I don't know what happened to my post of a few days ago - I thought it was being moderated - but here it is again.
The led I reported on in July 2015 is STILL going, though even more faintly.
After 10 mins of adjusting my eyes to darkness, it was just about visible.
Anyone got any idea of how to measure its brightbess, even when it becomes invisible to the eye?
Cheers,
Graham
