  1. 1. When comparing color temperature efficiency, you are analyzing the sensitivity of the eye to the light spectrum. This is correct if the light source shines directly into the eye. In reality, the light source shines into the environment where the light is absorbed and reflected. The blue spectrum is more sensitive to the eye, but is more strongly absorbed by moisture such as fog and coated surfaces. The degree of reflection of blue light decreases faster with increasing moisture than the eye's sensitivity increases. 2. When designing luminaires, you need to consider not only light to the sky, but also light to the eye. LEDs are a point source of high intensity light. If there is contact between the LEDs and the eyes, the pupil of the eye narrows and the sensitivity of the eyes drops significantly. As a result, you see poorly in bright light. Conclusion: When evaluating the effectiveness of a flashlight, you need to consider the efficiency of the device, eye sensitivity, the degree of light reflection, and eye glare/pupil constriction.
