  • Features

    Collingwood H4 Pro smart downlights with colour temperatures tuneable control. Dim, switch and adjust the colour temperature from 3000K to 6000K using your smartphone with these brand new LED downlights.

    The H4 Pro is adjustable, allowing you to redirect the angle of the light onto a given area or object. They also have a higher CRI (colour rendering index) of 95Ra which produces colours more accurately. This is quite a unique feature for integrated LED downlights and something we've been requesting for years.
