How bright should the light be?

[Jjjmm56]

I’m going into flower and was wondering how bright I should keep the light? Also what is the best color of light. My light goes from a blueish to red in color

The blue spectrum is typically used in the veg stage. Flowering is usually done with the red spectrum

Some info on your light will help others to give ya a suggestion for the light height.
