HLG Scorpion Rspec 600w

So I got a little crazy a few weeks ago and got the HLG Scorpion Rspec 600w. Problem is that I am new to all of these and have no idea how to use it properly and its hard to find info on it.

I am mainly using the light to transition from veg into flower. Its in a 5x5 tent and will be in Veg for two weeks then flipped to flower.

So question is…how far above canopy in veg at what intensity?? and then same for flower??

I run HLG 260s at 2 feet above the canopy.

How close is too close? If you can feel the heat from the light on the back of your hand when it is held at canopy level, then it is too close.
