With bright artificial or natural light, mirror model will provide very adequate illumination. However, if light conditions are poor, it is necessary to incline the microscope on its inclination joint for the mirror to catch sufficient light, positioning the inclined eyepiece at a less convenient angle. Therefore, for a poorly lit environment, we recommend selection of 109-L or 109-LED, with electric illuminator.
