Any old camera (digital or not) has a light meter built in which will
give you the accuracy you need.

Just set a fixed aperture that puts the shutter speed at 1/60 sec
(aperture priority mode).  Install the reflector and measure again.   A
shutter speed of 1/120 sec would indicate the light output has doubled.
