What does "LED blinking frequency: .25 Hz" mean?
I'm looking for an LED that slowly pulsate and I may have found one but in it's description, it says that the Blinking Frequency is .25Hz... Is that how fast it blinks? Or how bright it gets? Etc...? It would be greatly appreciated if someone knew and could tell me. Thanks everyone.

If this clears up some confusion... I would like a 5mm red LED that slowly pulsates like this: http://www.youtube.com/watch?v=IXs3uPFu8Io&feature=youtube_gdata that would be the perfect LED. (I'm making a Silent Hill Homecoming controller and the LED goes in the guide button, which I will convert to look like a tri-circle save point that you find in the game =] )

1 Hz means it blinks one time per second. So .25 would be once every 4 seconds and 2Hz would be twice a second.
-
Hz = rate or cycles/second
-
It ins't a measure of brightness, since hertz literally means "# of times per second". It's either frequency of the light wave or number of times it blinks, which if you are searching for a blinking light I would say the latter.

Well, there was another catalog of flashing LEDs that said 2.4Hz was faster than the .25Hz. So would that mean that the .25Hz will be calmer? I hope so... I only need one LED so we'll give it a shot! Thanks! =]

I think that means it blinks once every four seconds. Don't quote me on that though. Physics isn't my forte. I'm a Law/Poli Sci/History major. (yes, I'm triple majoring)

Frequency is measured in Hertz (Hz). 1Hz is a normal steady fequency. 2Hz is double that amount, i.e. slower. Anything less than 1 is faster..right? Damn, I can't remember my physics
