You will be undervolting the LED by .3V, but otherwise it should work ok. Note the LED will not be quite as bright as it would be with 4V, but 0.3V isn't much to worry about. Also, make sure the adapter has the current capacity for the LEDs. If the LED draws more current than the supply can put out, it will not work and may burn up the adapter.
