/**
 * Scale the LEDS if you want to keep them from running at maximum current for longevity
 * The Hard LEDs are XTE Royal Blue and can run to 1500mA max
 * The Soft LEDs are XPE Green and can run to 1000mA max
 * The A009-D-V-1000 BuckBlock will provide up to 1000mA
 * For maximum life of the LEDs we should run them around 70% of the max, so we will need to scale the soft LEDs back.
 * Testing indicates that 7 results in .72Amps, which is close enough
 * Both LEDs get a bit unstable at low currents. So a minimum brightness needs to be established. 200 is a good starting point
 * Both LEDs are non linear in output vs current over these ranges, so look into this if we add a dimming function.
