"I've taken my measuring gear out on the main road near us. Under the old lighting, you could see many metres into the dark parkland to the side of the road, with the new lighting, it's under 2 metres. Shocking."
That is no test at all
That is likely to simply down to the fact the lighting is more directional and have bugger all to do with the light colour? Otherwise your LED headlights would be utterly useless if the effective range is 2m
