Usually when 1 LED fails the whole string of 1 will fail
example QB 288 has 16 strings of 18 LED
IF an LED fails then all 18 will faill

Then I guess you won't know which led it was that failed either if the whole string will go. Perhaps for some that'd be even more reason to go with solstrips if this was a worry because you can very easily swap that unit out for a brand new one and with solstrips you can easily swap out individual X2 strips for different spectrums. They're essentially the same just the strips are strips and the boards are really more board like lol
I bet the QBs will take a good 5-10 years minimum at full blast before anything like that will happen, and a few nasty knocks maybe.
I'm having lots of fun deciding how far apart I want my strips and what spectrums where for what Kelvin.. I've been bitten by an LED DIY Bug... sigh that and my usual seed bug addiction (more of a praying mantis mind take over) has got me penniless. haha grower problems
