Book excerpt: Lighting has undergone a revolution in recent years, with new tools and technologies at our disposal: never before have there been so many options to achieve the transformative effects of light. Yet all too often, lighting – which does not just enable functionality, but also mood, aesthetics and flow – is misunderstood, or plain badly done. With so many options available, it’s also all too easy to make mistakes; and with new technologies such as LEDs lasting a long time, these mistakes can be expensive. Offering practical insight and visual inspiration on successful lighting solutions and schemes, this is the most accessible lighting design guide, offering a toolbox of techniques to apply in practice. Written by one of the UK's leading lighting designers on both commercial and residential projects, it features a variety of real-world projects – large and small, old and new, interior and exterior, UK and global.
