This light is not a typical diy light - it’s built with quality components, good engineering, and name-brand components.
This light should last a very long time, practically forever, and is night and day difference:
The cooling is done with a large passive sheet of aluminum. No fan to fail. The temperature rise is reasonable, giving long led life.
The power supply on the light is name-brand MEANWELL. The power supply construction is good, expect this to go out first after 10 plus years. I’m ok with that. Some smaller ones still use quality supplies, which I haven’t seen.
