LEDs draw as much current as they are allowed. If they draw enough, they will illuminate. Generally the more current they draw the brighter they get. At a certain point in the consumption curve they will get very bright and then progressively dimmer. The more over-current allowed to flow, the faster they become dimmer. I've seen LED act light a single-use flash bulb (you weren't around when those were all the rage).
You don't have to use a resistor to limit the current drawn by an LED, but that is the most common way. You can also drive them with a Pulse Width Modulator, or a constant current source, or many other ways.
Finally, the package the LED comes in makes DIDDLY SQUAT difference how much current it draws. A surface mount LED draws no more or less current than the same device packaged in a 3 mm, 5mm, 10 mm, 45 inch, or any other package. The size of the size and composition of the substrate and doping material make the biggest difference in how much current the LED will require for maximum rated brightness.
