Paul Beale is the Founding Director of 18 Degrees, an architectural lighting design consultancy based in London. 

He began his career in lighting design at Arup in 1996, founded Electrolight in Australia in 2004 and established 18 Degrees upon returning to the UK in 2014. 

Paul also leads 18 Circular, an initiative that treats Cat A luminaires as leased assets rather than consumables. Through this model, luminaires are recovered and recertified for redeployment across multiple buildings. The approach has been independently validated as achieving embodied carbon reductions of up to 89% compared with conventional Cat A lighting.
