I know that this isn’t the light OP is searching for, but this thread seems like the right place for it - the Warsun X608 with 2x Osram P8 and a side-firing COB and inbuilt battery + powerbank function.
16$ with a code from Fin17: Archive topic - Banggood & Fin17
I have this light and I really like it.
It’s not easy to disassemble, but the batteries are really 4Ah, the light colours are all not blueish, the UI is good and the light gets warm after a short amount of time, to the LEDs are all cooled.
Only negatives are the micro-USB port instead of USB-C and that it’s not disassembleable without being destroyed.
Perfect for testing out if that formfactor is suitable for you.
