I noticed that virtually all LEDs driver resistors are two vastly different values, in parallel. Such that if you snip off the correct one, you are left with a slightly lower output light, that consumes half the power and last many time longer.

It's like a secret cheat code for people in the know. It's almost a conspiracy.

Just cut off the highest value resistor with a pair of snips.

This is a really good tip. Although ripping them apart is the last thing I'd like to do when I buy a new set of lights I might have to start doing that.
