Photocells need some calibration to be responsive in the exact lighting scenario you have. They can be used to detect large or small fluctuations in light levels to distinguish between one light bulb and two, direct sunlight and total darkness, or anything in between.

so I bought a pack of cadmium sulfide photocells. want to use them to control motor speed based on light intensity.

A battery or other voltage source connected to the electrodes sets up a current even in the absence of light; when light strikes the semiconductor section of the photocell, the current in the circuit increases by an amount proportional to the intensity of Photocells in such devices are popularly known as electric eyes.

This makes LEDs pretty monochromatic and emitters of a narrow band of light. To detect an LED you need a sensor that will be sensitive to similar wavelengths. Photocells are the most common as they detect all visible light.
