What strikes me as extremely odd is that the vast majority of electronics not only work more efficiently, but tend to last longer at temperatures near but above freezing. Almost sounds like you have an iffy power supply or driver...

Almost sounds like you have an iffy power supply or driver...I thought that we might have had some sort of power issue because the north end of our screen printing building was underpowered in the summer months when we'd start running the personal AC units. We had the electricians in and we essentially let them do everything they suggested and that included having a line ran dedicated specifically to the expo unit and only it. So if there was a problem before, there isn't one now. That day with the electricians ended up costing about $5K with all of the things they did.Oh, and nothing changed with the expo unit unfortunately.
Power should not be an issue. The LED's run off of a power supply that should keep the power constant. Just a FYI
We were grasping at straws honestly. I can say I've tried everything in my power to make sure we weren't the problem. No problem, I was wondering what was going on but don't worry, I hadn't gone full-confused yet.
Pierre -- with all your testing goodies, do you know of a (low cost) device that will give a spectral output of a light from say 300nm up to 450nm heck, what's even the name of a device like that?
