To be fair it isn't the LEDs that are the problem, it is the choice of the colour temperature. They could just as easily make them a warm white instead of the harsh blue they currently choose.


Exactly. Auckland Council have decided to go with 4000k (https://at.govt.nz/media/310324/atcop_section_19_street_lighting.pdf section 2.2) with an expected 20 year lifespan.

NZTA also prefer 4000k, but do state in (https://www.nzta.govt.nz/assets/resources/specification-and-guidelines-for-road-lighting-design/docs/m30-accepted-luminaires.pdf) that 3000k can be used.


Both Wellington and Dunedin will use 3000K ( although Wellington will use 4000K on main arterials

Street lights, don't need them on no exit side streets/non main roads. Our street doesn't have them, which is great because I hate those things shining in windows and sneaking past curtains at night - I didn't notice our street was missing street lights until our neighbour pointed it out not long after we moved here, and realised they are indeed a complete annoyance and waste of electricity. The main road does have em, recently replaced with LED, but like all street lights, too much light leaks out sideways, never understood why they don't have shades on them to direct the light down - you know, where its needed?
