Very n00b question about led

[beeflolo]

So sorry about the n00b question. When it comes to conversion, my brain freezes.

To make this simply, heres what i want to do....

I want to take this led bulb (Besthongkong - Eastern LED Source Shop: Loose LED, High Power LED, Car Auto LED, LED Light Bulbs, LED Strips, LED Flashlight, LED Module 100mA 10mm High Power White 10mm LED 55 Degree) and put it on a 12V line by itself. It will not daisy chain to another led bulb. What resistor do i need to MAXIMIZE its brightness. 100ohm or the 470ohm.

My goal is to replace my landscape low voltage bulb with these. Possible?

the specs of the bulb...
High Power 20-100mA 5 chips White 10mm LED

* Vf: Typ 3.3V
* Iv: 10000-18000mcd @ 100mA, Total power 825,000mcd*
* Iv: 20lm @ 100mA Max, 1W power ~53lm*
* Viewing Angle: 55 Degree
* Color : Pure White
* Super Reliable LED, 14 MIL chips.

Many thxs!!!
