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 neutral. 

However, different manufacturers have different ideas about how many Kelvin a lightbulb in their range should be, so you can’t go by the labels themselves. For example, one manufacturer may offer cool white lights that are 4,500K while another may offer cool white lights that are 6,000K, so the lighting effect from your LED light installation will be different from each bulb. 

As a result, LED light installation specialists recommend that you always look at the number of Kelvin on the box rather than the description and that you choose a high-quality manufacturer and stick with one brand for your lightbulbs. That way, you can reduce your carbon footprint and ensure your home is comfortably lit.

5 Questions About Eco-Friendly Lights Answered!

Image
As LED light installation specialists in Melbourne, we get plenty of questions about LED lightbulbs and eco-friendly lights for homes and businesses. Here are some of the most common questions about these lights.  1 – What Lights are Eco-Friendly?  LED lightbulbs are the most eco-friendly lights on the market. A good-quality LED not only lasts considerably longer than regular lightbulbs, but they also use far less energy to generate light and are fully recyclable, so they’re perfect for the planet and your wallet!  2 – Which is Better – LED or CFL?  Compact fluorescents, called CFLs, are more energy-efficient than traditional incandescent lights, using about 25-35% less energy. However, they are nowhere near as energy efficient as LEDs, which use 75% less energy than incandescent bulbs. They also have a far longer lifespan (around 50,000 hours or more), which means you don’t have to replace them as often ad CFLs either.  3 – Do You Need an Electrician to Install LED Lightbulbs?  In
