Lux Light Meter Pro Reviews

Maybe I’m using it wrong, or maybe I don’t understand lighting, but I really don’t think this is very accurate. I was measuring the intensity of my grow lamps since I’ve got new bulbs and a new set up, and wanted to make sure I could get as close to this old set up as possible and maybe even get some extra lumens in there. The bulbs I was comparing are 840 lum vs 1200 lum, but the readings were all over the place.
When looking at the 840 bulbs, I got an average reading of 340, even when it was two and three lamps “stacked” on top of each other (which I’ve heard from other plant people increases the intensity of the lumens on the plants).
I was also getting readings of over 12,000 lum on a bulb and hood combo that I know is more dim than that, seeing as my plants are typically stretching under this light (low end recc of lumens for succulents is about 2,000). The readings just feel wildly unpredictable.
This is more a gripe with my phone, but also be sure to know that front and back cameras take in light differently. A spot which would read 330 lum on my front camera read as 380 with the back.

Even if the numbers are wrong, the “average” and “ratio” I found at least helped me set my lamps up in a better pattern.

First, I just wanted to test a light. So I tested the beam on my wall. And it gave me a reading. 20. So then I tested a dark spot like my pocket. He gave me a reading zero. So I tested the same spot again and it gave me 20 again. I was amazed I thought this was good. I could repeat this over and over again. I thought wow what a wonderful app. Next, I decided to switch to the rear facing camera is it in the front, this is where the problems begin. Because I cannot actuate the camera while hold the phone flat against the wall. That was frustrating. So I switch back to the front camera. The reading that I just got for 20 is now too. That’s a huge difference. So I repeated that test over and over again and got the same result wild fluctuations.

Got this a few days ago and it seemed to work fairly decent. Using it to compare lighting in different areas.
Went ahead and paid for the pro version.
Next day it will not work. Does absolutely nothing. Checked it off and on for the past couple of days and it still does nothing or at best gives some ludicrous reading then freezes up. Went to the feedback area in LuxLightMeterPro where it says u can contact them several times. Getting a message ‘trying to connect thank you for your patience’. Never connects.
I guess I’m not THAT patient. Deleting this trashy worthless app from my iPhone X.
I’ll never pay for the upgrade again until I use it several days with success.

You can take a quick measurement with one tap, or press and hold the sun icon for continuous capture with averages.

The back camera seems to be most accurate. If you wave it around in the area needed, you can measure the average amount of light.

Open your camera and point it at something. assign a numeric value to the light level pointed directly at the sensor. you just created a lux meter that you can sell in LuxLightMeterPro Store..... this is a completely inaccurate way to measure light levels in a room. The main problem is that the sensor only detects light pointing directly at its field of view. Lux is a measure of light over a surface of one square meter. A real Light Meter measures light indirectly, that’s why they have that white globe around the sensor. The bottom line is that I tested LuxLightMeterPro beside a real light meter, and the results were wildly inaccurate. If you’re just looking for a toy to play with, then go ahead and pay the developer $3.

Should be really straightforward but it’s actually not which makes it inaccurate. Sometimes it works from the front camera and sometimes from the rear camera. I’m trying the free version so it’s I can’t switch the selection (always says front), but I have done a bunch of experiments covering one or the other and it’s always different. I’m not a photographer (using for simple measurements for mediating circadian rhythm) so I don’t need fancy features just want to measure and have it be somewhat accurate.

Yes, technically LuxLightMeterPro is “free”. LuxLightMeterPro opens to tell you in order to continue you must either purchase a monthly subscription or pay for LuxLightMeterPro upfront. I don’t have a problem paying for apps, but if you’re going to charge for it then just put the price on it and don’t pull the sketchy stuff were you say it’s “free” and then LuxLightMeterPro literally does nothing except take your money before you can do anything.

Don’t download this. I paid the $2.99 to unlock pro thinking LuxLightMeterPro might function better and I was wrong. Don’t waste your time with LuxLightMeterPro it can’t read light at night at all. There used to be another app that I forgot the name of that did everything LuxLightMeterPro should be able to do and actually worked and it was free. LuxLightMeterPro functionality is trash and I wish I could get my money back and delete this garbage app.

