What Light Factor does

Light Factor is a privately held Bulgarian lighting design consultancy headquartered in Sofia that delivers end-to-end architectural lighting projects — concept, technical specification, photorealistic 3D visualization using real photometric data, on-site implementation, and DALI control-system scenography — for hospitality, corporate office, retail, cultural/heritage, residential, industrial, and urban/outdoor clients. Its core differentiator is a designer-led workflow that combines advanced 3D visualization (with actual beam angles and luminaire intensities rendered into models), intelligent lighting controls such as DALI for programmable scenes and adaptive circadian color-temperature schemes, and a broad specification portfolio drawn from a network of 40+ European lighting manufacturers including iGuzzini, Zumtobel, Thorn, FLOS, and BEGA. The company does not manufacture luminaires; instead it earns professional-services fees for design work and acts as the specifying and integrating party for hardware from its partner brands.

Commercially, Light Factor operates a sales-led B2B model targeting mid-to-large projects through direct engagement with property owners, developers, hotel chains, and corporate end-clients, complemented by long-term referral relationships with architects and interior designers who specify Light Factor into their projects. Pricing is project-based and not publicly disclosed; contracts are described as multi-year and scoped per engagement. Distribution is overwhelmingly domestic — projects span Sofia, Plovdiv, Borovets, St. Vlas, Burgas, and Sveshtari within Bulgaria — with occasional regional work such as the UNESCO World Heritage Thracian Tomb of Sveshtari restoration. Customer logos include Hyatt Regency, JLR and Maserati showrooms, ING Bank, Roche, Teva/Actavis, Experian, Payhawk, JYSK, the Bulgarian Academy of Sciences, and multiple hotel and residential complexes, indicating an enterprise-only, project-anchored book of business rather than SMB volume.

The company is privately held with no disclosed external funding, operates with 11–50 employees, and is led by General Manager Rossen Yovchev (Росен Йовчев) and CEO/Founder Mariana Chalakova. It co-locates with sister firm CDD under the 'light+living' showroom at 17 Sveta Gora Street in Sofia, used as a client-meeting, training, and event venue.

Direct peers

• Speirs Major: Global architectural lighting design consultancy headquartered in the UK, serving cultural, hospitality, and urban infrastructure projects. Direct peer: same business model (lighting design consultancy, no manufacturing), similar high-end project portfolio.
• Sutton Vane Associates: UK-based architectural lighting design practice. Already named as a strategic partner to Light Factor on the Thracian Tomb of Sveshtari project, making it the closest direct peer in service scope and cultural-heritage project expertise.
• The Lighting Practice: US-based independent lighting design consultancy serving commercial, hospitality, and cultural projects. Direct comparable in terms of being a non-manufacturer design firm delivering photorealistic visualizations and control-system integrations.
• Lighting Design Partnership (LDP): UK-headquartered international lighting design consultancy. Direct peer with very similar service portfolio (interior and exterior lighting design, controls integration, heritage and hospitality specializations).
• ICrave: US-based experiential and lighting design studio serving hospitality, retail, and immersive environments. Direct peer for premium hospitality and showroom (e.g., JLR, Maserati) lighting design projects.

Broad incumbents

• Arup Lighting: Lighting design practice within Arup, the global engineering consultancy. Operates a much larger, broader portfolio of building services but competes for the same high-end architectural lighting design mandates and uses the same DALI-based control expertise.
• Signify: Global lighting manufacturer (formerly Philips Lighting) and integrated services provider. Broad incumbent offering lighting products, networked controls (Interact), and increasingly bundled design services — a meaningful supply-side competitor and partner to consultancies like Light Factor.
• iGuzzini Illuminazione: Italian architectural lighting manufacturer (now part of Signify), Light Factor's primary product partner. Supplies fixtures used in flagship Light Factor projects; represents the supply-side incumbent most likely to bundle design services and compete downstream.
• Zumtobel Group: Austrian lighting manufacturer and DALI control systems originator. Supplies luminous panels and controls used by Light Factor (e.g., Maserati showroom) and competes as an integrated solutions provider in the same enterprise specification process.
• Thorn Lighting: European outdoor and street lighting manufacturer (part of Zumtobel Group). Supplies outdoor luminaires used by Light Factor (Business Park Sofia) and competes for the same facade and urban lighting specification mandates.
