The Switch to Outdoor LED Lighting Has Completely Backfired
- jrs235 9y agoMy biggest complaint is the temperature of the LED lights. They are too white, jarring, and harsh.
- ams6110 9y agoThat's why I still use incandescents at home. CFL were inferior in terms of color temperature, LEDs are even worse
- gbuk2013 9y agoHigh CRI warm LEDs exits but you have to go looking for them (source: I have lots of them installed in my house including some very warm lights in the bedroom that are lovely and comfort-inducing, much more so than incandescent bulbs).
- pcurve 9y agocan't you add warmth by putting it behind warm glass cover? I have LED overhead room lights and they're pretty warm and yellow.

- mc32 9y agoWe need the low spectrum of high pressure sodium lamps for street lights. in all seriousness, I used to think those yellow lights were annoyingly dim, but now I think whoever chose them was right to seek these lights as they are less offensive.

- dwaltrip 9y agoThis seems to be very similar to the concepts of "induced demand" and "jevon's paradox". Essentially, these principles all seem to be saying that if something becomes significantly more accessible (whether by decreased price, increased efficiency, and/or increased supply), it's not uncommon for demand to increase in kind, as new uses become economically viable.
- dingaling 9y agoOne of the major causes of always-on street lighting are the electricity companies who offer local authorities bargain rates overnight in order to smooth usage. My local authority looked at turning-off street lights from 02:00 to 06:00 each day ( as they did before 1968 ) but calculated that the doubled cycle load on the sodium lights would lead to more failures. Given that unknown cost, versus fractions of a penny in electricity per light per night, they elected to keep the lights lit. So now we have more LED lights and always-lit.
