Yes, they are somewhat bright.
Very handy if there's a "reset"
But Ninety? At 90 hours it's running at 0.140 lumens! ~140L for the first few hours..
These LED's are driven hard at ~28mA
~0.850mA x30 at ~3.7V There's probably no current limiting resistor or driver. series/parallel.
An easy MOD would be to attach it to a power bank with proper current limiting.
(for the soldering crowd)
