Lux Light Meter Pro

Am I supposed to multiply the FC # by 100? 1000? I doubt my 400 watt HPS grow light is putting out 290 FC at one foot away. 29,000 makes sense, but I shouldn’t have to assume….

This used to be an exceptional app. Had a light meter that told you the lumens for whatever area you aimed your camera at. Now they’ve changed it and it’s just a big mess that doesn’t do what I paid for. Just a bunch of junk I don’t need and no instructions on how to get the old light meter back. What a joke.

Confusing app. I tried it a few times and now deleting it

I’ve measured this on the same light source, in the same spot, with my phone held at the same angle..& I consistently get different values over & over again!

Under controlled conditions readings changed by 1000 over several readings taken in sequence

I own the pro version and compared it with a professional stand alone (not app) light meter - the results were very different. It would be great if it could be calibrated.

This fails on all levels. Does not work. Don’t waste your money or time…:

Use the back camera it works better.

I downloaded LUX and paid for it. It doesn’t work.

Apartment house has overly bright and quite different hall lights and I wished to measure them. It worked well for this. The cavaet that it should not be relied on means I can't report this to authorities with authority, but it's a start--we'll wait until those authorities question our calibrtation to report that.
