content: 1 to change the light bulb and to post that the light bulb has been changed.14 to share similar experiences of changing light bulbs and how the light bulb could have been changed differently.7 to caution about the dangers of changing light bulbs.6 to argue over whether it's 'lightbulb' or 'light bulb'Another 6 to condemn those 6 as stupid2 industry professionals to inform the group that the proper term is 'lamp', and not bulb – after all bulbs grow in the ground.15 know-it-alls who claim they were in the industry, and that 'light bulb' is perfectly correct.19 to post that this page is not about light bulbs and to please take this discussion to a light bulb page.11 to defend the posting to this page saying that we all use light bulbs and therefore the posts are relevant on a technical forum.36 to debate which method of changing light bulbs is superior, where to buy the best light bulbs, what brand of light bulbs work best for this technique and what brands are inferior.13 to randomly comment "Me too" to bookmark the thread.5 People to post pics of their own light bulbs.1 person who refuses to purchase light bulbs to finance the capitalist pigs, and so builds his own.15 People to post "I can't see shit" and post the light output specifications for their own light bulbs.7 to post URL's where one can see examples of different light bulbs.4 to post that the URL's were posted incorrectly and then post the corrected URL's.Another 3 to post links to rebuttals for the specifications of the original 7 links.2 to start an argument over whether ES is better than BC.5 to post to the page that they will no longer post because they cannot handle the light bulb controversy.4 to say "Didn't we go through this already a short time ago?".13 to say "Do a search on light bulbs before posting questions about light bulbs".1 to bring politics into the discussion by adding that Winston Peters isn't the brightest bulb.4 more to get into personal attacks over their political views.1 admin to ban the light bulb posters for inserting political discussion and close the thread.Credit possibly to Nelson Snippets Facebook Page.Credit definitely to my wife for stealing it for her geeky husband.(Slightly amended by me.)

content: I find this a bit rash. Forethought is required. It needs at least two pages of H&S discussions before a hand goes anywhere near that light bulb.There are also several pages missing where discussions were based around the fact that we lost our right to choose what sort of bulb we wanted because that choice was removed by the government.

content: Quote from: IanMacdonald on October 28, 2017, 08:47:20 pmDid you make sure you changed the caps first? Those bumble bees and tiny grief caps all are long past their due date at this point. I know nothing about tube electronics but I have watched a video where you need to change the caps: therefore I can diagnose any tube based equipment. So long as its the caps that are the problem ven when the caps are not the problem.Notice how on the internet you pick out the people who have only watched a few videos but think they are experts because of it?The worst at this are medical forums that have a "harm reduction site" for drug users. ALL the info you can learn is actually a collection of old wives tales that have been repeated so many times that people see the argument of authority and therefore it must be true. Few people realize that arguments of authority are actually fallacies. They become "common sense" but are based on others ideas and not self intuition.When there are two contradictions people usually agree with the person with the higher post count or moderator/ oldest join date. They will even argue the point having no more clue then what Wikipedia and forums have to offer.So is a dim bulb when acting as a current limiter acting as a voltage or current controlled device? When you plot the I/V on a graph using the columbs-hertspring-rusle equation you will find they graph exponentially with I following V in the tungsten quartz iodine depletion layer. They call it "doping" for a reason; because being a dope doesn't make you smart.12 people to click on the wrong author to quote then the argue why meant to do it.14 people to yell at their mother through the basement floor while putting other people down for being troll on the internet.85 "hackers" who don't realize that "social engineering" can't be learned from online and that if they could "socially engineer" that they would be good at picking up women.1 to post "FIRST" in a thread2 to post "second" along with another person27 that regularly buy condoms to replace the last ones based on the expiration date.13 to pretend they are a hot chick to get attention14 to post a picture of a person with a large fruit in their rectum

Or a TIG to get really nice welds.For stick welding use the heaviest ga stick you can find at maximum current. Since its a current controlled device. Don't forget to wear a ground strap to protect the part from ESD.A light bulb is really a one element directly heated vacuum tube with a two way back to back diode with a very flat trace on a curve tracer.

Also why are you using a light bulb where you can get a CREE soft white LED light with a CRI of 98, at 5000K, 7 watt 30,000hr long life bulb that fits an Edison style screw plug for the same price? Stupid.Also ever just consider moving into a house without a burnt out light bulb? Think how much this renovation and building permits will cost and time spent vs just selling the house. Stupid.And why are you actively replacing a light bulb with another inferior bulb when you could be using this opportunity to switch to LED or CFL? Stupid.You could repair the bulb unless of course you don't care about wasting money:Heat the base and unglue it from the metalUnsolder wiresMake a pin hole to let the air in using frictionMelt the stem out being sure to anneal the glass evenly on a latheRemove the damaged filament and locate the breakUsing an electron microscope and probes join the filament together and direct high energy electrons at the end spot welding them together.Remelt on the base and evacuate for several hours in an over letting the bulb outgas.Make a gas out of iodine and argon at a ration of 74ppmFill the bulb with an inert gas at 83 torr and seal off the glass evacuation stemResolder leads and glue the glass back into baseSend the unit off the under writer laboratories to get certified as safe for consumer useStamp the top with a seal indicating correct regulatory listingsTest for several hour under different vibrations temps and voltages.Why throw it away when you can easily repair it? Stupid.
