Vf 3 4v forward current. For a 3 watt led it s approximately 2 38 watts. So we consider 3 4volts as optimal voltage and thus the 1 watt led is running at 3 4 0 3 1 02 watts.
For a 3 watt led it s approximately 2 38 watts.
230v led driver circuit principle. Here is a transformer less 220v led circuit not very efficient but very simple and quick. So there s several. 230v led driver circuit principle.
