Any modern LED headlamps (or any lights for that matter) that put off a more natural amber colored light?
The new blue LED fad is not good. It's known that blue light, especially at night is terrible for health.
It stresses mitochondria & circadian rhythms. Search for ' Jack Kruse blue light ' videos for more in depth info.
I personally find that the blue light is actually irritating & makes it harder to see things as the contrast is so out of range with nature.
I've seen some clip-on book lights that came in amber, but never a headlamp. The best option might be to get one with interchangeable lenses, and paint one of the lenses with the kind of paint used for faux stained glass.
This is a huge pet peeve of mine, but LEDs are out there in the 'good' wavelengths.
You may need to try a couple to see what you like; 3500k? 4500k?
The lower the number, the warmer/yellower the light.
You may also find 'high CRI' light nicer. Colour Rendering Index.
Searching for 'neutral white LED, 'daylight LED', 'warm white LED' headlamp/flashlight will get you somewhere.
I use mostly Convoy flashlights, but their headlamp is subpar. Great cheap utility lights that can be found in a variety of wavelengths to see what you like.
My Skilhunt headlamps are about as cheap as half-decent headlamps come. One has failed after a couple years.
A better grade for a primary headlamp is worth it to me; my Armytek was much nicer, but after 4 years died and warranty service seems to have eaten my light, so won't be getting another of those.
Zebralights are premium lights and headlamps, really nice, and will probably be what get for a new main headlamp.
I use mostly single 18650 powered lights including all my headlamps, with a couple single 21700 and 22650 lights for longer ranged stuff. I don't run lithium ion batteries in series for safety reasons. You can get AA and AAA lights with good LEDs, but performance suffers substantially..
For battery area lighting some of Milwaukee's LED stuff, branded as 'True view', uses warmer, good quality LEDs. I've been using one as 'temporary' primary lighting in my tinyhouse for a couple years now..
