YLXD41YL

Hi, i just bought the YLXD41YL ceiling light.
I am aware that at full max brightness i am consuming
28watt power consumption. If i were to bring the brightness to 1%, what is the eatimate power consumption i will be using? Alsojust to add, the 1% brightness is too strong and glaring. Any way i can make it dimmer?i do think that only 1% moonlight setting, that the light is dim enough. Even when i customise my light to switch on at 1% using nightmode for my wake up morning light, it is too bright. Please help
