"10 watt" LED
A while ago, as an experiment, I bought a 12v outdoor landscape light that claimed 10w warm white. TO NO one's surprise it did not consume 10 watts, and while it did respond to a PWM LED dimmer, th...

Seventeen moolahs for a ten watt driver is beyond what my wallet is willing to part with. And yes, a person has to be careful when buying light emitting diodes or accessories off of eBray.
None of the drivers I purchased have failed from the vendor listed above. Near 100% chip failure of integrated housings/chip assemblies.
The SHARP 30 and 50 watt chips I purchased blow the doors off of the chips I purchased from Mickey Mouser. Better sunlight color, cooler running, and more uniform segment illumination.
For 120vac to 36 volt conversion I use ventilated power supplies. That way I can tweak to match ma to specifics. For instance over my new work bench I backed off voltage to 34.4 from 35.8 (4%) on a 50 watt Sharp chip.
So, as far as I am concerned "blanket statements" about LED components are risky. A Truism however seems to be any 120 vac LED lamp assembly from China should be treated like the electrical components are sub-marginal.
