I asked about current, not voltage. Do you know what the I-V curve of a diode looks like?
If you don't have a way of controlling the current, you can easily end up overstressing the LEDs and burning them out. A simple series resistor is usually good enough, but a fancy constant-current source circuit will keep the brightness much more consistent.
