I agree on this. Since the uvb/c leds are so inefficient the actual amount of heat the chip has to deal with would be almost double of what a standard white diode would have to deal with at same wattage. Another approach would be going for more and cheaper uv chips and run them soft. Now with covid there are many new options since there is a new demand.Looks like a decent chip. All UVB led are piss poor efficiency which correlates to higher operating temps (per watt input), and reduced longevity compared to visible spectrum LEDs.
Another thing to think about is hanging height: if 15mW output is ok for 12", assuming inverse square root reduction in intensity, then 4mW per diode should be ok for 6" which is where our lights hang. 4mW outout was around 40mA on the last chips i checked. Means about 10x less watts and heat per diode.
