Lighting Design Consultancy
Based in Bali, Working Across Indonesia
Castellin word comes from the founder's last name, Castellini, which represents the harmony between the castle—a symbol of structure, foundation, and architectural character—and the line—a representation of light, precision, and direction.
As a lighting design consultant, Castellin views light not simply as a visual element, but as a language that shapes space. Light is the line that connects architecture, materials, and emotions, creating a spatial experience with identity.
This reflects the essence of the Castellin philosophy. We are a lighting designs that support architects, interior designers, & artists/landscape designers to show the best side of their creations.
"Where creativity and illumination become one"
Problem: Workspaces feel dim, lounge areas feel too bright, restaurants lack ambience.
Solution: Needs-based lighting design — activity analysis, functional lux standards, and fixture selection aligned with spatial purpose.
Problem: Corners, corridors, and transition areas appear dark or disconnected.
Solution: Strategic fixture placement with layered lighting (ambient, accent, task) to eliminate dead spots and achieve balance.
Problem: Direct glare, unwanted reflections, and harsh shadows affecting visual comfort.
Solution: Beam angle control, optimized cut-off angles, UGR/anti-glare strategies, and deep recessed fixture recommendations.
Problem: Lights operate at full power constantly or use outdated technology.
Solution: LED efficiency upgrades, dimming systems, zoning, motion sensors, and smart control integration.
Problem: Color temperature varies between fixtures, objects and materials look dull or distorted.
Solution: Standardized CCT & high CRI specification (CRI ≥ 90), brand consistency, and calibrated product selection.
Problem: The built result does not reflect the design intention.
Solution: On-site mock-ups, continuous coordination with MEP/interior teams, and fixture point validation before ceiling closure.
Problem: Clients are pushed into expensive solutions they don’t actually need.
Solution: Curated fixture options based on value-to-performance, offering tiered alternatives for each budget scenario.
Problem: Lighting becomes an afterthought, causing compromises and rework.
Solution: Early-stage lighting budget planning, RAB breakdown, and scalable design proposals (low / mid / premium).
Problem: Hospitality, retail, and commercial spaces fail to communicate identity or storytelling.
Solution: Experience-driven lighting — ambience settings, contrast ratios, zoning, and mood composition aligned with the brand vision.
Problem: Systems underperform due to lack of guidance; fixtures fail prematurely.
Solution: Maintenance manual, staff training, as-built documentation, and optional after-service support.
