What light should I buy

The test data must support some type of prediction but I'm not sure how it's reached. I remember church haze saying hundreds of years if the current is low enough. I assume much lower than the currents we are using, but still it gives the idea the lifespan can be extended exponentially. Perhaps he will chime in.

Would love to see similar data for cxb 3590, 3070



Edit: 10000hrs is about 2.3 years with 12 hrs per day
Data is @2.1 Amps Vero 29. Lumen maintenance will be even better at 1.4amps

Five years still ain't bad- I see precious few other lighting options lasting anywhere near that long.

I'm on my phone so I can't dig it up very easily. But start here...http://www.cree.com/~/media/Files/Cree/LED Components and Modules/XLamp/features/Cree XLamp CXA SD Large Feature Sheet.pdf
