Harry Triggs

Founding Director of TM Lighting

Harry Triggs is a Founding Director of TM Lighting. Following 20 years in architectural lighting and product design, he launched TM Lighting with co-founder, Andrew Molyneux in 2012.

TM Lighting is the leading specialist in art lighting. TM Lighting believes that when art is lit to its best advantage it has the power to transform, helping the observer to fall in love with the object or subject. The business helps its clients to understand the impact that great lighting can have on an individual work or an entire collection. Using its own British designed and manufactured products, it provides tailored solutions to an international client base that includes globally acclaimed artists, private and public collections, museums and historic houses along with retail and hospitality brands.

The company adheres to its unique Three Cs methodology to bring art to life: Colour Rendition (a benchmark of 95+ CRI); Colour Temperature (warmth of light to suit the environment); and Colour Consistency (using LEDs which deliver a full colour spectrum and provide consistent colour characteristics).
