@blogzilly Don't be so damn hard on yourself mate! I generally don't consider myself to have my head up my arse but this is an ENTIRELY new thing to me ( and goes some way to explain some damage I experienced a few years ago that sounds remarkably similar to your situation which I never got to the bottom of).blogzilly said:SNIP
Gotta step up my game, that's all. Just frustrating to see something that could have easily been avoided if I didn't have my head up my ass.
Ever heard of the Phoebus cartel? Prior to 1921, light globes were actually considered to be part of capital equipment- you purchased a light globe once under the assumption that it would last for many, many years. The manufacturers worked out that if they introduced planned obsolescence (max life span of 1000 hours) they would be able to sell a heck of a lot more globes! Call me a grumpy old conspiracy theorist, but I wouldn't be surprised in the slightest if this 'failure' was simply another step by manufacturers to ensure the continued flow of that sweet, sweet globe money.blogzilly said:SNIP
So I looked it up. Apparently the bulbs can have something in them fail and the UV output can increase.
