Stupid question

I tried search and just may not word it right. I built my lights about 5 or 6 years ago. I used Vero 18 cobs. Do leds and drivers weaken over time like CFL and hid? I'm chasing a couple problems and strains I have worked with in the past (same seed stock) just don't seem to do as well now.

It is more then just the lights, almost like I have forgotten what I'm doing. I was under the thought that leds never weaken. A friend told me he had to change his lights cause they got weaker. So I'm asking, just in case I need to do that as well.

Only reason I asked is because you made it sound like your issues are arising from your 5 year old light?

They most definitely do degrade over time, but not enough to ruin a crop imo.

Ok thanks, just trying to rule everything out. I have been thinking about some new lights but looks like I have some more time on them. Thanks everybody.

You said "same seed stock"? As in, the same seeds you were running 5 years ago? In my experience (20 years ago and a life time away, admittedly), 4 or 5 years is about the point at which my seed stock started to get a little long in the tooth. Seeds weren't bunk at that point, but I definitely noticed decreased vigor over all, as well as a decrease in germination rate.

Not saying 5 year old seeds are worthless, but they are worth less, if you catch my drift.

Unless they've been stored in 120+°F attic or similar, 5 year old seeds should be perfectly fine.

Yes, moreover then originally mktd especially when not coupled with proper thermal mngmt or ran anything but soft w/o air movement.
