All you should know about sustainable lighting

And how to improve your interior design
A brief history of lighting in interior design:

From fire to smart LEDs

Lighting has always been more than just a way to illuminate a space—it shapes mood, enhances aesthetics, and transforms interiors. From the flickering glow of ancient torches to today’s energy-efficient smart LEDs, lighting has evolved alongside architecture and technology, reflecting cultural shifts and design trends throughout history.
In the earliest homes, fire was the only light source, with oil lamps and candles gradually introducing more controlled illumination. The grand chandeliers of the Baroque period turned lighting into a status symbol, while the invention of gas lighting in the 19th century brought a warm, ambient glow to homes and city streets. Then came the game-changer: electricity. With Thomas Edison’s light bulb in the late 19th century, interior lighting became more accessible, leading to the rise of Art Deco pendant lights, mid-century modern fixtures, and today’s sleek LED solutions.

Now, lighting is not just about function but also well-being and sustainability. Smart lighting adapts to our daily rhythms, LED strips create futuristic accents, and daylight integration enhances energy efficiency. As we continue innovating, the future of interior lighting will blend aesthetics, technology, and eco-consciousness like never before.
Want to know how to choose the best lighting for your home? Let’s dive in.
Sustainable lighting in architecture focuses on energy efficiency, environmental impact, and human well-being. Here are the 7 key things to know:

1. Energy efficiency
  • Use LED lighting, which consumes up to 80% less energy than incandescent bulbs and lasts significantly longer.
  • Opt for smart lighting systems (motion sensors, daylight harvesting, dimmers) to reduce unnecessary energy use.
  • Efficient fixture design minimizes energy waste (e.g., reflective surfaces, proper shielding).
2. Daylighting integration
  • Maximize natural light using windows, skylights, and light shelves.
  • Consider building orientation, shading devices, and high-performance glazing to control glare and heat gain.
  • Use light tubes or fiber optic daylighting to channel sunlight into interior spaces.
3. Material sustainability
  • Choose fixtures from recycled, biodegradable, or locally sourced materials (e.g., bamboo, recycled aluminum, glass).
  • Avoid toxic materials like mercury in CFLs or hazardous coatings.
4. Human-centric lighting (HCL)
  • Consider circadian lighting to mimic natural light patterns, supporting health and well-being.
  • Use warmer light temperatures (2700K-3000K) for relaxation and cooler light (4000K-5000K) for productivity.
5. Dark sky & light pollution reduction
  • Use shielded outdoor lighting to direct light downward and reduce skyglow.
  • Choose warmer-colored lights (below 3000K) to minimize disruption to ecosystems.
  • Implement adaptive controls (timers, dimmers, motion sensors) to reduce unnecessary nighttime lighting.
6. Renewable energy integration
  • Power lighting with solar panels or connect to a green energy grid.
  • Use solar-powered outdoor lights or hybrid systems to reduce reliance on fossil fuels.
7. Lifecycle & maintenance consideration
  • Choose long-life, low-maintenance lighting solutions to reduce waste.
  • Implement a circular economy approach, where fixtures are designed for disassembly, recycling, or repurposing.
Lighting in interior design

The best lighting solution for interior design balances functionality, aesthetics, energy efficiency, and human well-being. The right approach depends on the space and purpose, but here are five key principles and recommendations:

A well-designed space uses a combination of these three lighting layers:

1. Layered lighting approach

Ambient (General) Lighting- For overall illumination
  • Best solution: Recessed LED downlights, pendant lights, or cove lighting.
  • Example: Warm LED ceiling fixtures in living rooms for a cozy feel.
  • Tip: Use dimmable LEDs (2700K-3000K) to adjust brightness.
Task lighting- Focused light for specific activities
  • Best solution: Under-cabinet LEDs (kitchen), desk lamps (offices), or reading lights (bedrooms).
  • Example: Adjustable LED task lights on office desks to reduce eye strain.
  • Tip: Use cooler light (4000K-5000K) for workspaces to boost focus.
Accent lighting- For highlighting design elements
  • Best solution: Wall sconces, LED strip lights, spotlights, or picture lights.
  • Example: LED strips behind a TV or under floating shelves for a modern look.
  • Tip: Use a CRI (Color Rendering Index) of 90+ for true color representation.
2. Smart & adaptive lighting
  • Smart bulbs & dimmers (e.g., Philips Hue, Lutron Caséta) let you control brightness and color temperature.
  • Human-centric lighting mimics natural daylight cycles to support circadian rhythms.
  • Motion sensors & daylight harvesting reduce energy waste in hallways and bathrooms.
3. Best lighting by room
Living room- warm & layered lighting
  • Use dimmable LEDs with warm tones (2700K-3000K).
  • Combine chandeliers, floor lamps, and wall sconces for depth.
  • Accent artwork or architectural features with spotlights or picture lights.
Kitchen- bright & functional
  • Use bright (3500K-4000K) LEDs for task lighting.
  • Install under-cabinet LED strips for counters.
  • Consider pendant lights over islands for a stylish touch.
Bedroom- Relaxing & cozy
  • Use warm white (2700K-3000K) bedside lamps.
  • Add dimmable LED strip lights under the bed for a floating effect.
  • Avoid blue light before sleep – choose warm, indirect lighting.
Office/ study- focus-boosting
  • Use neutral or cool white (4000K-5000K) desk lamps.
  • Position lighting to reduce shadows and glare.
  • Adjustable task lighting helps reduce eye fatigue.
Bathroom- bright but soft
  • Use vanity lighting around mirrors for even illumination.
  • Soft warm white (3000K-3500K) LEDs for a spa-like feel.
  • Consider waterproof LED strips for shower areas.
4. Sustainable & aesthetic fixture choices
  • Recycled or eco-friendly materials: Bamboo, reclaimed wood, recycled glass.
  • Minimalist & Scandinavian designs: Sleek pendant lights or wall sconces with diffused light.
  • Industrial style: Exposed filament LED bulbs for a vintage look.
5. Lighting trends in interior design (2025)
  • Biophilic lighting – Incorporating natural light and organic materials.
  • Concealed LED strips – Integrated into walls, ceilings, and furniture.
  • Dynamic lighting – Color temperature shifts throughout the day.
  • Sculptural statement fixtures – Functional yet artistic lighting pieces.
For a perfect lighting solution, mix layers, use smart controls, and select fixtures that match your design style while considering energy efficiency.
