What is the best solution for replacing existing lights in order to improve the lighting efficiency of a highway?

Using the following ways,
Thanks.

Always sodium vapour lamp with yellow light (2700k),bcoz wave length is more near to natural sunlight , assumption of distance of objects for diriver will be correct which will prevent risk of accidents . Contrary to this LED has a high glaiir which irritates to drivers. You can study from the point of view safe driving the only solution which I suggested. Power saving is a different issue of LED , life saving is most important than it.

I would say that:
First, design lighting systems, to only shed light where it is required., instead of lighting up the night sky, and hide from our view, beautiful planets and stars. This can be done using well designed refractors. Two: Use devices that convert the maximum % of energy IN VS light OUT. LED is currentlly way ahead of any other technology available, at above 90% efficiency. Simple. Go for it !

Hi,
nikeetasharma
I dont know if it is best solution or not, but if we can replace existing lights with transparent concrete and solar panels on the highways. Thus, it can improve little bit lightning efficiency of a highway.

Hi, . . . There are two issues. . . One is light source efficiency from the electricity, so LED’s cover that. . . The other issue, is where the light goes . . . Many old light fittings, put a lot of light up into the night sky, wasted and causes problems. . . Much of the rest goes out sideways and again, mainly not useful. . . Modern LED fitting’s are much better at this, but the fittings are still not designed properly. . . Ideally, they should provide even lighting from right under the light, way out sideways for a specific distance, then reduce, where the next light down the road overlaps, and maintains an overall even illumination. . . Present LED’s tend to be bright under them and poor sideways light distribution.

The best solution is a combination of two approaches :

Light emitting concrete can be used as a pavement material which absorbs sunlight during day time and emit light during night.
