What Kelvin does

Kelvin, operated by Kelvin Group AS and headquartered in Vinterbro, Norway with European offices in Berlin and Munich, designs and manufactures professional LED cinema and broadcast lighting fixtures built on its proprietary Cantastoria RGBACL six-color light engine (Red, Green, Blue, Amber, Cyan, Lime), which is paired with a patented mathematical mixing model and manufactured in Norway with individual calibration. The product portfolio centers on the Play Series of pocket-sized RGBACL panel lights (Play, Play Pro, Play Air, Play Hero) priced from $199 to $349, and the Epos Series of COB studio lights (Epos 300 at $1,999 and Epos 600 at $2,999), supported by a Bowens S-compatible accessory ecosystem including the Versa 10 Fresnel, softboxes, honeycomb grids, and travel kits. Key technical features include CRI 97-98, TLCI 99, 1,700K-20,000K CCT range, IP65 ingress protection on key models, built-in LumenRadio CRMX wireless DMX, Bluetooth control via the Kelvin Narrator iOS/Android app, and a Python developer interface.

The company serves cinematographers, directors of photography, gaffers, lighting technicians, photographers, videographers, and broadcast facilities, with named reference customers including Radio France, ProCam USA, Greig Fraser ASC/ACS (Project Hail Mary), Jem Schofield, and Michael Mark Lanham. Revenue is generated entirely through one-time hardware sales distributed via direct e-commerce on kelvinlight.com, a global network of authorized dealers and rental houses, and regional partners including Woosik Kim in Korea and Lux Lighting in the USA, supported by a 180-day risk-free trial, 3-year Keep Rolling Warranty, and free lifetime firmware updates.

Kelvin was founded in 2010 by LED technology company Rift Labs and gained industry recognition through consecutive NAB Product of the Year awards in 2023 (Epos 600) and 2024 (Play Pro), plus reddot, iF Gold, and DOGA design awards for the Epos 300. In September 2025, Kelvin announced a strategic partnership with SmallRig ahead of IBC 2025, and on August 28, 2026, SmallRig Technology (HK) Limited completed acquisition of selected Kelvin Group assets, including the Kelvin brand, intellectual property, and selected product portfolios, with Kelvin continuing to operate as a brand within SmallRig's portfolio.

Scale indicators3 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• ARRI: German manufacturer of professional cinema cameras and lighting (SkyPanel, Orbiter, L-Series). ARRI is the dominant incumbent in film/broadcast lighting; Kelvin's Director of Product (Florian Bloch) came from ARRI. Both serve DPs, gaffers and studios with high-end RGB/RGBW COB fixtures.
• Kino Flo Lighting Systems: Long-established American LED/fluorescent cinema lighting manufacturer (Celeb, Free Style, Diva-Lite). Kino Flo is a legacy incumbent serving the same DPs and rental houses as Kelvin, with strong color science heritage.
• Litepanels (Vitec Group): Broadcaster-oriented LED panel manufacturer (Astra, Gemini, Sola) owned by Vitec Group. Litepanels competes in the broadcast/television segment with Kelvin — particularly relevant given Kelvin's relationship with Radio France.

Direct peers

• Aputure: Direct competitor in RGB and RGBWW LED cinema lighting (LS 600 series, Nova, MT Pro). Aputure targets the same cinematographer, gaffer and content-creator segments with a much broader catalog and aggressive price-to-performance positioning — the closest head-to-head to Kelvin's Epos and Play lines.
• Godox: Chinese manufacturer offering LED panels, COB studio lights and pocket lights (KNOWLED, ML, VL series) for film, broadcast and photography. Godox competes across Kelvin's price tiers with broader distribution, particularly strong in Asia-Pacific.
• Nanlite: LED lighting manufacturer (Forza, PavoTube, MixPad series) serving cinematographers, photographers and content creators. Nanlite's Forza 500/720 and PavoTube T8 overlap directly with Kelvin's Epos COB and Play pocket lights.
• Astera: German maker of wireless LED tubes, panels and cinema lights (Titan, Hyperion, NYX). Astera targets the same professional film/broadcast and event-production segments with battery-powered, CRMX-controlled fixtures — strong direct overlap in use case and buyer.
• Rotolight: UK-based LED lighting manufacturer (Neo, Titan, AEOS) specializing in RGBWW continuous lighting for film, photography and broadcast. Rotolight directly competes with Kelvin's premium positioning and shares the same pro-photography/filmmaking buyer.

Emerging players

• Digital Sputnik: Boutique modular LED lighting system for cinema (Voyager, Modular). Smaller scale than Kelvin but addresses the same high-end cinematography customer with modular, color-accurate fixtures.
• BB&S Lighting: Compact LED lighting specialist (Force 7, Pipeline) for film, broadcast and photography. BB&S competes in the same professional niche with high-CRI, color-accurate fixtures, though at lower brand recognition than Kelvin.
