What about a Sofrin SP10 Pro? Although it is a 1 AA light with Anduril 2. Not sure how well it would perform when the floor and ceiling set to the 5 lumen range.
+1 for the Sofirm C01 at 3400K from Sofirn Store on AE and they also have the Red LED in same form factor.
If you are so inclined and prefer more runtime, a warm 5mm LED tweaked to fit a 2xAA Maglite might serve your needs as well. The tweak is a matter of resizing the LED and reflector, then pairing with rechargeable constant 1.5V lithium you can get consistent regulated output for days.

Those gchart joule thief drivers are excellent. I swapped one into aNOS four sevens atom along with a 219b sw35. Just an awesome little light. I agree with others, though. Sounds like the Sofirn c01 is exactly what you want. Alternatively perhaps peak can make an Eiger to suit you?
Search for medical pen lights. Most have a very warm emitter, several good ones to choose from (and they aren’t priced like typical “medical” tools, thankfully). Lots of the weird-name cheapies do use a 5000K or 6000K emitter, though, but most of the med-specific stick to 3000K.
Weltool has a couple…not sure if the multi-mode brighter ones would suit you but single mode does limit your choices. Nitecore and Streamlight have some that I know are well regarded by EMTs and nurses, and seems like Wuben and Lumintop also have one (but I think the Lumintop may not have a suitable mode for you if memory serves).
I used the very light you’re looking for tonight. 2xAAA incandescent maglight. Mine with eneloop is quite warm 2300-2500CCT maybe. Only one mode and right around the lumens you want. 100CRI to boot!
Wurkkos WK02 penlight. 2*AAA, moonlight mode and 4000k SST-20 95 CRI.
Maybe they have them on their site if you don’t like AliExpress.
There’s also. WK01 that’s a single AAA but the warm version is sold out.
Nah. I have a Lumintop iyp 365 which is very nice if you like MLH mode order. I use the Ultratac A3 at work for its LMH mode order and it’s very very decent. 219C but very good tint.
Both have beam patterns like every other AAA sized reflector led out there.
The nice thing about one that I linked is that it has modes but always comes on in the lowest so you never flash a patient accidentally. They’re specialty lights, though, not really at all like most pen lights or our regular small cell lights.
