Should this work according to the study?
dd99 said:Thanks, cantstoppeating, that's interesting. But it's counter to what others have said in the forum about the spectrum of warm white LEDs, which appear to have a spike in the blue wavelengths. I'm on my mobile, so can't post images, so here are some links with graphs:

In addition, there appears to be some risk of eye damage from (admittedly cooler) white LED lighting:

I personally find LED lighting irritates my eyes, unlike halogens or incandescents which have better spectrums. (My brother in law is a TV presenter and they've had to remove LEDs from the studio because of the high frequency flickering and irritation to presenters eyes when they look directly at a light.)
The best and reddest, of course, is candle or fire light.
...At the end of the study, the amber lens group experienced significant (p < .001) improvement in sleep quality relative to the control group and positive affect (p = .005). Mood also improved significantly relative to controls. A replication with more detailed data on the subjects' circadian baseline and objective outcome measures is warranted.

It lasted 14 minutes. I felt good at first then felt over stressed from too much stimulation at once I suppose.
I am unsure if the bulbs are very good (flouro) despite being 633nm.
If you feel over stressed that means your glycogen is empty and/or you use it too long. You need to eat and get your glycogen full first before using red light therapy.

I spent a long time deliberating over changing all our lighting (50-odd lights) to warm white LEDs from halogens for the long term cost savings, but my research (both theoretical and practical) led me and my wife to conclude that incandescent > halogen > warm white LED > cool white LED > CFL.

Trouble is, they run so damn hot. (halogen).

High pressure sodium?
I think there are two types. The aluminium reflector halogens push the heat outward, so they feel hot. But if you have a fitting that can take the heat, non reflector halogens let the heat dissipate into the fitting, so feel much cooler.montmorency said:https://raypeatforum.com/forums/posts/96633/dd99 said:https://raypeatforum.com/forums/posts/91460/ Yes, tara, that's right.

Thanks. Had not heard of those. They look quite interesting.

Do they run cooler than incandescent? They supposedly have similar light characteristics.
Such_Saturation said:I think they could be the holy grail of Ray Peat lights, personally. They mostly need the larger lamp screws unfortunately. They also have internal pressure which might make them delicate. But they range in pressure and can do the whole orange spectrum or the whole red spectrum, with much less infrared than incandescent or halogen.

I look forward to you riding this to ground, Such!
