SAD lights are used at distance of 1-2 ft to get that brightness.
Your bulbs are probably 1100 lumen. Lumen and lux are different. Specifying lux requires specifying the distance or area. 8800 lumen on ceiling would be more like 800 lux at normal distance. Which is a bright room but not sunlight bright which is needed for SAD.
