At William Artists, we’ve been pioneering architectural lighting solutions across Asia for over 40 years, partnering with global leaders like ERCO to deliver innovative, human-centered designs. As the trusted distributor for ERCO in Hong Kong, Macau, Mainland China, and Taiwan, today, we’re diving into one of ERCO’s key philosophies: the focus on effectiveness in LED lighting. This approach goes beyond mere energy savings—it’s about using light intelligently to create sustainable, impactful spaces that enhance human experiences. Drawing from ERCO’s insights on effective LED lighting, let’s explore how this principle is shaping the future of architectural illumination.

Understanding Effectiveness in Lighting: Beyond Efficiency

In the world of lighting design, terms like “efficiency” and “effectiveness” are often used, but they represent distinct concepts that are crucial for sustainable projects. Efficiency, typically measured in lumens per watt (lm/W), refers to how well a luminaire converts electricity into light. It’s a vital metric for reducing energy consumption, and ERCO excels here by incorporating top-tier LEDs and in-house developed operating electronics that minimize power use.

However, ERCO emphasizes that true sustainability comes from effectiveness—ensuring light is directed precisely where it’s needed, without waste. This is quantified in lux per watt (lx/W), which measures how much illuminance reaches the target surface relative to the energy input. By focusing on precision, ERCO’s luminaires avoid spilling light into unnecessary areas, making them ideal for zonal lighting concepts that align with human perception and needs.

ERCO’s proprietary lens-based optical systems: No Spill Light, No Wasted Light

ERCO’s proprietary lens-based optical systems are designed to project light with pinpoint accuracy, ensuring no spill light, no wasted light. Unlike traditional reflector-based technologies, which can scatter light and waste up to 60% of energy, ERCO’s lenses direct illumination precisely onto the target surface. This precision reduces unnecessary energy consumption, making electric lighting a responsible supplement to natural daylight.

For example, in applications like wallwashing or accent lighting, ERCO’s luminaires deliver high illuminance with minimal power, creating impactful designs that support both aesthetics and eco-conscious goals. This commitment to eliminating light waste is a game-changer for sustainable architecture.

Effectiveness Matters: 50% more light on the target surface

ERCO’s focus on effectiveness empowers architects and designers to create spaces that are both functional and sustainable. By delivering 50% more light on the target surface, projects achieve greater visual impact with lower energy costs. The principle of no spill light, no wasted light ensures resources are used responsibly, supporting long-term sustainability and aligning with William Artists’ mission to craft spaces that inspire connection and endure for generations.

From cultural landmarks like the M+ Museum to commercial hubs, our collaboration with ERCO brings these principles to life across Greater China. Our all-rounded services—consultation, procurement, installation, and bespoke fabrication—ensure seamless integration of ERCO’s technology into your vision.
