yea sorry man your in the Stone Age with that thinking. The Samsung tech is tested. It’s proved, wejust upgraded our biopharm site with the same diodes, different spectrum but same diodes. They did this because in the clean cores they can’t be having bulbs changed. Further there are numerous real studies showing the benefits of these over traditional HID lighting. They are the future. Every thing you have said to the negative I haven’t seen, no one I know has had a single issue with the quantum boards , and while we have stayed with more HLG products mainly due to service but also because they started producing288 boards in theUS. You want to talk about bulb issues, traditional HID lighting has them like crazy. You want to talk efficiency, ability to adjust Intensify with no spectrum swing (you throwing off light that’s not the ideal advertised spectrum if your dimming yours) it’s proven to kill. as far as long term reliability well I have punished some of these with over max power, ran for over a year with only power outages to given them a rest. No issues. I have sprayed and slipped and nailed the boards- no issues but not advisable. All my power supplies are located remotely and have nothing to do with the boards when your taking about reliability- un related manufacturer- but again the ones I’m running will run for many years with no issues - they are tried and true
