Bitspower X-Station LED Power Hub questions

I was wondering if anyone could answer a simple question about the Bitspower X-Station LED Power Hub as I couldn't find any specs from the manufacturer or reseller sites. I'm planning on modding 12 fans with 4 UV LEDs each and I purchased this hub to be able to use a single switch to control the LEDs.

This particular hub has 20 terminals for LEDs with a resistor and 20 terminals for LEDs without. I assume this means that the terminals for the LEDs with a resistor are 12V and for the ones without are 3.3V (as that is the most common LED voltage).

So my question is, is it possible to connect 4 LEDs without resistors in parallel to a single terminal from the 3.3V? As it is, the LEDs in the fans alone total 48 and I'm planning on using additional LEDs throughout the case as well.

Thanks in advance for any insight you can provide.
