[edit] Animated GIF image

The animated GIF is certainly interesting, but having it as the first image at the beginning of the article is pretty off-putting when trying to read the text!

Please do not use animated gifs when not requested. It can be dangerous for health, it can trigger seizures for example. This is no-no. And this particular animated gif is extremely annoying. Animate on request, not stop animating on request.
Perhaps you should lock yourself in a closet for the remainder of your life in order to be certain you will not encounter any possible seizure inducing phenomena EVER. Sorry but the entire world is designed around the needs of the 99.999% of the population that does not experience spontaneous seizures at the slightest provocation. Deal with it.--Deglr6328 08:10, 10 November 2005 (UTC)
This isn't so much about its seizure-inducing potential as it's about being able to read the text without continually being distracted by a large flashing animation in the peripheral vision. It's a nice image though, so I moved it to the bottom of the article as a compromise. --c3o 12:06, 10 November 2005 (UTC)

[edit] Spectrum

Here's a question I wish the article answered:

Why is the light white? or, What is the spectrum of the output?

I would have thought that what you'd get would be a mass of spectral lines, as with a neon sign. So something is definitely different, but what? Current, voltage, gas fill? Is the spectrum a thermal spectrum, a mass of spectral lines that add up to white, or some other spectrum entirely?

What gases can be used? (Well, I suppose that in xenon flash lamps, only xenon, but it seems you can do the same with krypton (except the gas is mighty expensive)). --Andrew 08:57, Apr 10, 2005 (UTC)

You do get a mass of lines, but the spectrum of xenon just happens to be pretty broad, with strong peaks in (surprise) red, green, and blue. See.
A flashlamp sould theoretically be made with any of a number of gases, but xenon just happens to have the "white" result :-) .

[edit] Minimum operating voltage

An anonymous editor changed the minimum operating voltage from 100 volts up to 250 volts, and someone else reverted them right back.

I agree with the anonymous editor: I've always found flash lamps operating from something like 250 volts and up (using a voltage doubler from mains voltage in the U.S. and a straight rectifier for 230 vac systems). Even battery systems (as in camera flash units) tend to be 300-voltish.

Has anyone seen any real-world units that operate on 100 volts?

You are probably right. I revert unexplained anon edits TOO easily sometimes.--Deglr6328 22:16, 12 February 2006 (UTC)

[edit] Xenon flash lamp in Color Spectropphotometers

Requesting information on the subject matter of Xenon flash lamp for Color spectrophotometer, as employed by GretagMacbeth, DATACOLOR etc.Information requested as under :

1. Technial specifications of Voltage, Wattage, Amperage etc.

2. Source from where to buy.

3. Any information relevent.

How about searching THE INTERNET.--Deglr6328 16:18, 2 May 2006 (UTC)

[edit] Technical error

The phrase, “a capacitor that is charged to a relatively high voltage” does not make sense. I leave it to someone better versed in electronics to replace it with a phrase that does make sense. -Ahruman 13:49, 5 October 2006 (UTC)

What about that phrase doesn't make sense to you? Capacitors in xenon flash lamp systems are charged to "relatively high voltages", namely, 300 volts to low thousands of volts.

[edit] Discharge Lamp?

Discharge lamp redirects here. Wouldn't it be better if it redirected to Gas-discharge lamp? Bryson430 13:29, 2 August 2007 (UTC)

Worse, I've realised that there's a Discharge Lamp and a Discharge lamp article. I'll try and sort it out. Bryson430 13:31, 2 August 2007 (UTC)