Downloaded this to see if it was worth getting the pro version. The ads at the bottom prevent clicking on the bottom menu. The UI doesn’t seem to make sense to me. I don’t see speed, aperture, or ISO anywhere. Just FC and LUX. In fact I wonder if this is even a light meter for photography. If not, then my apologies for the poor rating.

If you’re looking for a working light meter...I don’t think this is for you.

It’s not bright out, a working light meter shows 1/60 second, f2, iso 800. Now, maybe that’s low, might be less than one lux, no idea. But if it is, add a decimal. 0.1, 0.01. Getting nothing but zero is useless and makes you questions if it’s working at all.

I did try pointing at the sky. It quickly flipped back and forth between 1700 and 6. Anything ground level still zero.

It’s plenty bright to take photos outside. I’ve taken several to verify.

Using it for a few days now, works as advertised and has been useful for knowing if I am getting enough light early in the day. Could be useful for determining locations for plants as well.

I do lighting design for work, so it is nice to have a light meter app on my phone for on the spot measurements, but it doesn’t seem to be very accurate. I did a few comparisons with a DLM112SD meter we have at work and they were very different.

I received a notification that LuxLightMeterPro had copied the contents of my clipboard. This means it had accessed it without me telling it to paste anywhere, and it did so without asking permission. This is a classic hacker move: your clipboard can contain sensitive information, which is then easily sent to the hacker. Who knows what else it’s reading?

I will be deleting LuxLightMeterPro and avoiding anything by this developer ever again.

Got the free app so I could measure the light and sun into our apartment block as the property speculators want to block it with a new hotel. Will get the paid app for my partner who likes photography if it works well. Seems to be good and not many permissions - like that a lot!!

I wanted to find the best place to put a new plant. I tried it on a place where some of my succulents are growing fine and it said my fc was 26. That’s really really low (like too low for anything to survive). It said that everywhere was around 14-77 fc. I think it really lowballs the light amount. I wasted way too much time with this and I still don’t know where I should put my plant

I got this for science class and the whole time it kept telling me to buy the pro version so if you fix that LuxLightMeterPro will be 5 star

I did not realize how much of a difference there is between led and fluorescent lighting in my shop. I was able to measure each work station to direct or add lighting to make the lighting consistent .

Does what it says it does (strangely so rare) with a clean interface. Simple, elegant. No needless registration. The price to remove ads is quite reasonable and supports the work this developer invests in LuxLightMeterPro. Bravo.

Seems to give widely varying readings in same light settings.

The thing that worries me most is that it captures clipboard contents on load. Why is it doing that? If you use a password manager and have pw copied for something else then open LuxLightMeterPro it loads your pw.

What did you expect? Some glitchy pro things, able to acces pro features for free. Fun to play with, don’t know about practical use.

Take some getting used to more options than my previous light meter

Downloaded this and removed it within 15 minutes. Interface is great, but the pop up ad people are talking about is the prompt to upgrade to pro. One button and you’ve given then money. Close button is barely visible on this screen and all it takes is one time not paying attention. Feels icky and trying to trick users. No thanks.

Super useful. May not be exactly accurate but it is very helpful for determining if something is getting as much light as you think it is compared to the rest of your space.

For some reason as soon as I downloaded LuxLightMeterPro in my phone I got a prompt asking me to sign into my google account. While I was deleting LuxLightMeterPro I got another prompt asking me to sign in to google again. I don’t know what that was all about. But anyways LuxLightMeterPro is a joke. When you press the “sun” button or hold the button it doesn’t give any readings. Waste of time.

Been shooting film for years. Using a light meter is a necessity. LuxLightMeterPro keeps one less item from taking up space in my camera bag. Highly recommended

I have the free app. The ads cover the bottom row of icons, and are unmovable. Disappointing. How can I move to the pay app if I can’t see what I have?

Fairly accurate if you look at the bottom average number. You have to hold it steady for a few seconds, then look at the average # below. I have compared it to some Lumens Brightness Charts! Not bad for FREE!

I was able to determine where I was getting the ideal LUX, with an easy to read, real time readout, in bold numbers you can read very easily. Perfect, must have app

Its on point with every type of light except LED
