I’ve recently gotten a Wurkkos HD15R with the 660nm SST-20 deep red to use as a light for reading before sleep. I’ve read before that melatonin is suppressed by light, especially blue light, less so green light, and essentially not at all for red light. But the effect is much stronger than I expected. Less than one hour into using it as the only light in my room, I already feel intense sleepiness. Makes me wonder how much we are damaging our sleep willingly in modern society, and resorting to taking various pills as a quick fix.

I use an E17A 1850k on candle mode with sunset timer when I go to sleep and it’s perfect for that. I tend to use Deep Red from an LT1S Pro sometimes when I’m working late and my eyes are getting tired as it’s easier on them than white and keeps the light mostly around me.

I try to have no light if possible, but the problem is that everyone and his grandmother uses blue LEDs for f’n everything.
Clock? Blue backlight.
Router LEDs? Blue.
Plug-in voltage-readout thingy? Blue.
Blue, blue, blue. Every f’n thing blue.
You can’t even get things with other-color indicators, readouts, backlights, etc.

Yeah it’s ridiculous. You often can’t even block it with a piece of electrical tape - it just shines right through the cheapo plastic housing.
I agree. Though I think red indicators are also common for number readouts. I think they are the most comfortable to look at, anyways.
A close friend recently told me that he uses red light at night, a Fenix with red plastic film over it…
So I put a 660nm Red into this SC21 Pro as a gift:
I just love that host, and Anduril works great w red LEDs… no need for a special driver.
Set it to max-brightness “lightning” mode in an otherwise all-dark house…

I’m gonna do that tonight! Assuming we don’t have another crazy thunderstorm.
seems like total darkness would work better
also advantage - totally free!
no batteries to f* with
Well, darkness is preferable, but red light is useful for reading or doing anything else.

I’ve been looking into this too, for sleep reasons. Infra red light is ideal. I’ve just been looking at the sofirn hs41 which uses 4 sst20 leds. This would be awesome for reading in eco mode if it had a red light. If this headlamp used just one sst20 for eco then it should be possible to swap that one sst20 for a SST20-DR Red LED, which produces red light in the wavelength of 660nms (ideal). Sofirn actually uses this same led in their D25LR headlamp.
Did you do DR emitter in the SP10 Pro as well? I can’t recall if the moonlight on SC21pro is the same as the very low moonlight on SP10pro. I’m thinking about doing one in either of these hosts because of the anduril. I really like the super low on the SP10 pro.
SC21 Pro has a low of 0.2 with stock firmware, but with a reflash it gets as low as the SP10 Pro of 0.02
I prefer having the illuminated button and built in charging of the SC21 Pro. I dont use AA batteries, I like rechargeables. If Im going to recharge anyway, I can just use LiIon. I also like the SC21 Pro reflector better, it makes a tighter beam
when I want floody, I use a Pebbled Tir in the SC21 Pro. The Tir does not fit the SP10 Pro.
Infrared is useless, as you can’t see it. In theory non-deep red should work just fine, and it would be more efficient as your eyes are more sensitive to it.

Infra Red at 800nm, penetrates deeper into the body than Deep Red at 660nm.
Infra Red has an advantage for applications such as deep muscle therapy, just not as a flashlight.
I believe the 660nm is better for light use. I mentioned infra red because that is the ideal - it’s mimicking sun exposure to your eyes (the real deal). It helps you make decisions in other areas, for example bar radiator heaters and those ixl light globe heaters. You can set up a bar radiator heater in your bathroom, same as the ceiling mounted ixl globe heaters (one or the other). It’s another way of increasing your infra red light exposure in a useful (win/win) way into your everyday life. Sitting by a window to read by natural light etc etc. Near infra red probably doesn’t help melatonin production, but it shouldn’t hinder it either - which is what other lights do. Less exposure to other light is better, so reading with a red light rather than a white light is a win / win.
Weerapat and sofirn answered my question re the sofirn hs41 headlamp - it uses all 4 leds in all modes. Considering these are sst20 leds would there be much involved in swapping these out for SST20 DR 660 nm Red LEDs? I’ve read somewhere that the 660nm version of these LEDs should ideally use a different driver. I’d get the wurkkos or sofirn d25lr but I’d like to stay with 21700 or AA batteries.
Is this medically proven or just your personal experience?
Many people cant sleep without the TV on. There is no scientific reasoning for this. Just personal preference.
