19. A lighting load control device comprising:
a memory storing a day/night light level threshold, a day color setting, a night color setting, and at least one dimming curve represented by a relationship between light level readings and intensity levels, wherein the at least one dimming curve is determined using a minimum intensity setting input and a maximum intensity setting input;
at least one button associated with at least one LED;
a light sensor adapted to detect light and output light level readings; and
a controller that:
drives the at least one LED at the night color setting when the received light level reading is below the day/night light level threshold;
drives the at least one LED at the day color setting when the received light level reading is above the day/night light level threshold; and
drives the at least one LED at an intensity level determined using a light level reading received from the light sensor and the at least one dimming curve.
