## LightSpectrum Pro Description
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 Reviews in United States

### ***** "Great Spectrum Tool"
Just got this app and held it under our Halogen and LED lights and our LED grow-light. This app is sensitive: the grow light has rows of different color LED and as I moved my iPhone the data changed with small moves. I think it will work great. And I love that there are no (that I’ve discovered) additional in-app purchases like so many apps have nowadays.
-- SanFranFotoShootr, 2025-01-18

### ***-- "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.
-- M22222299999, 2024-04-08

### **--- "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!
-- firelightdp, 2022-05-29

### ***** "Great app"
This inexpensive app does a great job on my iPhone of measuring light color temperature which is exactly what I wanted!
-- RonKirkland, 2022-04-14

### ***** "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.
-- QuarkUnit, 2022-02-13

### ***** "Worked well!"
I have a flashlight collection with emitters that are color temp calibrated to temperatures such as 2000K, 2700K, 3500K, 4000K, 4500K, 5000K, 5400K, 6000K (and more!). 

I found that this app got CCT correct within 100-200K when used properly. I took a white sheet of paper, shined the light on the paper, then read the paper’s reflection. Aiming the app at the flashlight directly gave skewed results by 1000-2000K upwards.

It’s so accurate that I had a light I had mislabeled as 6000K, and it kept coming up as 4950K. I checked the LED bin (XP-L HI V3 3A) and it was actually 5000K! So the 4950K was dead accurate.

I did notice that as you move away from the 4000-6000K range, the ratings are less accurate. For example, my 2700K lights red as almost 3000K, and 2000K lights read as 2700K. My 660nm pure red lamp reads as 2400K. So keep that in mind. But this is a great value for $2!
-- Cheule, 2021-05-31

### *---- "Overcharged"
I was overcharged the amount of $18.38 when I purchased this app. I need a refund and you need to fix this issue.
-- BigCeaseHataProof, 2021-04-06

### ****- "Misspellings"
Some old-fashioned people think that a quality program should have no misspellings. So think about ‘cancel’ and ‘wavelength’, please. Aren’t you embarrassed by these errors?
-- Enilohclyteca, 2021-01-18

### *---- "Scam"
App does not measure spectrum.  iPhone does not have spectral sensor.  I compared this apps readings to Sekonic C7000 spectrometer and a Photo Research PR670 ($20,000 instrument). This app’s readings are completely wrong.
-- W Chang, 2020-12-30

### ***** "Super cool!"
First, the fact that it does what normally takes thousands of dollars in tools is fantastic.  No, it's probably not nearly as accurate as pro devices to do this work and having said that, since I don't have access to pro-grade tools I cannot say how the accuracy of this compares.  But now I have a way to quantify the various values of light sources, and most helpfully, I can compare them objectively.

This is certainly an app that every art, theatre lighting and photography student should own.  Such a good learning tool to see how light sources and color interact.

For homeowners this tool helps sort through the spec's of the multitude of light bulbs at the big box stores.

I'm using this on an iPhone 6s with no problems.

My only complaints:
-The interface can get cluttered.  Using it in landscape mode helps that quite a bit.  In portrait mode, at least on my little phone, things get piled on each other.  Wish it would run on my older iPad!
-The helpful explanatory tips are good, but I wish I could figure out how to shut them off.
-I wish I could take screen shots in landscape view.

Wish:
-Now if it had a way to measure flicker of bulbs!  Don't care, make it a separate app or make it a purchasable upgrade for this one.  I'd buy it!
-- nickname92829, 2020-12-26

### *---- "Very misleading"
This app claims to show you a spectrum of the light it is observing.  This is impossible since each IPhone pixel can only measure the relative strengths of the red, blue and green light entering the camera.   This makes suspicious of every bit of data the app displays
-- gw734, 2020-12-16

### ***** "Color temp without external hardware!"
I was looking for an app to measure color temp without external hardware. I found this after trying several others and was very pleased.
-- knightontherim, 2020-12-13

### *---- "Amazing?"
Amazing?
-- tfgtftt, 2020-09-24

### ***** "Wow"
This is an amazing application. You did a phenomenal job, thank you!
-- Patrickjpaschal, 2020-08-30

### *---- "Camera issues on iPhone X!!"
There’s a serious camera issue when opening up the app on the iPhone X on iOS 11.4.1. Video/picture feed is super fuzzy and not sharp at all!

Update: AUG 2020, 2 years later and the camera issue has NOT been fixed!! I’m now on an iPhone 11 Pro Max running iOS 13.6. This app is still having issues focusing both the rear and front facing cameras! Anything in front of it still remains unfocused!! There is still no tap to focus option! What a disappointment and waste of money!!
-- 𝖈𝖆𝖓𝖛𝖆𝖘, 2020-08-05

### ***** "Impressive app"
The app provides a detailed spectral graph using data it collects from the iPhone camera.  Very impressive and useful for light analysis in various environmental conditions. Kudos to the developers!
-- sunj, 2020-06-13

### **--- "Works on older devices but not iPhone 11 Pro"
The description really should say which devices this app works on.  It doesn’t work on an iPhone 11 (the numbers don’t change at all), but it does work on an older iPhone 6s that I happen to still have.
-- Fireguy360, 2019-11-13

### *---- "Only ever reads 3900"
Can’t seem to get this app to work and it only ever offers 1 color temp reading.
-- Tk321Why, 2019-11-09

### ***** "Helpful app"
I shoot indoor sports in a variety of poor lighting. High school gyms.  This app was recommended by another pro photographer and it has proven to be very helpful.  While I shoot in raw, it’s nice to get the white balance correct in camera as a starting point for editing.  This app does that.  
I especially appreciate the spectrum display which helps me understand what’s behind the K value.  
For sure worth its small cost!
-- BillWayToday, 2019-11-08

### *---- "Doesn’t work on iPhone 11!"
Just purchased. Doesn’t work at all. 
Numbers/measurements aren’t changing in response to changing position.
Camera not focusing.
Please fix!
