Anybody with a lux meter wanna help me out?

I got a lux meter app. I'm wondering how accurate it could be. does anyone want to compare it with a real meter?

It hit 112000 under one of my hps . this makes sense because all my shit is getting burned up.

I got a lux meter from amazon cheap delivered, only thing was it read zero....because i did not know that lux meters dont work with led's
