LED on Washington Metro enrages city bigwigs

The train lighting on the Washington Metro was originally designed to match the warm hue of the stations, creating a twilight feel throughout the day. The new LED trains however, create a jarring comparison. 

Washington DC, home to the American power elite, has seen many controversies rise and fall, the latest, however, doesn’t involve presidents or congressmen, but the new LED lighting on the city’s Metro network. And it's not only commuters that are enraged, lighting designers with any sense of history are cringing at the network's tinkering with an iconic, if unusual, scheme. 

The trains on the Washington Metro, which is the third largest and third busiest transport system in the United States, have recently been upgraded to feature white-blue LED light.

Detractors of the upgrade, of which there are many, have labeled the new light as ‘clinical’ and have equated their commutes to ‘walking into a giant Xerox machine’.

The architecture of the Washington Metro and indeed the original lighting scheme is condidered to be something of a design classic by architects and lighting designers alike.

The lighting scheme was developed by the iconic lighting designer William Lam and it is widely viewed as being one of the finest examples of integrated lighting design in the world.

Working in conjunction with the Metro’s architect, Harry Weese, who developed the network in the Brutalist style, Lam created a lighting scheme that set out to be comprised of warm light, in direct juxtaposition to the hard concrete style of the stations. He also aimed to create a lighting design that prevented commuters from feeling claustrophobic.

A pioneering use of uplights were used to illuminate the architectural surfaces, which today is taken for granted, but at the time was something of a revelation.

The idea was to make transport in the city as warm, welcoming and pleasant as possible for federal government employees, a notion that was dreamed up in the age of Lyndon Johnson and the Great Society, when government was perceived as striving for the common good, a perception that wasn’t to last long.

In the years that have passed Lam’s original warm T12 fixtures have been replaced with T5s and despite the network’s attempts to make sure that the light temperature remained between the 3500K to 3000K level, the tone of the illumination has gradually been getting brighter.

The recent instillation of LED on the network’s trains has completely blown Lam’s original intentions out of the water and people aren’t happy.

The train lighting was originally designed to match the warm hue of the stations, creating a twilight feel throughout the day, meaning the new LED trains create a jarring comparison.

Reactions on social media have not been kind, with one regular commuter describing the new lighting as, ‘creating a pallid, factory-like and unwelcoming ambiance’.

Of course the new and bright-blue lighting mixture is good for the morning and will act in concert with commuter’s circadian rhythms to ensure that they are awake and ready for work. However, at night, the opposite will be true.

The disdain for the new lighting has not been unanimous though, with some saying that brighter lights will lead to a safer network.

‘Customers frequently comment about station lighting,’ Metro spokesman Dan Stessel told The Washington Post. ‘They ask us for brighter stations, which also helps them feel safer and more secure.’

It remains to be seen if the majority of Washingtonians will be won over to their ever brightening Metro network, but with further LED train conversions in the pipeline, commuters may have no choice but to adapt.

This would have been a perfect space to apply an adaptive human centric lighting system changing with the time of day.

Kind of hard to tell from the photos what's going on. The main photo seems to show a rather sickly institutional green lighting with maybe some warm daylight color temp coming from inside the cars. This maybe a photographer's problem - not correcting for color temp. The middle photo shows some violet in the ceiling with warm white in the cars and maybe some daylight ~4000 K on the walls. The third photo with a train moving through shows what appears to be a 4000 -5000 K uniformly on the ceiling and some wall areas except for the shadowing effect of the train because the light source is mounted too low to provide uniform lighting when a train is in the station. Overall it looks a though little thought was given to the impact of mixed color temps and shadowing. Strictly amateur night on the design. Should stick to one color temp unless the goal was to make some sort of artistic statement of differing colors - in which case it seems the artist's goals are not appreciated here.

When will lighting designers or those that specify lighting realize you must run consumer tests when making a major appearance change? Especially to iconic lighting systems. This is not a new concept but seems to have to be learned over and over. As for the whiter lighting in the metro impacting circadian cycles either positively or negatively, please give me a break. The science says any possible effect would need to be assessed via dose (amount), actual spectral distribution, and duration (time of exposure). I am sure this has not been performed on this system, so to speculate about its impact in this regard is nonsense.

Furthermore they did the same with all the buses in London particularly the so called Boris buses where you have an LED 6inches from your head in some places . It used to be a good experience being on a bus at night with its soft warm light which was perfectly adequate for all uses . Now this hard aggressive grey/ white is so depressing .

This does not surprise me . So many lighting designers these days ignore the psychological and physiological impact of lighting on human beings so obsessed are they with effects and maths. The original concept was perfect why change it ?
