…I think I’m having a moment here!
When LEDs became the major light source in a lighting design, I tended to add a filter to the colour and make it more like the old GLS warm white we all grew up with…to the technical that is 2700Kelvin. In the past say 5 years I moved towards a little more blue and slightly cooler light, I felt this was more modern and I liked the light with the cooler and grey pallet of colours people were choosing, so my standard colour in a design would be 3000K. What I didn’t like too much was mixing temperature of a colour in the same room, let alone building.
In 2018, I find myself moving the designs back to 2700K a tone warmer again, and I am also playing with dynamic temperature changes in the same room
…I think I am turning!
The biggest difference was that in 2012 to achieve extra warm light, we added a filter, this then tends to reduce some of the other spectrum of light and takes little edge from the performance. Now manufacturers of LEDs such as Bridgelux are making LED chips that are both warm in tone and with better colour rendering so we don’t need to add filters.
