Just checked the lamp in question - took it home for adding to the future annex to the wall of shame. 994 hours which is above the 860 hours the last lamp had a blow out after but given the same condition. A member of the forum Inkie 2 replaced the lamp last month but unfortunately under "reason for replacement"
line on the replacement lamp box tag they have to fill out amongst other lines in me
tracking the lamps, he just wrote in "deformed." Not why he had reason to open up the
fixture and note this trait which I can easily also see such as with a "snowball" lamp, just "deformed" instead of something like dim or brown as description of why this
fixture was not outputting like the others. Not a lot of help in studying or coming up with trends. Still I did
send him an E-Mail about the
fixture to check it for the ____ suspected cause of failure.
On a similar
Mac 2K note, recently did a re-lamping for a tour and a debate came up between my boss and I. Lamps on this tour all are in the 1,200 hour range but some look really good. The tour person was asking if he should take some of these still good lamps and place them into fixtures on the floor and or easily gotten at should they develop problems. My boss in seeing price and random chance was for one position, I was for another out of a specific reason these lamps look good now but would not in the second
fixture - this beyond lamp
tracking problems on my end.
Why did I recommend against attempting to install what seemed perfectly good lamps into other fixtures for a few hundred more hours? This given all were well beyond their expected lamp life but in some conditions could still eek out a few hundred more hours reasonably given a 1,500 hour norm often? What conditions in my
point of view would be necessary to eek out those few hundred more hours? Why would I feel that if installed into different fixtures would such lamps no longer be safe or even live up to a theorized maximum lamp life above what the listed lamp life is? This again given that lamps at 1,200 hours which still look good can often live up to 1,500 or beyond lamp hours. Specific reason for this is requested.
Than of course, in the same respect how can a lamp that looks brown
in one fixture look perfectly fine in another
fixture? This given a lamp under expected lamp life of the lamp, what about a lamp after that expected lamp life in the above would make me not want to put the lamps into new fixtures? This or make me expect that even perfectly fine lamps would not dependably work in the new fixtures in this instance?
