LED colour

Peter Carson

The LED streetlight change over is complete in my area. I understand the LED type in the lanterns are a mixture of 5700K and 4000K. Most LED manufacturers refer to 5700K as cool white, 4000k as natural and 3000k as warm white. I wasn’t aware of the implications of blue rich light when the change over first started in my area, by the time I became educated it was too late.  Unfortunately the LED street lights have a service life of about 25 years so they will probably see me out!!
