I assume you mean the Backlight Current since the LCD module itself is less than 1mA... I run them between about 5mA (what I consider the minimum acceptable Backlight level) and 40mA (what I consider seriously bright). The example jpeg I posted is running at 22mA.
There is a spin-off here if you're clever... that super-white LED throws out a considerable amount of collateral light at the right-hand edge of the LCD module. I tend to put my control push-buttons at that right-hand edge. If you specify the correct material for your panel overlay and get your artwork right, you end up backlighting your control buttons for free. See appended jpeg...
