I'm a bit green when it comes to LEDs so bare with me on this please. Should these LEDs be suitable to do a straight swap with the activity/power LEDs on the front of my case? Am I going to have to get a multimeter from somewhere to find out? Ta
They should be fine, if you can get a multimeter (there less than a fiver from ebay/maplin) get one, see how much voltage you get from the header pins on your motherboard, the ones where you usualy plug the power led's for the case in, if its more than 3.3v you'll need a resistor in line.
The resistors are already fitted to the motherboard, usually sized to give about 10-15mA to a standard 2V LED (red, green or orange), so your white (or a blue) will get a bit less, but still plenty to give a good shine. A straight swap will work. You won't get 6,000Mcd Mega-bright, but you should be able to use the PC without sunglasses on.
Ok cool, thanks for the replies, I'm not after mega bright, a subtle glow is much more my style so that should be a-ok. Cheers again.
