Even more informtion on LED streetlights.
What does a regular streetlight look like?
Here's a cobrahead, they come in a variety of styles/variations.
Why should I care about this?
You should care because this will directly affect you. Specifically, if a streetlight is near your house, then changes made to it can directly affect you by the light shining in, or glare when you're walking down the streets.
I'll take action later.
Stop procrastinating! There isn't much time left, so get started now, or very soon, as many fixtures have already been swapped out.
You can also start by getting a non-LED yardlight and by telling other people about it.
I want some scientific studies!
I can see why you want them. It's hard to trust a website without them, so here are some hand-picked scientific articles that show this situation in more detail.
Reduced effect of glare disability on
driving performance in patients with blue light–filtering intraocular lenses
This study shows how lower blue light can increase the safety margin when making turns when driving. At first, you may be wondering how this study fits in with my website. But if you think
about it, the people are experiencing lower blue light levels (because there are filters in their eyes) and this positive effect can be replicated with light sources with lower blue light levels.
Should vision influence roadway lighting design?
This article compares photopic and scotopic light levels. What I can see from this study is that even though LED works well in low-light situations, it
may be a little too good at this. I have a theory why: when a yardlight or streetlight is shining into your window, you want that light to be non-disturbing. But if your vision
is scotopic, you can see details easier than if it were high-pressure-sodium (HPS). This ultimately means you're kept up at night, because all the details in your sleeping location are now visible
thus exciting your mind.
What about yardlights?
A lot of the info here applies to those too, such as not converting them to LED.
You can go to this page for that info, and then go here for a guide on yardlight maintenance.
