Just make sure some internod development occurs (the distance of stem between nodes). Make sure as you ramp up power you don't stunt it. You can't force feed it.
How far away and how much power.. You can save some watts by keeping the light very close and dimmed more than usual -- if the light is covering a smaller footprint than normal, which is often the case with seedligns. Though it looks like you have a small plant in a large pot, so that may not be true here if there is more than 1 pot.
As they grow out, you raise plant to a more orthodox hanging distance to cover more area, and that requires more power. Take some notes about timing and power levels, regardless of what you choose to do. Your local climate and atmospheric CO2 will make for different levels of light a plant can handle per day. It's a little different for everyone, so trial and error is invovled. The development of the internode is your guide.
