We recently talked about the City’s addition of an amber filter to LEDs and the impact it had on glare, color temperature, the reduction of damaging blue light, and the impact the filter has on luminosity in our blog post, Taking The City’s Color Temperature.
Nathan Dupre took a look at a few different filter options in this video, measuring color temperature (CCT) and luminosity as well as recording their color spectrum to see how they impact blue light. He compared two yellow and one amber filter provided by CW Energy Solutions and one light amber filter the City has been experimenting with.
