Emisar D1K UV emitter fried itself. Bit of a bummer, but I've already reached out to Hank. Anyone else run into this with the 5W UV emitter?

Ooh yeah that’s a goner. I wonder what happened. Usually it takes a lot of extended heat to do that and that would be hard to do given the way hank sets up his lights.
It could be anything from a driver fault to a short. Just replacing the led won’t be sufficient.
Maybe a bad reflow giving poor heat conductivity to the MCPCB? Since the temperature is measured at the MCU, that could result in an LED overheating without the MCU going into thermal protection in time.
