I have been on the hunt for a pair of reasonably priced(!) warm white lights for my gopro. Have I missed something or ~4000K, 95 CRI is STILL rainbow unicorn category?

Apparently little $ can buy loads of lumens on Aliexpress, but those are typically 6000K and digging deeper, poor CRI/spectrum. There are lights with combined LED's, where you get a few warm 3500K LED-s in it, BUT after little research I found some horrible CRI figures for those warm LED's too! E.g. this beast claims to have "4 pieces of XHP50 LED yellow light (3500K)". Now checking the documentation, I find a poor 70(!) color rendering index and a spectrum with a Mariana trench @ 480nm (most likely the reason for those terrible CRI's). As water likes to absorb red very quickly, I am leaning towards WARM lights but definitely with a more even spectrum. Absolute worse case, I still have a pair of Tungsten lights but they are ofc super power hungry (100W each) and require a heavy battery, something I am not keen travelling with.

TLDR: any recommendations for reliable, serviceable (e.g uses standard Li batteries) video lights that preferably don't break the bank?

I have not found anything in the warm color temp, and CRI numbers seem to be nonexistent.

Edit: Keldan quotes CRI, but they are very expensive.

The Backscatter HF-1 is not cheap, nor does it have warm color temp, but it has a lot of light available so you could add diffusers/filters to warm the light at the expense of lower output.

Bluewater has a 3000 lumen video light with a nice looking diffuse beam at 6500k for $250. I don’t see a CRI listed. If you put a diffuser on it the color temp should drop below 6K. Not experience yet—I have one ordered.

I’m just getting into lighting underwater, but have been told color temperature is less important as long as you set the white balance. Maybe others more knowledgeable will comment.
