What is the footprint of 1000 watt HPS?

When I run them close it withers the fan leaves.

i got this girl and her top bud is 16" from the light View attachment 2069773in the sweet spot directly below the bulb and it looks like its being scotched. View attachment 2069771 As compared to all the other buds that looks like this View attachment 2069772 Im sure its not a good thing and i am thinking about moving the light up to get more coverage. By moving the light up to get more coverage it will cause me to lose some penetration. Why is getting good penetration important since only the top buds are the ones with good quality? I took another pic of under the canopy of the plant with the scortched bud and it is 42" from the soil to the bulb. So im guessing that 6" on the bottom of the plant arent getting the proper lighting since it is out of the 36" rangeView attachment 2069820

if you have a big hood like a xxl or a raptor a 4x4. a smaller hood id say 3x3

besides the chart in Q? is supposed to be temp based so ..... operating ambient temp decides distance from light to plant and reflector choice actually decides that and those calculations are based on open para style i also set my room up by that chart and many others.
