7. Photobio safety shall conform to CNS 15592 “No Risk Level” category.
8. The upward beam ratio of suspended luminaire with an upward light output shall be between 7% and 14% after calculation according to the following formula.
Upward beam ratio = (Upward luminous flux (above 90°))/(Total output luminous flux) × 100%

(IV) Special requirements
Regarding energy saving labeling for grille lamps and flat panel lamps: the manufacturer shall conform to one of the following special requirements:
1. The first group of special requirements is the unified glare index and light type and shall conform to the following requirements:
(1) The measured unified glare index (rounded to the nearest tenth): less than 19.0.
(2) Light type:
A. In Fig. 1, reference axis of the plane from C=0° to C=180° shall pass through the center point of luminaire’s illuminating surface and perpendicular to its illuminating surface; the light intensity at right angle 0°of the reference axis is 65-85% of the maximum light intensity of the plane.
B. In Fig. 1, the C=0° to C=180° plane, its angle of 50% maximum light intensity Ɵ1 and Ɵ2 are both above 38° and their sum above 80°.
C. In Fig. 2, the cumulative luminous flux in 80° of the reference axis solid angle is above 80% of the total luminous flux except those with upward light output. Round the measured luminous flux to the nearest tenth.
2. The second special requirements are the distance-height ratio and the average brightness, which shall conform to the following requirements:
