Putting 5 volts on a LED

I have a couple of LED's installed but when used with a resistor the light intensity is not that good (ultrabright LEDs). If I loose the resistor and hook it up to 5 volts it's great (and so far working). I guess I'm just drastically reducing the lifespan of the LED. Anyone a clue how long they will hold this way? Or of any other consequence?

Thanks!

Thanks! Great read on the

Thanks! Great read on the LED’s. Well back in go the resistors. I’m using 470R ones and run one from each output channel on the motor controller. Outputs are standard digital logic ones (5 volt with 25mA as an absolute limit according to the manual).
