There's a flicker in the LED ropes I bought. Cool white and orange, the former being a lot more infuriating.

The blue Incandescent is nice though, more like aqua/green. Should I discuss the flicker with the company? My Ben Q monitor doesn't have this issue nor do good quality LED bulbs etc.

Are you saying that the Red (in RGB) is not actually red?

No, I'm not saying the red will be pink, that was referring to the beetle night light I provided a link to, red should be very red on your lights. If you have a deep blue colored dish or bottle, hold it up to the light. I promise this works, if you see any pink, (it's not deep red / black) then there is some blue light. Let us know!

There are some LED lights that can use the ballast but it decreases the reliability of the light.

See http://www.designingwithleds.com/ for more info.

No there have to be some reflective material, be that glassy mirror, shiny metal or whatever shiny. In case that sides of tunnel will be just white, it would lead much less light. So it would be inefficient and only wasted money and/or your work. Let the metal there to do it's purpose and just cover the hole with something that blurrs the view into the tube so you won't see the metal. I would do it this way.

That's what I'm saying. Like I said, "Maybe the higher alerting quality makes my heart beat faster, like taking caffeine or something."

So, I guess the real purpose of this thread is just to see if anyone else is experiencing this. I would say that I've already concluded that the most likely explanation is the higher alerting quality of that light. However, this doesn't happen to me when the super bright light of daylight is flooding my room on the brightest part of a clear sunny day (and no light in the world is as alerting and energizing as that). I tested this by simply turning off these Cree Daylight bulbs when the sun was shining directly on my window and it was in the highest point in the sky. As soon as I turned the lights off and opened my blinds, I began feeling cooler just like when I'd simply go back to my SWITCH lights.

So this is rather odd in my opinion. Like I said, perhaps my body is stressing out and overheating. I don't know.

You cannot draw a conclusion using one model of led light. Like I said get some CFL lamps and if same reaction then it is overabundance of blue spectrum. F.Lux removes blue spectrum to get you ready for bed.

I think you're missing the whole point of why I tried those spare Cree Daylight LED lights.

Yeah, it's really like a candle yellow, very strong. I could see it being a bit much and it's very easy to make a preset like I have in Hue Pro (wonderful app).
