Warm Light vs. Cool Light vs. Daylight

One of the easiest ways to reduce your carbon footprint is to choose an LED light installation for your home through the Victorian Energy Upgrades Program . Getting the right LEDs is an important part of this process – so what do the terms “cool white”, “warm light”, and “daylight” mean? Colour Temperatures for Lightbulbs Light colour temperature – the colour of the light that the bulb emits – is measured in units called Kelvin (K). The higher the number in Kelvin, the whiter and crisper the light, while lower numbers give a warmer, yellow glow. To make it simpler, LED lightbulb manufacturers give their range of bulbs different names to help describe the light they emit. Their high Kelvin bulbs will be called “cool white” because this very white light has an almost blue tone to it. The low Kelvin bulbs will generally be called “warm white” because they tend to have yellow tones. And right in the middle of the two ranges will be a “daylight”, which should be fairly ...
