DW Windsor work with the City of London in colour temperature trial

May 2019, by Gemma Snelling, Marketing Manager

We know that LEDs are an advanced, energy efficient light source with many benefits – we also know that the industry is still learning about this relatively new and evolving technology and that there has been much press on blue light hazard and the possible effects on our health, particularly with regards to higher colour temperatures.

More on if LEDs are really harmful to our health here >

We are therefore encouraged to see an increase in the specification of lower colour temperatures – 3000K and 2700K - where people are the primary driver.

Last year (2018) the City of London embarked on a LED replacement programme. Their objective was to provide the lighting the City needs while improving the quality of life for workers and residents: avoiding unnecessary light pollution, over-lighting, excessive glare and inconsistencies in lighting design.

In response to the calls for lower colour temperatures, the City of London initiated a trial of 3000K and 2700K Kirium Pro lanterns at Finsbury Circus in the heart of London. 

Their impressive new lighting strategy employs the use of LED streetlights in a mix of colour temperatures, mounting heights and positions to ensure the right light, in the right place, at the right time.

The trial which started in October 2018, will run for 9 months. At the end of the period, the City will canvass stakeholder opinion on the preferred colour temperature and then convert/replace all the luminaires around the circus to the chosen option.

Andy Rogers, Mechanical & Electrical Manager, Department of the Built Environment, City of London, comments:

Both colour temperatures are much warmer than the 4000K which has been installed on the Major Routes in the City, this will help enhance the character of this distinct area. The 2700k installation is proving favourable with those who have attended the lighting trials. It will be really interesting to see which way public opinion goes.
