What is cold white light?
Definition
There are many factors to consider when buying LED lighting, namely: watts, Kelvin and lumen. In lighting terminology, the term ‘cool white’ is sometimes used. This refers to how the light appears – in other words, the light image. The higher the Kelvin rating, the cooler and whiter the light will appear. Anything above 4500 Kelvin is considered cool white. Cool white is often compared to clear daylight. The light creates an energetic and active atmosphere. This light colour is often used in places where brightness plays an important role.
What is the difference between warm white light and cold white light?
When considering LED lighting for vehicles, you often come across the terms "warm white" and "cold white". The difference between these is that the light colour of LED lighting is represented by a matching colour temperature. The higher the Kelvin value, the cooler the colour of the light. The lower the Kelvin value, the warmer the light is going to be.
| Features | Warm white light | Cold white light |
| Colour temperature | 2700 to 3500 Kelvin | 5000 to 7000 Kelvin |
| Scope | Living spaces, relaxed atmosphere | Outdoor lighting, headlights, work lights |
| Visibility | Lower, cosy atmosphere | Higher, better visibility |
| Energy efficiency | Energy-efficient but lower light output | Energy-efficient with higher light output |
| Aesthetics | Traditional, cosy | Modern, clear |
How many Kelvin does my LED light need?
When choosing the right LED lighting, you need to consider the correct colour temperature. First, you’ll need to determine the purpose of the lighting. In a commercial vehicle, for example, you’ll want as much light as possible to ensure a clear view. In this case, you’re looking for cool white light with a high Kelvin rating. Are you looking for suitable LED lighting for your vehicle but can’t quite figure it out yourself? The TRALERT® technical team is on hand 5 days a week to assist you.
