There is nothing wrong with LED lights. There is just a big problem with cheap, poorly designed LEDs. You can use proper optics and control the light exceptionally well and put it exactly where its needed with very little spill over or reflections up. You can also chose whatever color and color rendering index (CRI) you like but all of this costs more money and municipal bean counters are drunk on the lowest bidder. So we get glare bomb blue light shows. I used to design this stuff so feel free to ask questions.
So I’m a wedding photographer and in the past 3 years I have noticed an increased amount of the lights at venues strobe or have really bad banding when I set my shutter speed to higher than 120. My assumption is that the new LED lights are flickering at a consistent rate to save energy but at the cost of the photos I take. Is this the case? That cheaper LED lights will flicker like that?
The strobing is due to the way they’re powered. When converting AC power to DC power, you can either convert the positive half of the AC sine wave (half rectified) or both positive and negative sides of the AC wave (full rectified). Cheap lights use half rectifiers so as the AC feeds in, the light is only getting powered half the time and off the other half of the time. This happens so rapidly that we don’t really see it with our eyes, but with a camera it’s very noticeable. AC cycles at 60 cycles per second (in the US), so it makes sense that you’re seeing it at 120 shutter speed as this equates to 60fps.
I’d consider talking to some of these venues about it as I assume they’re typically used for events that’ll be filmed, so using shitty lighting is ruining it for everyone same as if they had the toilets sitting in the middle of the dance floor.
Why did you use a redirection link instead of the original link?
Are you trying to track user interaction?
It’s a “gift article” to get past paywall: https://helpcenter.washingtonpost.com/hc/en-us/articles/4403823008539-How-to-use-gift-articles
it says the gift article is expired for some reason

I’ll edit the link for the post. Sorry, didn’t realize these type of gift links expire after 14 days.
thanks!
It’s just a shortened link, probably copied it for mobile.
But what’s the point of shortening it? I want to see the source before clicking on a link.
He likely wasn’t responsible for shortening it, Washington post did it automatically when sharing the article. Everything does this nowadays Google maps adds trackers to the url when sharing as well. I agree it’s annoying but not many good ways around it.
That makes sense. Thanks!
