@dbrn32 I don’t think the 50,000 vs 100,000 life expectancy of the chips really matters to me, unless the performance of the chips diminishes significantly over time.
It’s the difference between 7 years and 14 years at 18 hours per day.
If I have to replace the boards in 7 years because I saved 35 or 40% up front, that’s a fine trade off for me.
If my yields are lower, I will yield plenty from this set-up, I’m ok with that.
But if the quality will be significantly different it does matter to me, whether it’s out of the gate or 3 years from now because the epistar degrade faster.
