Meter was buggy developer helped me out
calvinacosta

My power meter was not functioning properly after an update but I reached out to the developer and they helped me out. I use this meter for all of my shoots so it was a real handicap for me not to have one. It works just as well as any traditional light meter and fits in my pocket! I HIGHLY recommend every photographer videographer or lighting technician invest in one of these


Connection issues
doesnt sync with app

Purchased item on BHphoto couldn’t get it to work on my older iPhone and new iPhone 11 max. Customer service has been a pain. I reported the issue back in January and still no follow up. The issue is the connection port doesn’t fully hold inside the lighting port falls off easily and doesn’t pair to the phone to sync and use app. I don’t know why I can’t get app and device to work together. Spent a lot of money on this and it have been a waste.


Works wonders
Kyle Camerer

I was skeptical at first about the accuracy of the lumu before I ordered it - it's spot on everytime. It's been one of the best tools in my kit.

After buying Lumu and given the impression that it would do color temperatures and then installing the app I find out that now I have to put out and extra $160 more. Gives a bad taste when you are not up front on giving the whole story


Great for film camera

This has a lot of built in functionality to take care of your light metering needs. You can add ND filters and do spot metering. This is the best light metering app I’ve tried.


Described very good to be true
RM_CR_2016

I downloaded this app for color temp measurement but this is the tricky to attrack customers to buy a separate device required that cost ~$400 and more. I don’t recommend it, if you need to know the color light temperature, search for specialized testers instead of this “free apps” that make us to waste time.


One star
Nulalee

Until you guys fix my $250 light meter that heavily depends on the iPhone only and a app. I recently updated the app on my phone after been prompt to do so. After the update my light meter doesn’t work. The phone don’t even recognize it any more. I’ve email them for help and have yet to hear back! Still waiting!! .... UPDATE! It’s been 2 weeks and still have yet to hear back from these guys. paying this much for an a light meter that stops working after 3months is not fair at all. Do yourself a favor and look else where for a better light meter.


Does the Luma “Pro” Dome require In-App purchases?
Jamdalu

The app is really nice! I am ready to purchase a dome and would like to know if the Luma Pro dome requires additional in-app purchases to “unlock” the pro features. Are the in app purchases merely upgrade options for the lower priced units? The pro model seems to have everything unlocked at $499 when combined with the free app, since it’s the only one without this flag: * If necessary, additional modes can be unlocked directly from the app after purchasing this model. Do all three domes share the same hardware, upgraded by the app? I want all of the pro features, and would like to know the final cost to unlock all features. Thanks!


Not as good as I thought
Heath Shelton

Just received my lumu power and it does not read flash as good as my 21 yr old sekonic. I have to be right next to the flash before it will read. I can not stand where I put my subject and read the flash like I do with my sekonic. I was excited to get because I would not have to carry an extra device around but I’m gonna still have to.


Try this app first!
a random player named jon

Just what I was looking for! I have been looking for a luminance / light measuring app for an experiment I am doing for a long time. I have been through a number of apps before this one, which finally met the need! Other apps hit you with frequent ads, or don’t let you make camera adjustments, or don’t show results in real time. This app is either ad free, or low frequency of ads, lets you make camera adjustments, and shows results in real time! It allows for a number of adjustments, is easy enough, and seems to be fairly precise in detecting fluctuations (which I am looking for). A big thank you to the creator(s) of this app!
