Too much light

I have a 650w and 800w led. I hang them as high as I am able and just turn them down, much easier than moving lights. In veg just start low and work your way up, if plants start to stretch between nodes turn it up till they stop a bit at a time. No need for a meter, the plants will tell you. Better to have less light and turn it up rather than too much light. A little stretching will do them no harm.
