i used the superbright 5050 SMD cool white 300 LED
when i did fluorescent conversion over 2yrs ago
the small 18w Fl over the kitchen sink got (2) strips,
it is almost never turn off, it is mostly on 24/7
and every LED is still on (hey they may die tomorrow)
the light over my left shoulder gets used about avg of 10hrs a day , 3 strips
(1) LED has gone out, im going to add another strip to help these aging eyes
(4) other fixtures (2) 30w size (2) 18w size all work perfectly with the strip LEDs, all of them get used on/off thru out the evening or night
(6) FIXTURES total
all these lights have thousands of hours of use, the kitchen light over 14,000 hours
guess i'm one of the lucky ones,
I can explain it to you.
But I Can Not understand it for you !
