So I did a little experiment today. I use the Photone app with their diffuser that I picked up. I had a privacy screen protector on my iPhone and the protector is tinted for obvious reasons. I found when I used the app with the diffuser and screen protector my readings were 50-100 units lower than without the protector. Just something to keep in mind if relying on the app with a privacy screen protector. Have to calculate for the difference. ---

You’re luck yours even works I bought the light diffuser, I was getting these readings at the recommended for seedling height and intensity ![IMG_7576](https://global.discourse-cdn.com/growingmarijuana/original/4X/b/b/d/bbd8f4c9cbc42a13f12de931273d800a9b396c57.jpeg) ![IMG_7528](https://global.discourse-cdn.com/growingmarijuana/original/4X/9/e/b/9eb897db022f28bd26a16e2c5e8527064494dba0.jpeg) ![IMG_7529](https://global.discourse-cdn.com/growingmarijuana/original/4X/0/e/5/0e50fcbcb7dc80329fd03312a70ff078f59bf77f.jpeg) ---

Lmao that’s what I’m saying it was at only 60% with a 100 watt spider farm sf1000. They got my money…bastards. I’ve had a couple of people tell me how inaccurate they were. Thankfully @low gave me the proper readings at light intensity and height, well at least a good starting point. Maybe this will help op > [@Please help me with lighting issue](https://ilgmforum.com/t/please-help-me-with-lighting-issue/113131/24): > > Alright, now this is rudimentary but should provide some idea.

I dowloaded the “ppfd meter” app (home studios) and found my phone sensor was about 50% off the published PAR map readings. That sucked. But the app recommended a uni-t ut383bt (blue tooth) lux meter as it can connect to it via bluetooth and use its sensor. Much closer to the published par map readings now, only about 3% adjustment. Best $31 I’ve spent. ---

I figured for the fun of it I would do another test with one of the daylight lamps for seasonal depression that I have. I know for fact that it is set at 10k lux. So I used the phone and diffuser and it read dead on at 12” where it was supposed to. Just found it interesting.
