Filament LED Long Term Test: 5000 hour datapoint

electronupdate · Nov 24, 2015

A while back I tore down a filament LED and many questions were raised if the filaments would be reliable. An interesting question.

I have had a bulb running continuously for most of this year and it just passed the 5000 hour mark.

Video of the results to date, below:

This is good to know, since my 3 new bulbs (identical looking to yours) arrived from China just 3 days ago. (One set of filaments were bent to one side of bulb, but it fired up. I didn't feel like driving back to Zhongzheng to return it. )

I admire your work here. I am guessing you tested the 4 filament version. Now, go test the 6 and 8 filament versions.

If that 640 number is lumen, not lux, you probably tested the 6 filament version?

Ah, good catch. The axis of the graph should read lux.
