Warm White

Warm White

Warm White is a similar to conventional lighting and has a softer feel. Perfect for areas such as living rooms and bedrooms.



Daylight colour is used to represent 'daylight' indoors. It has neither the softness of warm white or the starkness of cool white.

Cool White

Cool White

Cool White is a brighter, whiter light. More suited for the bathroom and kitchen.
