Cree 5000K Daylight bulbs make me warm?
-
Ok, I don't know where to ask this on the internet. I feel safest asking here because I know I won't get trolled.
I have a small bedroom. It's just over 10x17 feet with an 8-foot ceiling. I have two 3-way floor lamps that normally have my 3-way SWITCH LED bulbs in them. The one furthest away from me is always at its highest setting, and the one right next to me (a foot or two away) is either off or at its lowest setting. Sometimes I have it at its highest setting, but that's usually during the first few hours of my "day". I've lived in this room for about 1 year now.
Ok, so these bulbs are supposed to be 2700K. The light is very nice, and I've always loved them! I still do. They're very difficult to beat (and as you'll see, they still are).
I discovered last night that, thanks to my parents, I have two spare Cree Daylight bulbs (the original design, not the new design that they have now): one 100W equivalent and one 60W. These are supposed to be 5000K. So, I thought that this would be fun to try. I figured that maybe these could be what I use when the bulk of my daytime ends up being at night right between sunset and sunrise, especially if I wake up after sunset.
So, I stick them both in and turn them on. Wow. PERFECT! Well, the color spectrum is pretty narrow and I can tell that there's a lot missing outside of 5000K, but hey, they're bright and alerting. Awesome. DONE DEAL.
WAIT, MAYBE NOT. So, I noticed after a couple of hours that I was a lot warmer than usual even though nothing was different at this time of the night. Same temperature, same humidity level, same air conditioning setting, same diet, same everything. I was so warm that I actually had to remove most of my clothing, but that didn't help. I was confused. It even felt somewhat humid in my room. I was getting concerned that maybe our air conditioner stopped working. Nope, it's fine! It was all me. Maybe.
Well, I went back to my SWITCH bulbs and to my surprise, I started feeling cooler and cooler. NO WAY. Is this possible? Could those lights really be doing that to me? They don't get any hotter than my SWITCH lights. Actually, they run a little cooler. I don't get it. Maybe the higher alerting quality makes my heart beat faster, like taking caffeine or something.
What do you think?
Edit: I might keep experimenting with these lights just to be sure.

Just seeing this now. That is a really interesting experience! Did you use them during your normal waking hours or might you have blasted yourself with light at a more sleepy time, like after you'd sat through sunset? I can tell you that some lights make me feel very strange, but I've not had that experience before.

I might have to keep testing (I kinda don't want to though), but every time I have tried to use these lights, I always end up feeling like the air is warmer and a little more humid, but it can take like an hour for this to begin happening. I've tested them in various conditions since then, like in the middle of the day with my blinds closed and then again in the middle of the night when the middle of the night was just like my late morning, and every time I end up turning them off and going back to my SWITCH 3-WAY lights. As soon as I do, I start feeling cooler. There's no delay; it's instantaneous. It seems to make no difference what time of day it is, whether I just woke up or whether I've been awake all "day".
Now, I'm sure someone could say that this must be due to a higher heat output or heat radiation, but it's not. They run cooler and they even take MUCH less time to cool off. If I were to get a frying pan to be precisely the same temperature as the 100W equivalent Cree Daylight bulb and attempt to cook an egg on it, I'd probably fail. With the temperature of the SWITCH 3-WAY's heatsink though (when I have it on its highest setting), omg. I am sure I could cook an egg on a frying pan that's heated to that temperature. So if anything, the room should feel warmer with the SWITCH lights.
So maybe my body and brain are trying to react to the 5000K light in the way that they're used to from natural full spectrum sunlight, but it can't "use" the light but keeps trying and is causing me to heat up. I may never know.

Incandescent bulbs have orange hue and LEDS, especially early models, tended to go more blue. Blue wakes so that would warm you. To test this theory try CFL bulbs since those emit the most blue.

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.

The new Cree soft LEDs are great; buy at Home Depot. Very similar to incandescent. I use UVEX Orange saftey glasses at night.

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.

Well, I have a question then. Why would I get one of those if I already have these awesome 2700K SWITCH 3-WAY lights? The light they emit is beautiful and very much like a real incandescent, except for the super-fast flicker that you can see if you wave your hand around or have a fan on near the light.
The whole point of trying those Cree Daylight LED lights was to have much more alerting night in the middle of the night when the middle of the night happened to be my daytime.

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