Got it. So just a heads up, some companies will give you a PAR diagram like you've posted and then others will show what the spread looks like across the footprint like the below:
Each number represents PAR in PPFD - which is a spot measurement. Some companies avoid posting a PAR chart like this because their light spread is so poor. The above is the PAR chart for the HLG 550 V2.Here's what I've read are good PAR measurements for the different stages of growth:
200-400 PPFD - seedlings, clones, and mother plants.400-600 PPFD - early to late stage vegging cycles.

600-900 PPFD - flowering, fruiting, or budding stage of plants. Hope this helps! Source: https://growace.com/blog/why-is-par-rating-a-big-deal-for-indoor-grow-light-systems/
