nobody finger fu@&ed these lamps - too common an expiation stop using it as a coverall, there are other ones such as the excellent ones above. Umm,
super nova, even seen the results of a
filament or ten shoot out the
bulb on an
incandescent or even
halogen lamp as if a bullet hole left melted into the glass, and the other side where the opposing side of the glass puckered due to the pressure being sucked out forming like a “killroy was here” type shape. I'll post if I have a good photos of this and other below conditions.
More important in these cases of say vaporizing of the
filament depositing itself upon the
globe or a
pinch seal hole, what's going on inside of the lamp at the time this happens, and what's the cause of the white frosting like, or purple black, or silver/black
etc coatings? What is the cause of each condition - such concepts are to be aware of in solving problems rather than just replacing a bad lamp. Really cool to see such things, they are interesting to collect but also important to study and learn the cause of. Often beyond the finger touched lamp, or the blackened verses
clear blown
fuse concept as similar to lamps, you can diagnose in your own CSI type of way the cause of a lamp failure and solve problems in learning from the dead lamps. This also including especially lamp bases on bad ones for they often tell a lot.
Also given the photos, what would cause the below puckered
filament gunshot and if I have it, the
PAR 36, DWE lamp that failed in a as if touched type of way but as the capsule inside the lamp thus not touched. This given both the broken in half nature and other lamps within the
fixture have never had that problem. So what in the photo caused the
filament inside a
PAR 36 lamp capsule to sort of blow
thru the glass of the capsule, this within a sealed beam
PAR lamp?
Further questions, I have had an EVR lamp that was no doubt finger fu@&ed, no doubt by my own
hand early in my career, it continued to work even given this. What’s this, the
filament of the lamp encased within the quartz glass of the lamp - really a cool thing screw the
bench focus, it continued working. Anyway with the DWE lamp in the photos, what caused it’s final failure by way of not just
filament encased within the capsule of the lamp and or it’s outer
globe breaking in half? Say which came first, some pressure
release within the lamp’s capsule by way of say an over-heated condition that forced the
filament to stretch
thru the capsule than have a pressure problem of expanding gasses that blew up the outer
PAR lamp, or say the
PAR lamps’s outer part that got say hit first which caused a rapid cooling of the capsule thus a sucking of the
filament towards the cooler area thus melting it’s way
thru the glass?
Chicken or the egg. One concept in some way implies an over heating of the lamp, the other concept implies a lamp while in use struck by something. This could be a very important question - use of the
fixture verses it's sufficiency to cool what is used in it. Thus a CSI type mystery over just a simple what costs like two or three of us going out to lunch and paying for it lamp replacement costs. Gotta remember the human terms, days wage verses a single lamp. It effects in end result your pay by way of what's left in the budget and your being a professional sufficient to look after your own in saving money for your pay raise. This given the squeeky weel gets the oil and I just for the first time ever signed a refund recipt for some lamps. Long story, before now I never knew much about what I got full refunds on for lamps, it was always just absorbed into the budget. New accountant thus new concept in where is this refund for a few hundred dollars coming from? Sent them the
tracking history of the lamps I got a refund on from in this case VeraLite. Lamps were bad within the first few hundred hours. I sent them back for full refund by way of
tracking them and analizing their cause of fault as manufacturer defect. Lamps got that refund after inspection by the manufacturer - all lamps I
send back get a refund, what's the question? Sure, I'll sign for money coming in verses money going out as normal...
This given I had to E-Mail my electrical supplier about more still
Leviton porcelain lamp bases that due to crappy shipping came to me broken and I wanted credit for them. Beyond this, it's getting to be quite the collection of broken lamp bases out of the box, should I
send them back in having saved them for this purpose, or just toss them out?
Note, the
PAR 36 DWE lamp photos are still on my camera at work. Will update with the photos later. Until than, here is a
bit to chew on that should be curious.
