I don't really trust the published numbers from the mfg. Instead I check for actual par readout at different heights to insure propper distance.
search the play store for ppfd meter, I use this to get a baseline par reading. I use 400 seedling 600 veg and 900 flower. Also research your light to see what you find regarding true wattage/ power draw. This all together will be the true values of your light and not the numbers someone came up with to sell the light.
I use a ppfd meter ( par ) from google playstore, search ppfd meter. I use it for a baseline. Not sure how accurate it is but it is working for me. 400 pfd seedlings, 600 veg and 900 flower.
I don't see any PAR numbers in the pics you've included. Can you ask the manufacturer for a PAR chart? Also ask them what their recommended light distance is for each stage of the plant's life. Honestly, the manufacturer should know what's best.
Can you download the pic and post it? I cannot. an 800 watt light is powerful- that said I would start higher and read your plant response as that will supersede any meter reading. Dial it down power wise for sure and don’t start at full- look for leaf taco-ing before they brown on the tips-
dam my brother bought one too he has the pamphlet and he lost it so I'm going to get him to look for it. Thank you I will definitely take your advice go up higher and play with the dimmer

Who is the manufacture? Do they have a chart on their site?
