Not even close to accurate: buy a real Luxmeter. – MEGAMAN® LuxMeter Review

I purchased this (and a few other iPhone luxmeters) to help with planning lighting changes in a bathroom and kitchen. The readings are so far off from each other (from 50 to 1270 Lux at the same time, on the same spot.) as to be very suspicious. I finally bought an $80 real Lux meter. I don’t use it often, but it is always right on the mark, with repeatable results. This really doesn’t work.
