## Lumu Light Meter Description
The light metering tool for every great image maker. 

Use the standalone app as a reflective light meter or use it in combination with  Lumu Power hardware for professional Flash and Color Temperature measurements.

A new expression of what a light meter can be, Lumu meets the needs of enthusiasts, professionals, and students who find existing light metering solutions too bulky, expensive, and complicated.

“The Lumu Power is without any doubt the most full featured light meter I have ever owned. It’s tiny, it weighs hardly anything, it manages to offer a feature set that expands way beyond what most will ever need from such a device.” - www.35mmc.com

## Lumu Light Meter Reviews in United States

### ***** "Great but"
Great but one broke they would not replace it so I bought another.
Then that one broke. Very expensive for plastic housing
-- MLPRFAP , 2025-05-17

### ***** "Best Cine light meter"
This is great app, and LuMu hardware is working great (exceptionally precise). I’ve compared it to Sekonic 858d and it’s giving more precise readings in light levels.
Color meter is in par with more expensive professional meters.
Great to see they are back on app store!!
-- Mixamana, 2025-03-19

### ***** "Wow"
Listen, I never write app reviews. I’ve never even thought to write an app review. But this is probably one of the greatest, feature rich apps I’ve ever used in any use case. Not only that, but it’s also so visually pleasing to look at, not to mention super well designed and laid out. Five enthusiastic stars!!
-- KeegsCook, 2025-03-10

### **--- "Terrible customer service"
Ordered the Lumu power 2 from them directly and never received it despite being charged. It's been over a month. They've ignored my email and the contact page in the app didn't work
-- Nick Petroski, 2024-06-18

### *---- "No setup instructions it is trash"
How do you set a fixed ISO? No instructions, nothing, nada, zip.  Deleting app as it is pointless and useless for film.
-- Dfkfhkjgcjis, 2024-04-20

### ***** "Honestly"
I first downloaded this at the beginning of my film journey, helped me walk through the door. Now, as a creature out of habit, I still use this app. I’ve learned the nuances of it, so after I meter for the highlights and or shadows I just kinda “have a feel” for it now and use it as a referencing point. And honestly, isn’t that what any light meter app is for with film? Just to give you a stable referencing point for you to play off of?
-- Devbot801, 2024-04-08

### ***** "My Primary Meter"
This is a fabulous and convenient product that I use on every photoshoot.  The color meter mode is essential for my architectural work, and replaces my Gossen color meter.  I rely on the incident meter mode as a starting point for my interior shots.
-- rablakely, 2024-02-19

### *---- "Discontinued product. Do not buy."
Their website is still up and transacting. Do not buy. They do not respond to support or any requests.

This was super convenient. Bummer they shut down operations. They could have at least turned off their website, social media, etc so everybody would know they’ve closed operations…
-- uberfoto, 2022-10-08

### *---- "No Longer Works"
I purchased a Lumu Power Light Meter in 2017 and it’s been working great till the past two months. I’m able to connect the device to my phone and it seems like it’s working, but the color temp readout option doesn’t appear any more. I tried re-installing the firmware on the device from the app, then restore purchases, and even tried to buy the color temp option again. No luck. Contacted support three times now, and have not gotten a reply. Used to be a great product and app, however it’s gone south. Look elsewhere if you want to have a product that lasts. Sad.
