any one else upgraded these

got me some of these leds http://www.ledrise.com/leds/5mm-leds/p441/nichia-5mm-white-led-44000mcd-15-20ma-nspw500gs-k1-w-b1-b2/

and put them in some of the cheap light from DX http://img.dxcdn.com/productimages/sku_0824_1.jpg

the result is very impressive for a keychain light

Nice find! You upgraded keyring “22000 mcd” lights from DX or a bigger multi led 3xAAA flashlight?

these ones my Friend http://www.dealextreme.com/p/white-flashlight-keychain-22000mcd-10-pack-1100

Yes, very impressive. I think I got one of those super 5mm LED's or something like it by accident. See post 14 of this thread.

Perfect, thank you!

Someone else did it with 3 and filmed it. Its a poor video but worth a look here.
