People often associate places with particular sounds, smells and colours.
Street lighting can be part of that memory.
Someone who spent their childhood walking home under orange lamps may associate that light with winter evenings, school nights, old neighbourhoods or family homes.
Years later, seeing a photograph illuminated by the same colour can immediately evoke those memories.
The nostalgia is therefore not necessarily about the technology itself.
Few people would seriously argue that older sodium lamps were technologically superior in every respect.
Instead, people may be remembering the environment that existed when those lamps were common.
That distinction matters.
The same thing has happened with many older technologies. People can miss the look and feel of analogue televisions, film cameras, old petrol stations or traditional shop signs without believing that the underlying technology was objectively more efficient.
Street lights can produce the same effect.
The orange glow becomes a visual symbol of a particular era.
Colour rendering is where LEDs have a major advantage
One of the clearest technical differences is colour rendering.
A modern white LED can make it much easier to distinguish colours than traditional low-pressure sodium lighting.
That can matter in an urban environment.
Road signs, vehicles, clothing, road markings, building materials and other objects can be easier to distinguish when their colours are represented more accurately.
The U.S. Department of Energy has documented that replacing high-pressure sodium street lighting with LED systems can improve colour rendering alongside energy efficiency, maintenance and light-control benefits.
This is one reason the argument that sodium lighting was simply "better" becomes difficult to sustain from a technical perspective.
Sodium lamps produced a distinctive atmosphere, but atmosphere and colour accuracy are not the same thing.
A warm orange street may look beautiful while simultaneously making it harder to identify the true colour of an object.
LEDs can offer both warmer appearance and better colour rendering, depending on the specific system chosen.
The problem was never really "LED versus orange"
This is perhaps the most important point.
The choice does not have to be between a cold white LED and a nostalgic sodium lamp.
Modern LED technology has become flexible enough to offer warmer alternatives.
Local authorities have increasingly started paying attention to this issue.
Dorset Council is a particularly interesting example.
Its 2025 street-lighting policy introduced lower correlated colour temperatures for new and replacement LED lighting, with a typical limit of 2700K. The policy was designed to consider energy efficiency alongside environmental, ecological and dark-sky concerns.
That represents a significant shift in thinking.
Rather than simply replacing an old orange lamp with the brightest available white LED, councils can consider where warmer lighting may be more appropriate.
Dorset's own analysis illustrates the trade-off.
Its review found that 4000K LEDs were around 60 percent more efficient than the old sodium lighting in the council's comparison, while 2700K LEDs were still around 52 percent more efficient.
In other words, choosing warmer light does not necessarily mean returning to the inefficiency of the past.
There can be a middle ground.
Warm LEDs are changing the conversation
This may be the future of street lighting.
Instead of asking whether sodium or LED is better, councils can ask a more useful question:
What kind of LED lighting is appropriate for this particular location?
A busy urban road may require one approach.
A residential street may benefit from another.
A historic town centre may need lighting that respects the character of its surroundings.
A rural road or dark-sky area may have completely different requirements.
Dorset's policy explicitly considers environmental zones when determining lighting approaches and supports the use of warmer LEDs in appropriate locations.
Other councils have taken similar approaches.
Cumbria County Council, for example, replaced more than 45,000 street lights with LEDs and used luminaires designed to combine white and amber light while directing illumination toward the ground. The Local Government Association reports that the project was expected to reduce energy use by around 60 percent annually while also reducing light pollution.
This shows that the technology is evolving beyond the simple "bright white LED" image that many people associate with the first wave of replacements.
