With LightSpectrumPro EVO you can measure the color temperature of a light source without having to spend hundreds of dollars on professional devices. LightSpectrumPro EVO has an error of 2 - 8% compared to existing professional products on the market. in addition to the color temperature measurement in Kelvin, LightSpectrumPro EVO allows you to view the color spectrum of the light being examined with a band ranging from 360nm to 800nm. in addition to the spectrum it is possible to display the position of the white point on the CIE 1931 diagram and to apply a filter for wavelengths to display in overlay on the image captured by the cameras which elements reflect a specific frequency and with what intensity.

LightSpectrum Pro FAQ
Is LightSpectrum Pro free?
Yes, LightSpectrum Pro is completely free and it doesn't have any in-app purchases or subscriptions.
Is LightSpectrum Pro legit?
🤔 The LightSpectrum Pro app's quality is mixed. Some users are satisfied, while others report issues. Consider reading individual reviews for more context.
I have no experience with professional equipment in this area but this app I like a lot. I have it some time now and use it to look at color temp of light sources and especially the blue color component. Although my very 1st experience was not very good, app crashes/freezes, I must say that past years (2020/2021) the app has become a lot more reliable and stable. Last time I checked there was no other app that has the functionality offered by this app. The UID maybe can be better but after some practice its not that difficult to work with.
Fine for non-pro purpose
The interface is somewhat strange, but it’s workable. The lux and kelvin values seem accurate, but on my phone (iphone 12 pro max), you have to keep the phone pointing dead straight at the source.
So i’d say it’s fine for hobby purposes.
Absolutely use less
Very low quality and not accurate at all.
Even you can’t get a basic estimation about the light conditions.
More than that, its user interface is a disaster.
I payed the price for purchasing and tested it on iPhone 6s, Ios 13.3.1
It is working great on iOS 7!
This apps work great with iOS 7. Very easy to use and it can give you a lot of information. Just tap on the screen and it will give you the temperature in Kelvin. I don’t know how accurate it is, but first impression is good.
Not working
This App does not work at all.
Not working
Absolutely not working.
As a video profesional I Would love to have an app that could give me the color temp of a light source. Unfortunately this app doesn't work at all. Doesn't even activate camera.
iPhone 5 (MD622DN)
iOS 6.0 (10A405)
Pretty good overall
I have some LEDs where I know the wavelengths, and under some combination lighting conditions the app is super inaccurate—but under lots of conditions (including combination ones) it’s very accurate. Useful tool, overall. I wish they would fix the inaccuracies but I’m still glad I have this app; there’s no other app that has a full spectrogram right now.
Needs a target on the screen to only measure that point
This app needs to have crosshairs or circle at a point on the screen, to only take measurements. General averages of the picture isn’t a great feature. Spot metering will make this app awesome!
Great app
This inexpensive app does a great job on my iPhone of measuring light color temperature which is exactly what I wanted!
Quite accurate!
I used to use a $2,000 light meter to measure color temperature when I worked in the film industry. This meter costs only a few bucks and is almost as good. The app description says it’s within 8% of the actual color temperature, which in most circumstances is sufficient. I tested the app in a variety of environments; I.e. outdoor sunny, outdoor cloudy, interior lights, balanced to daylight, cool white, etc. and it worked great. If you’re doing scientific measurements it might not be what you need but for film and video it’s pretty great.
