"Microwave pumped"[edit]

Moved from list of Electric light technologies in that article:

  • microwave pumped [?]

(Some lasers are pumped with electromagnetic radiation, and there are blue-sky proposals for beaming microwaves as a means of power distribution. This could have something to do with either of those.)

The line went from

Microwave pumped

to the form above in its first year, and has seen no further change in over 9 months. Moving it here does no harm, since it conveys no information and since it is not about a currently practical technology; it helps by dispelling both confusion, and readers' anxiety that they may be ignorant.

If someone wants to write or find even a stub article on the subject, that would give it some context, the line may be the start of something deserving space in the article. --Jerzy 23:11, 2003 Dec 9 (UTC)

Whatever is this supposed to mean?[edit]

"The total amount of artificial light is sufficient for cities to be easily visible at night from the air, and from space. This wasted light should not be confused with the light pollution that burdens astronomers and others, although it is the source of it." It is the cause of light pollution — so how can it be further confused with it? Njál 19:59, 10 December 2006 (UTC)


It took me quite some time to find what it means to have higher than 100% efficiency in the table, should there be more information about that in this article or at least linked to the correct portion of the efficiency article so it is easier to understand?

Consensus building[edit]

Did only ONE editor find the article title ambiguous? Usually we discuss moves. --Wtshymanski (talk) 15:48, 25 April 2010 (UTC) One song by a rock band, and one poetry collection, needs disambiguation? forsooth. --Wtshymanski (talk) 15:49, 25 April 2010 (UTC)

Yeah, looks like this was a good-faith move to make room for a page (Electric Light (poetry)) created by the mover a day or so ago. I propose we move the current Electric light to Electric light (disambiguation) and move the obviously primary topic back, with a hatnote to the disambig. (It may also be worth pointing this redirect to the new disambig page, since there are now two Electric capital-L Light articles.) --JaGatalk 15:34, 26 April 2010 (UTC)

No history?[edit]

Are you kidding? No History section on the article on Electric Light? I know there's one on the article on the lightbulb, but cmon. Gaiacarra (talk) 16:28, 5 November 2011 (UTC)

Lamp life expectancy[edit]

It is a complete myth that the life of a filament lamp is shortened due to frequent power cycling. Contrast the compact fluoresent lamp where the 10,000 hour life assumes the lamp is operated under laboratory conditions. Frequent switching vastly shortens the life, often to less than the 1000 hour life of the filament bulb it usually replaces. (talk) 16:54, 24 August 2012 (UTC)

When the filament is cold, its resistance is lower, therefore a higher flows through it (until it has heated up to normal operating temperature). So during that brief moment, the power and therefore the stress on the filament is higher. That in turn makes premature failure more likely. Noggo (talk) 17:34, 7 November 2013 (UTC)
