Photone app, and readings on the output of lamps

Hello y'all
So I was reading a thread yesterday on different lamp outputs and comparisons of them in regard to price, as well as output in a given tent space. And one of the thread responders and shared a link for the Photone beta app. So I decided to follow the link provided, and downloaded the app for my use to see how I compare with the favored requirements of our loved plants. That said I have 2 HydroCrunch 350100200 lamps. 240w total output when all lamps are powered on.
I know these lamps are less efficient than most of the QB boards and the lamps currently on the market. It was what I could afford, at the time to get me up and running for my first indoor grow in many years.
That said, attached are some screenshots of the tests preform with the app.
Now please let me ask, that with these numbers, I do have a fair amount of good useable light going to my girls in the 4x4 space I have right?
I am asking this because, This is the first real-world example I have seen of what is going on in my tent and what is being given to my plants. I do know I could do better with the choice I made on the lamps, and will more than likely upgrade to better fixtures later, after my experience has increased and my budget does also.
Please be kind, And thank you in advance.

The sensitivity on a light sensor of a phone is night and day different than actually buying the real deal. But if you can’t get one and this is all you got. I guess use it the best you can.
 
You're best off getting a $20 Uni-T Lux meter. Migro has compared to his Apogee PAR meter and the results are within a few percent; actually quite impressive.

The conversion factor was .017 iirc. E.g. 10,000 lux = 170 PAR

The phone apps are ok for measuring relative brightness, but without a calibration reference they're not very accurate for measuring absolute brightness.
 
Best iPhone around still gets sound decibels off too. Micro speakers/mic are different then what the manufacturer uses. And I would assume the same for a light sensor. Essp considering the fact the sensitivity is only meant for when the phone is applied to your face or not

The i phone version appears to be fairly accurate. The Android beta Version is another story, it's totally wacked on my phones, useless.
I'm back to my lux meter.

I believe Photone uses the camera, for that reason.
 
I’ll be giving this a shot with my new iPhone 13 when the lights come on. I was using the ppfd meter app on my galaxy but it’s not super accurate from my understanding. But the Photone with an iphone is supposedly only a few points off apogees
