Calculating the resistance for a high brightness led beads chip
As you have guessed, such a low resistor value means that any variation in LED Vf, which will happen as it heats up, will translate into a substantial change in current. Since LED forward voltage decreases as they get hotter, more current leads to more current. It might smoke, or it might not, but you'll have to fiddle with it, measure current when hot, try various resistors, etc...
These LEDs are called COB (chip on board) and are driven with AC to DC constant current drivers that set the current and adjust the output voltage accordingly. The power supply you linked is constant voltage, not constant current. The usual voltage for COBs is 36V, yours is 9-12V which is a bit unusual.
So you need a driver like this one, which can output the proper voltage range while regulating current. Although this one is not exactly the one you need since it outputs a bit too much current. Or you could buy a 36V COB instead, there are a zillion drivers for those. Or you could just get a COB downlight which will save you the trouble of having to bolt it on a heat sink and spend 3 hours looking for stuff that costs $2.
Note these &quot;bargain&quot; COBs usually have garbage-tier Color Rendering Index (CRI) suitable for car parks, plus suspicious tint, usually greenish but expect anything except white. If you want advice on good quality LEDs that look good, ask in the comments.
