Light Tester

Light Tester


A simple light sensor app that displays the illuminance of any light source or ambient light. Displays values in lux and lumens per sq ft. Great for horticultural grow light testing if your phones sensor precision is high enough.

hasn't been working on SGS devices, latest upgrade may have helped the SGS problem though if you want to try it out and let me know.

It really depends on the phone hardware It really depends on the phone hardware to display somewhat accurate results against an actual photography light meter. I tested it on a Samsung SIIx and results were okay (accuracy -18%), but then I tried it on a Samsung S4 and results were better (accuracy -/+ 7%). I also tried it on the Sony Xperia and the results were similar to the S4 (accuracy -/+ 9%). So bottom line, not bad and was what I expected for the hardware used. Just easier than lugging my light meter with me when I can easily whip out my phone.

Great & Simple to Use I needed a simple light meter to estimate the lumens/sq. ft on my reading desk and this really did the job.

Not at all accurate. Tested with digital light meter. This program far over estimates light readings...
