How to get the maximum current of LED?

Max voltage level at which LED's operates = 3.3 v.
Max current at which LED's can stand = 45.4 mA.
P = V*I.
P = 45.4*3.3 = 149.82.
It is nearly 150 mW.

These are old things. Now LEDs are available with wattage >10W easily. Philips 22-W led light can be available.
But still, for exam basis, 150mW maybe right :(.

How do we find the max voltage = 5v ?

Max voltage=5V max current=0.3mA(approx)then power=v*i
