 |  |  | Black Light Flashlight?
< on 1/8/2004 7:14 AM >
|  | | | I was thinking if you can find one it might be of real use.
It gives off ok light and does not kill your night vis.
Any one know where I might pick one up?

I think you can get small battery powered blacklights, but I dont' see how that would be very useful. Unless your target has luminescent walls you won't be able to see much. A red flashlight lens or red LED light would be better for protecting night vision.
Turn off the internet and go play outside.

I assume you mean an UV lamp?
Bad idea. Really.
While they do put out a tiny amount of high wavelength visible light, 99% or more of their emitted energy (we're taking usually a couple watts, here) is in the form of ultraviolet radiation. A little 3- or 5-watt portable UV source is really not a wonderful thing to be using for long periods without eye protection, or so I've been told.
Just use a flashlight with a red lens like everybody else, eh?
If you insist, though, there are usually some cheap ones on eBay, and most serious science/rockhound type places sell nicer ones for field identification of minerals... or spotting scorpions, I suppose.
Apologies if you meant something else entirely.

| | | | I always suspected that black lights are actually worse for night vision, because some of the invisible UV triggers pupil constriction. Just speculation based on experience, no idea if its true.

Indeed, I've suffered severe UV burn on my corneas twice. It was the most excruciating pain I've ever felt. Cocaine and Demerol did little to help the pain (both administered by the ER docs of course  )

No; no snorting. Like I said, I had severe UV burn on my corneas so they instilled cocaine (I think it's was 1%, but I was blind at the time) solution.
It's a very useful drug despite what you learned in D.A.R.E.

| | | | So your're saying eye drops right? That's what I thought, I just thought it would help the others better understand.
...enough off topic, I don't think that a black light flashlight would be very useful and you'r best bet would be a red filter as others have said.

|  | | | Instead of using blacklight, why not just by an IR illuminator. I am assuming here that you want the black light to make your NV brighter. An IR illuminator would just clip on to your NV headset, and make everything that bit brighter when you look through your NV.
But if you are talking about a light with a black filter, then I'd suggest a dark red filter instead. Because red light travels the slowest, it will dissapate quickest, meaning it will not be bright to someone about 20 or so meters away, and won't be obvious to someone who is closer. Which is why streetlights are amber, it's a compromise between the bright light of a white bulb, and the slow travelling red.

| | | | You're both wrong, but Chikote more so. A physics class would be good. No offense meant, Shane.
The usefullness of red light isn't because it travels slower, because it doesn't. Here's a nice page for you: http://www.flashlightavenue.com/colorguide.html

| | | | Well, unless Chikote is travelling at some disgustingly fast rate of speed, the light coming off of his flashlight would be traveling at pretty much the same speed as the light coming out of my flashlight standing still. It was a quick generalization, and what I really meant to say was that the color of the light does not affect it's speed in any way.

For those who care. Some specialty pharmacies do carry pure cocaine! It can be used in compounding special elixirs etcetera. Not just your average Shoppers Drug mart would have it, most will have to order it in. I worked in a drug store at one time, that's how I know

| | | | Cocaine is what you call a Schedule II drug, meaning that it has a very high potential for abuse, but does have legitimate medical uses (generally stopping severe nosebleeds (ironically)). Pot, on the other hand, is considered a Schedule I drug, meaning there are no legitimate uses for it. Which just goes to show you that the folks in the FDA must have extremely long and flexible necks to get their heads that far up their asses.

Even if he is traveling wery fast, the light is still going at the same speed, assuming you're both in the same medium (presumably vacuum).
I was indirectly pointing out that the speed of light is constant in a vacuum, but we don't live in a vacuum.
In a vacuum, C is 299,792,458 m/s. In air, however, it travels about 90,000 m/s slower. In ice, it travels about 228,000,000 m/s; in liquid water ~225,000,000 m/s; and about 200,000,000 m/s in glass. Without that fact, lenses wouldn't work, so our eyes and other lensed devices would have to use some sort of reflective parabaloid instead. On the bright side, there would never be heat haze, diamonds wouldn't sparkle, and astronomy would be much easier.
Hey, flashlights use both parabolic reflectors and lenses, so this isn't off topic. I think we can both agree that Chikote was wrong; the speed of light has nothing to do with the use of red light.

| | | | No what I meant was, Red light is less visible to the human eye, or something like that. Red light is the least intense, with blue being the most intense. If you walk around with a red light, it is less noticible than a white light.
That was the point I was trying to make. I wasn't attempting to be particularly clever, and you don't need to try and show off either, it impresses no one.
