Off Topic Lights, screens and electrical things

[GLP]

We're talking about the floodlights, not the big screens and the floodlights have been specially designed not to trigger photosensitive epilepsy and have never triggered it in anyone, despite the lights now being a requirement in the Premier League and being used by many clubs in Europe.

We were talking about the screens. Glad we've cleared that up.

Everybody else was talking about the lights , only you mentioned the screens

Whatever you sat through. It's wrong. The end. Moving shapes on any screens LED/Plasma be it light or simply images moving on the screen can trigger photosensitive epilepsy.

Last time I was at a match they showed goal replays? Moving images?

It's not the moving images, it's the flicker rate (hertz). On the screens and the floodlights the flicker rate is above those levels that usually trigger photosensitive epilepsy.

Is anyone else tempted to say ‘don’t have an eppy’?

Actually we were talking about City's transfer activity.

Probably a hate crime to say that these days.

I think you'll find the conversation started with regards to the screens.

Also moving images.

Nah...

Does Angus had epilepsy?

The flashing lights pre-match could trigger a fit.

 

[Walter Sobchak]

I prefer Whiteheads to Sullivans myself.

No.

800 pages on transfer inactivity was boring , but after 2 on screens/ lights , I already miss it

 

[Bergerac28]

Its a good job they don't put a sign up now that says, if you feel ill contact a steward. They wouldn't be enough stewards to handle the rush.

 

[GLP]

Nah...

The screens can and do.

 

[Newland Tiger]

The screens can and do.

You've got a thread to talk about it now

 

[DJBlackandamberarmy(No4)]

Has anybody got a battery for an Erickson?

Fantastic.

 

[Cortez91]

Really wish I never asked now.

 

[Des Head]

Nope. Flicker rate or in some cases, specific patterns. Most of the lights you see nowadays are flickering faster than you can perceive. This boring video will show you how screens set it off.

My sister developed photosensitive epilepsy during her first pregnancy. It was triggered when she travelled beneath some trees with the sun above them. The speed she was travelling and the density of the branches created the (im)perfect flicker rate.
