Description
The Collingwood H2 Lite CSP is a premium wattage and CCT switchable residential downlight engineered as the ultimate fit-and-forget lighting solution. Designed for electricians and installers who demand flexibility without compromise, the H2 Lite CSP allows colour temperature to be selected between 2200K, 2700K, 3000K, and 4000K — simply by twisting off the bezel and flicking the front-face switch at installation. The addition of 2200K ‘Ember Light’ makes it ideal for creating warm, cosy atmospheres while minimising blue light exposure.
