Updating a 70,000 hour lamp
Added 2022-11-03 04:54:28 +0000 UTCI didn't realise how old this lamp was until I made this video and discovered that this lamp has been running 24/7 for over 8 years!
The only failure was degradation of the blue LED, with a slight reduction in intensity, but more importantly, a discolouration of its lens that affected it's output adversely.
A new blue LED has been fitted and the lamp is now back in operation.

It was subtle and didn't show well on camera. The much larger chip in the new LED probably didn't help with the focal qualities of the lamp.
