Lighting Design Partnership International (LDPi) provides professional lighting design services at an international level. It provides a range of services working with architects, consultants, designers and clients, from advice on small scale projects to a full design and implementation service on large scale projects. LDPi's approach to lighting design is organic and recognizes that daylight is not static. Change in light quality is vital to people's well being and stimulates emotions. Most projects develop an integral change and control of lighting to compliment the way people perceive the changing patterns of light that surrounds people.
