ok i was lookin at this rad instructable which made me sart thinking if only my camera can see IR light then what if I got a super strong IR led (or alot of them) then I searched and found this which said to buy this from radio shack which made me search for high output IR leds I found this (the one at the bottom look strongest) but I did'nt know if my camera would pick it up

Please help me out here I don't know much about IR if you know what kind I should get (I'm looking for the strongest kind, or just whatever will work best) please find it on amazon or whatever

Sorry, but I have to say everyone has the wrong idea.  My website gives instructions on how to make an infrared light  you need a halogen type flashlight like a maglite, and an 800nm infrared pass filter taped onto the front of the flashlight,, that will give you about 150 to 200 feet or range

The LEDs will give you about 10 to 30 feet, a circut board already set up can be bought on ebay for $5 from hongkong and it takes 12v power and has 24 LEDs

Try one of these from BG Micro (one of the good mail order electronics suppliers.) Also available assembled and tested for a few dollars more, and in a larger configuration.

HI Westfw: I just want to thank you for linking this site. I have been looking for something like this for months and never had any luck. the prices are GREAT and I cant wait till I get my IR night vision setup for my CamCorder..Thanks Again!
ultra cheap and inefficient solution i'd try - electrical red hot heating element or high watt incandescent lamp dimmed exactly to the point where it does not make visible light is it gonna work ?
Probably not. The frequencies of light that a CCD or other silicon sensor is sensitive to are relatively close to the "red" end of the infrared spectrum, while the frequencies emitted by "hot" things is at the other end of the infrared spectrum. Won't hurt to try, though. You can point your camera at the stove and see if the elements look particularly bright. You still have the "incandescents are really inefficient", since they'll be emitting all sorts of frequencies that the camera ISN'T sensitive to as well. The nice thing about IR LEDs is that the frequencies emitted are quite close to the "most sensitive" IR region of sensor sensitivity. I think...

Fairchild 880nm, 20deg beam IRED is on DigiKey catalog page 2053.
I'd recommend Fairchilds QED223, Datasheet Here. Just $0.42 each @ Digikey...

DigiKey has a good selection of IRED's. You can buy IRED's @ 880nm from 16 to 27mW/sr with a 20deg beam angle. They are just $0.38 to $0.42 each. I bought a couple hundred a few years back to build IR illuminator 'panels' and arrays. Also have placed clusters at 10 yard intervals in the back yard so I know what range I'm firing at when predators sneak into our yard (coyotes love tasty kittie kats...). I ran ~700ft of plenum rated CAT5 cable all back to the control hub. Each cluster has a dimmed visible red LED in the center for use without the NVG's (night vision goggles). Pretty cool setup. IRED's are really fun.

I used to confuse the heck out of my fellow soldiers when out in the field by making IRED 'throwies' and placing them on the perimeter. I'd tape some to low shrubs that swayed with the desert winds (@ Yakima Firing Center, Yakima, WA) and point out the 'possible threat' to a buddy or even an officer. What fun! They'd don their NOD's and go off to investigate only to be suckered!

Mouser has great prices too, no minimum order.
Digikey has done away w/ their $25 minimum order policy, thanks Digi!
Have fun All,

i suggest buying them from a real electronics supply store were you can get them for about 20 cents each...but you would need alot of them for your camera to really pick up..

what store? What should I ask for?

the one the bottom only has a spread of about 10 degrees, I don't think that's a good idea for nightvision, I would get the first one on that page
