Connecting LED with external power

I believe I mentioned LED current in post #2. Yes, I was aware a LED is a current driven device. The link for the LED in question merely tells us it's a 3.3 volt 1.0 watt LED. Actually looking back all the link mentions is:

Brand Zerodis
Light type LED
Special feature energy_efficient
Wattage 1 watts
Light colour Cool White
Unit count 50 count
Colour temperature 6500 Kelvin
Number of Items 1

Not even sure where the Vfwd of 3.3 volts actually came from? Other than:
