Any idea as to the lumens / watts output of typically used fittings for streetlamps Colin? (there are a lot of different designs) does the local authority just stick to one style & power output?

[Colin Deng]

It seems that on the right sight is smaller lumens than the left side, the left side install this year, while the other for over 10 years
Not sure the watts output of the lights, it do not show , or shows on the lights up there
Different city has different design of the street lights in China

Thanks Colin, it would be good to know which is the best performing for lifespan & output, as whilst we have led installed local council lamp posts I would hope solar would be coming soon on motorways & other "clear sight" locations.

I will have to do some research.
