Talk:Centennial Light

message: Is the bulb located in Livermore or Pleasanton?  They are two separate cities, so the bulb can only be located in one of them. - Walkiped (T | C) 20:58, 14 December 2006 (UTC)
replies: text: According to this source, the bulb is located in Livermore.  Any objection to me editing the article accordingly? - Walkiped (T | C) 22:32, 14 December 2006 (UTC)
thread_title: Where is the bulb currently located?

message: I just received a message from the bulb's webmaster giving permission to use pictures on the site and a few corrections that need to be made to the article. --The_stuart 23:01, 19 December 2006 (UTC)

message: Shouldn't Thomas Pynchon's fictional immortal bulb "Byron", protagonist of "The Story of Byron the Bulb" in Gravity's Rainbow, be mentioned here? --ScottMainwaring 02:08, 20 December 2006 (UTC)
thread_title:  Byron the Bulb 

message: Has the bulb's input power ever been measured?  It is typically quoted to be 3 - 4 watts.  But, based on old catalogs, the bulb appears to be Shelby's 30 watt model.
Some possibilities are:
1) They are cheating by dimming the bulb.
2) The bulb has reduced its power by itself over the years due to wear and tear.
3) It's current brightness equals that of a modern 4 watt night light, regardless of actual wattage.

message: Why is this being portrayed as factual when there is no reasonable evidence to support the claim that this bulb has lasted over a century? Looks like a hoax to me. Pw33n 02:41, 3 May 2007 (UTC)
replies: text: I can assure you that I have seen several nationally televised news stories about the light bulb. That's how I heard about it and looked up this article. There are plenty of credible references in the article to prove that it is not a hoax. Royalbroil 02:49, 3 May 2007 (UTC)
replies: text: That'd be like a "super-hoax," I heard about this thing years ago. IvoShandor 09:25, 16 May 2007 (UTC)

thread_title:  Good article review 

message: Is there any research being done to try to maximize the life of modern bulbs based on this, apparently better, old technology?  —Preceding unsigned comment added by 173.11.36.169 (talk) 19:51, 1 May 2009 (UTC)
replies: text: From the article itself, it doesn't seem that the bulb or its making possess any special qualities. The only factors that are claimed to contribute to the bulb's long life is that A) it's a low power bulb, and B) it's been on almost continuous use.  —Preceding unsigned comment added by 201.210.42.13 (talk) 14:51, 23 July 2009 (UTC)
replies: text: Also one major factor is that it has a very thick filament; so it is very unlikely to burn through, but also has a very poor efficiency. Nothing we'd want today ;) --91.89.83.185 (talk) 20:40, 14 October 2009 (UTC)
thread_title:  Fact Request 

message: Curiously, there is no mention of the light output (luminous flux) of the bulb. Surely that would be an interesting fact, so that we could compare this bulb's luminous efficacy to other light sources (such as regular commercial light bulbs run at nominal voltage). Can anyone locate a source which would mention this? --Jmk (talk) 11:19, 15 June 2011 (UTC)

message: According to [], the lamp once consumed 60 watts, so it should have been much lighter then. --46.21.6.140 (talk) 14:15, 19 April 2013 (UTC)
replies: text: The efficiency of bulbs decreases with age.  It most likely still consumes 60 watts and only emits 4 watts of light.  On the other hand it could be increasing its internal resistance3 and so only allowing 4 watts to pass through.  Incandescent bulbs are not very efficient, being used mainly for their very high light quality, broad spectrum, and continuous output in contrast to other bulbs like LED which are partial spectrum and usually have a very noticeable pulse rate to some people, particularly individuals with medical conditions like nystagmus. 23.236.23.78 (talk) 22:47, 29 August 2022 (UTC)
thread_title:  4 watts once have been 60 

message: There was a change made to the lead to replace "burning" with "on". I reverted it, but accidentally hit enter before I could write my whole summary. I was going to say, "but 'on' didn't mean 'powered on' to me at first read". Chris857 (talk) 13:08, 24 April 2018 (UTC)
thread_title:  "burning" 

message: It appears the Centennial Light is about the same age as the oldest living person, 117-year-old Chiyo Miyako of Japan, born 2 May 1901. I don't know if this piece of trivia is notable enough to be mentioned.  — Preceding unsigned comment added by 170.199.135.213 (talk) 22:40, 13 May 2018 (UTC)
