"Who made the first LED streetlight?"Ok, well this will be a difficult answer, as probably the first LED streetlight was made in the USA or Canada. As for England, and maybe rest of the UK, our first LED lantern was the
WRTL Stela, which was made around 2008-2009. Possibly the 2nd LED lantern in UK was the
Advanced LEDs Marlin 1000, which was made right at the start of 2010. And possibly the 3rd LED lantern in the UK which was made was our
Philips Speedstar, which was made around 2011.
For the experts, please correct me If my info was incorrect. But I can be 100 percent sure the WRTL Stela was first made in the UK.
However, I have no clue who could make the first LED streetlight, but I believe it was made in the USA or Canada for sure...
