Are you expecting the cheapie driver to short and produce enough heat to make the metal shade glow without tripping the fuse? That would be very unlucky...

Post by: yui on Tue, 17 November 2020, 02:17:37: from my experience with cheap LED driver they undersized the transistor that gives up in a few months or the bootstrap capacitor fails from the heat of the transistor in both cases your lamp will not fail catastrophically, it will either not turn on or blink...
bottom line buy a few spares for when it fails.
