Hydofe 240w light

After about 8hours the bloom mode dosen't work any more the other settings do.How important is the mode some lights don't even have it?

Bloom switches on those cheap blurple lights turn on the red diodes. I’m not familiar with hydofe, but if it has a bloom switch that’s probably what these are. Red diodes are good for stimulating flowering. You will have both less light and less of the more desirable light for flower. It matters, but I can’t quantify the impact.
