Talk:Cold cathode

message: Is a neon lamp really an example of arc discharge? I thought it was glow discharge. A neon sign, on the other hand...

thread_title:  Arc or glow discharge? 

message: Right now, if one searches for "cold cathode" in Google, one gets a whole bunch of ads for the PC case mods using "cold cathodes", and mostly after those, comes more generic items.  I'd love to see a "Common Usage" section, with at least one question answered: what sort of power supplies are really required?  The case mods are all being sold with inverters, which convert from PC power supply input (12VDC, approx. 4W per tube) to (I think, based on some blogosphere statements only) ~300 VAC at some unknown Hz and low current.  If this is true, I think it should theoretically be possible to build an AC-to-AC power supply cheaper than those inverters, losing less power to heat in power conversion, and very useful to implement those wonderfully inexpensive cathodes for room and desk lighting and more.  Anyone have a clue where to look for the skinny?
:Wikipedia isn't the place for manuals or how-to documents, sorry. See Wikipedia:What_Wikipedia_is_not#Wikipedia_is_not_a_manual.2C_guidebook.2C_textbook.2C_or_scientific_journal for some suggestions (and maybe someone can beautify this link, as I don't have the patience to figure out whether it can be, bleah). 72.48.98.26 (talk) 09:36, 17 September 2009 (UTC)
replies: text: Regarding your question "what sort of power supplies are required" I added an external link to Everbrite.  This is one of several companies who make neon lamp supplies.  Hope this helps.  WWriter (talk) 19:49, 28 March 2011 (UTC)

thread_title:  Weird... 

message: The wording in the "details" section is highly technical. I have a degree in Computer Science with some experience in electrical engineering and am generally well-rounded technically. Even so, I'm having a hard time figuring out what this section is talking about and why it's important. I think this should be reworded. If you look at one of the pages on one of the reference sites, you can see that it's much clearer and easier to understand: http://www.solelighting.com/node/8
Also, it looks like one of the references is just some company's product page, with no real information on it: http://www.egl-lighting.com/products.html I find that highly suspect and think it should be removed. 209.134.115.80 (talk) 00:31, 24 May 2011 (UTC)
replies: text: 2015 - still needs work. Perhaps should be renamed to cold cathode device with 'cold cathode' being just a disambiguation. - Much better if all CCFL content moved to a CCFL article ? - Rod57 (talk) 19:05, 28 September 2015 (UTC)

message: How low is too low when dimming the backlight? For example, if I set the brightness of my LCD monitor to 25%, will that increase or decrease the lifetime of its CCFL backlight? SEppley (talk) 17:54, 7 October 2011 (UTC)

message: Hello fellow Wikipedians,
I have just added archive links to  on Cold cathode. Please take a moment to review my edit. If necessary, add  after the link to keep me from modifying it. Alternatively, you can add  to keep me off the page altogether. I made the following changes:
*Added archive https://web.archive.org/20101026042259/http://www.egl-lighting.com:80/products.html to http://www.egl-lighting.com/products.html
When you have finished reviewing my changes, please set the checked parameter below to true to let others know.
Cheers. —cyberbot IITalk to my owner:Online 08:04, 30 August 2015 (UTC)

thread_title:   [[cold-cathode fluorescent lamp]] needs its own article 

message: A negatively charged electrode emits electrons or is the positively charged terminal  A negative electrode emits electrons into the device, into the vacuum in a vacuum tube. It is, then, the positive electrode in a rectifier. That is, in a power supply the cathode connects to the positive terminal of the output (where electrons come back in).  The terminology is even more confusing in batteries and electrolysis.  Gah4 (talk) 22:47, 9 September 2016 (UTC)
