Is there such a thing as too many lumens?

Lets say i'm growing plants and the tops of the plants are 14 to 17 inches from the glass shield of a 1000 watt HPS. I can keep the temperate at 14 inches from the glass shield of the light at 80F or lower it down to 75F or even down to 72F and keep 40-50% humidity, light on.

I have read somewhere that there can literally be too many lumens for the plant to handle despite good climate conditions. Based on your experience can this be a problem?

This is during fruiting of the plant and due to setup the light is as high up as it can go upward, plant(s) is tied down to keep it from getting too close to the light, plant could possibly be further tied down lower. Ty in advance for your response.

You could see some bleaching from a 1000w that close. Your leaves will turn a very light green, almost white. Try not to let them get any closer than 14"
