Glare zones

For horizontal task vision (seated, eyes downward for reading), a diffuser output emphasizing this range would minimize both direct and reflected glare discomfort:
0-45 degrees
30-60 degrees
45-85 degrees
Answer30-60degrees. Most vision of this type takes place from 20-40degrees from vertical. 0-45deg. is the reflected glare zone and 45-85deg. is the direct glare zone.

Calculate Luminance

A typical 60-watt standard frosted incandescent bulb outputs 890 lumens for an efficacy ratio of about 15 lumens per watt. As an A19, its shape is spherical. What is the its calculated luminance? A. 25,115 cd/in² B. 25.115 cd/ft² C. 25,115 cd/m² D. Indeterminate, missing variable. Answer If 1 candela (cd) = 4 ∏ lumens (lm), 890 x 1cd/4∏ = 71 cd, A19 = 19/8 = 2.375 in or 60mm diameter (= 30mm radius), L = intensity / projected area, 71 cd / ∏ r² = 71/ 3.14 x (.03m)² = 25,115 cd/m² ARE 4.0 exam prep: BS
