Extract:


May 2013 light1 888  light2 911
May 2014 light1 829  light2 851
May 2015 light1 773  light2 792
May 2016 light1 718  light2 738
May 2017 light1 669  light2 686

669 / 888 = 0.753378
686 / 911 = 0.753019

Both lights decrease about the same
How does this work out for half-life?
These are the bare tubes.

My tritium light in a big block of transparent plastic,
hanging in the bathroom, has not decreased noticeable.
But a factor .75 is hard to see.
I am sure it did get dimmer.

Clean it? Any smokers?
