Description
Smart Lux meter is a tool in extended set of the Smart Tools® collection.
This Light Meter measures the ambient brightness with embedded light sensor. It is used to adjust the lighting required for plants or to check the brightness of a study room.
Usage is very simple. Make sure that your screen with the sensor is facing the ambient light source (lamp, LED lighting, window, sun ...). If the sensor is facing your face or ceiling, the measurement will be poor.
The measured value can be used for reference, and optimized by [Calibration] menu.
In the morning or evening, sit by the window and measure the world getting bright or dark. It will be an interesting experience.
* Do you want ad-free version? download [Smart Meter Pro].

Helped me out!! Testing blooming FAKE AND Counterfeit torches. It's BRILLIANT!! You pay for the torch, it arrives, and you open a case with the company you order red from. You tell them the advertised item says it does 900,000lm and I say its 300lm! The SELLER has to prove it is as advertised (By proof by the maker!!) And usually they can't!! So you get a full refund. BUT, IF YOU ARE ASKED TO POST IT BACK?? 😂 Tell them you can't as it IS illegal. You cannot return by post ANY Fake items.

Doesn't work at all. Never asked permission to use the camera, but continually displays results around 180 - 220 Lux which is typical indoor light. Covering the camera, or putting it right in front of a calibrated 10,000 lux source it still displays figures in that range. This app appears to be nothing more than a random number generator.

Not giving accurate readings.... Gives different readings in same conditions

As an electrician ill say this... It's handy. Seems to have difficulty in rooms with warm and cool lighting combos and with high bays. But for the average run-of-the-mill dink at home...it should be alright...like for all you dope growers. It will change your life. But there's better stuff out there for the more advanced minds.
