okay I looked up your light for you.. It's French so little harder to find info.. Keep your light 3 feet above your canopy and then lower to 2 feet canopy for flower, This is good light output levels and should not be too much light. You have a nice light there it's just intense and bright and needs to be kept fairly high..
