Hello,
Recent advances in LED technology mean its now easier to get the forward voltages of batches of LEDs very similar. Thus the LEDs can be placed in parallel, as long as thermal coupling is good.
Since the switch mode drivers for LEDs in parallel can be made much cheaper then those drivers for long series chains of LEDs, you generally get more value for money with parallel LEDs.
So do you know of off-the-shelf LED luminaires which contain parallel LEDs? I wish to buy them.
(-I am referring to LEDs in parallel but with no series resistors.....these now not being needed with modern, equal Vf LEDs)
