Ernie,
You'll probably have better luck at the lower levels if you start the ramp at or just below the forward junction voltage of the LED's. Otherwise, you'll have an apparent delay while the voltage ramps up from zero. LED light output vs current is relatively linear. Fortunately, if you are operating in the DC domain, you won't need to deal with crazy intensity "snap" issues associated with some phase control designs.
