is rounded out by a luminaire-mounting accessory line (Kiinnikkeet valaisimiin), a free on-site lighting survey service, a profitability/payback analysis tool, and a turnkey installation and after-sales service. Moduled is the modular, IP65-rated workhorse for industry, agriculture, and warehouses; Profiled is the cost-effective linear range for halls, sports arenas, offices, and commercial spaces; and Lainled completes the luminaire line-up. The SMART control system is the add-on module that ties them together, enabling sensor- and clock-based dimming, presence detection, and group control across both Moduled and Profiled installations. All luminaires carry the Avainlippu (Key Flag) mark and are designed, manufactured, and tested at Ledistys's facility in Kempele, Finland.
