A few years back BigClive did a great run of videos on the now ubiquitous Normal LED Bulb, how they're driven, how they're usually overdriven to make them die faster, and how to chill them out by replacing their current limiting resistors.

I tried my hand at such a mod today, grabbing the first bulbs in my stash that looked about right.
Can you guess which I've already messed with? Anyway, the long and short of it is to clip or rip off the original surface mount current-setting resistors and plonk on a 220 ohm resistor to the same points, and it gives you a light that'll last for many many more years than it originally would, and divides the original output by 1/10 or so for most bulbs.
The unmodified bulb, original resistors by R4 and R3.
Modded with a 220 ohm resistor. The spring clip is common with the now empty right resistor pads.
The camera really mutes the difference between the two, but subjectively the one on left is about 1/4 or less bright than the one on right. The reflection on the ceiling tile/metal is a decent indication of the difference.
Now the kitchen can be minimally lit anytime.
