Does and LED's current draw depend on its voltage drop? Answered
I was under the impression that an LED will draw whatever current it can get it's hands on, as my 20w LED (rated for 13.5 - 15.0v and 1500mA) would draw 3A when running off a 15.2v 2A ac adapter.
Now that I've killed the 15.2v adapter, I'm running it off of one of 2 12v AC adapters, either a 1A, or the 2A one, and the draw is always 750mA (under the max possible supply from adapter).
But when running this same test with a 10w 12v LED, the draw is 1A and 2A (max current supplied by each adapter).
Does that mean that an LED draws a current based off its Forward Voltage, or is there something else I'm missing?
