Christmas LED Lighting

[Minas Tirith]

Hello :)

When I was young, Christmas lights on trees, in the streets and in the stores were old-fashioned light-bulbs giving off a warm glow. When I was very young we even had candles at our tree at home, although I admit, as romantic as this was, it probably increased the fire hazard quite a bit.

So today after reading in the local press that our little town would have a "Christmas-light switch-on" with a firework afterwards, I thought I pop down and get a little "into the mood".

The problem was, after the lights were switched on (streets and market place) I got a mega-headache, became nauseous and kind of staggered home in the dark avoiding the switched-on streets as best as I could. I always had problems with LED lighting and avoided it mostly, but it seems to get more and more!

White/Blue lights seem to be particular difficult and I wondered why on earth any designer with a brain would use these cold colors for Christmas decoration??

I know that the C's talk about "strobe-lights" and their hypnotic effect (will try to find these excerpts in a minute) and I am aware that this is a different kind of light, but I feel that there is something going on with LED lights as well.

Doing a quick search online I found quite a few people with similar symptoms as mine, but also others who find the lights, esp. the blue ones, calming I also found this:

Melatonin suppression
A team of researchers from Israel, Italy, and the U.S. are now saying that the light emitted by a white-light LED suppresses melatonin in humans at a relatively high rate. Melatonin suppression is apparently not a good thing, causing "behavior disruptions and health problems," as noted by a University of Haifa press release on the study. This is because it disrupts the circadian rhythm.

The researchers compared three types of bulbs: white LEDs, metal-halide lamps (used in car headlights and outdoor lighting), and high-pressure sodium (HPS) lamps. Melatonin suppression is caused by blue light; HPS lamps, with their orange-yellow hue, were the controls in the experiment. The results showed that metal-halide lamps suppress melatonin at a rate more than three times greater than the HPS bulbs, while white LEDs suppress melatonin at a rate more than five times higher than the HPS bulb. The study, titled "Limiting the impact of light pollution on human health, environment and stellar visibility," was recently published in the Journal of Environmental Management.

Melantonin, being connected to the pineal gland or "third eye", so another method to keep up asleep, dumb and hypnotised?

Here is the session about strobe-lights (18 November 1995)

A: Strobe lights are used for 3rd density mind control.
Q: (L) Strobe lights located where? What brought that up?
A: We have picked up your thought waves, which are progress oriented, and are trying to assist you in your increased learning and progress frequency wave. You see, this increases the energy level!!
Q: (L) Okay. You mentioned the strobe lights. Are these strobe lights that are used to control minds, are these something that we would or might come in contact with on a daily basis?
A: Do you not already know? We didn't say: some strobe lights, we said: strobe lights, i.e. all inclusive!
Q: (T) Strobe lights come in many forms and types. TV is a strobe light. Computer screens are a strobe light. Lightbulbs strobe. Flourescents strobe. Streetlights strobe.
A: Police cars, ambulances, firetrucks... How long has this been true? Have you noticed any changes lately??!!??
Q: (F) Twenty years ago there were no strobe lights on any of those vehicles mentioned. They had the old flasher type lights. Now, more and more and more there are strobe lights appearing in all kinds of places. (L) And now, they even have them on school buses! (T) And the regular city buses have them too, now. (L) Okay, is the strobing of a strobe light, set at a certain frequency in order to do certain things?
A: Hypnotic opener.
Q: (L) What is the purpose of the hypnotic opener being used in this way?
A: You don't notice the craft. Opener. Is precursor to suggestion, which is auditory in nature.
Q: (T) What suggestion?
A: Put on your thinking caps. Networking is not making assumptions. Bold unilateral statement of "fact" is.
Q: (T) Oh. Phrase your statements in the form of a question! Cosmic Jeopardy! I'd like "Hypnotic Openers" for $200, Alex! (L) Okay, you said the "suggestion is auditory in nature." If this is the case, where is the suggestion coming from in auditory format?
A: Where do you normally receive auditory suggestions from?
Q: (L) Radio, television... (T) Telephone... (L) Is that what we are talking about?
A: Yes.
Q: (L) If you encounter a strobe while driving, or you are sitting in front of your television, then the suggestions can be put into you better because of this hypnotically opened state? Is that it?
A: Yes.
Q: (L) What are these suggestions designed to do, to suggest? In a general sense? To not see the craft?
A: Yes.
Q: (T) Do we get these signals from the radio in the car even if it is turned off?
A: Depends upon whether or not there is another source.
Q: (T) Another source such as?
A: ELP, for example. Extremely Low Pulse.
Q: (T) ELF, Extremely Low Frequency, and ELP, Extremely Low Pulse - is this the same thing?
A: Sometimes.
Q: (T) This would be an external pulse or frequency?
A: Yes.
Q: (T) Would it be originating from the source of the strobe?
A: No. They act in unison.

LED's are becoming impossible to avoid.

They are everywhere. Cars (inside and outside), TV's, Cell Phones, PC's, Home lighting, Office lighting, Street lighting, Advertising boards, torch lights, etc

The perfect "energy saving" bulb replacement.

I work a fair amount of time on my laptop and this combined with watching TV, checking updates on cell phone; I wonder what the effect on flashing lights have on my brain and memory function...

Some LEDs actually flash, like in tail lights for cars. In order to vary the brightness, they use a PWM signal (pulse width modulation) since LEDs are not really dimmable: they're on, or they're off. So, they send a square wave that becomes not-a-square-wave... IOW:

High = on, low = off.

Thus, they flash too fast for the eye to see, et voila! You have a "dimmable" LED.

That would seem to be more potentially harmful to me than just a regular LED lit up, since it's simply producing light (albeit usually more intense light).

Personally, I've never noticed any ill effects from LEDs of any kind, although I have noticed that some car tail lights are sort of "annoying" for lack of a better word.

Thanks for your input.

Yes, they are becoming impossible to avoid :/

There are two other threads with similar topics:

Here the effect on melatonin is explained very well.

I haven't read the threads in their entirety yet, but both carry a lot of suggestions how to help your eyes cope with the strain.

Interesting, thanks!

I looked at a few pictures of Christmas Lightnings in big cities worldwide and it looks rather horrible to me. Attached are two pictures, both Paris ...

I also suspect that being ketogenic renders you more immune, so it's kind of a wake-up call for me ...

Funny I was thinking about that particular session only last night. That was because in the cafe next to where I was sitting they had put upa projector to project on a screen by the side of me for a football match (I was going to leave anyway because of the football!), but, the light from the projector stil came under the screen and light white/blue then strobing as the colours showed different pictures. All made me quickly dizzy but the white/blue was so powerful it quickly felt very painful even when not looking at it directly. Certainly no-one could have stayed in that chair!

I certainly thought I could have been at risk there of having an epileptic fit, though I never had one before. Extremely uncomfortable.

I find it bad enough just adjusting the the clocks going back. The early darkness so confuses the body/mind especially for SAD sufferers. I was thinking of trying to plan my life as if it hasn't actually been put back. I have not worn a watch for over 5 years now and the time is on my mobile anyway. So getting up earlier may help with the energy levels as psychologically I seem to have far less energy once it is dark!
