Default A 2200lm 7057 LED car lamp...

I ended up finding one of these bulbs and tried lighting it...

WOAH yeah I think 2200lm is about right - it's blindingly bright. It's yellow unfortunately, but that's expected to be 7057 replacement.

From what I found it's 12V 1.75A so this thing is dissipating about 20W, though unsure how much is light vs heat. It does get hot fast - cannot hold onto it in about 20 seconds. Not sure how much of the metal frame is actually functioning as a heatsink or not.

I do wonder how long this thing will last if I run it 100% duty cycle, I suspect it was intended for blinkers with much lower duty cycle?

Note that at 2200lm, this is brighter than a 100W incandescent rated at 1600lm.
