Hi there. Please take a look at this photo of my Opple.
Got mine nearly completely drained (1%!) and it terminated charging after an hour or so but the app indicates 95% capacity on the unit. Not good, the internal cell looks to have taken a capacity hit. Micro USB was slightly misaligned but had no problem plugging a cable in, still slightly misaligned after initial charging but doesn't hamper functionality. So far I've tested my room lights and it seems to read within the expected ranges, I'm waiting for complete darkness before running some real tests.
It's tiny, and looks like a great device to mess around with, especially for us enthusiasts. The battery's condition worries me though, and it looks like the LMP G3 I got sat too long on a shelf discharging to low, unhealthy levels.
I do not have this device yet, but wonder if anyone knows:
If the internal battery fails in the future, will the Opple Light Master be able to still be used with full functionality while being powered (charged) through the device's USB port or is the device essentially useless at this point until the internal battery is replaced (assuming a suitable battery is available for purchase and you are capable of replacing it without damaging the device)?
FWIW I'm charging the device right now after running some tests and it runs/connects to the app while plugged in. That's not saying it will work this way if the battery's trashed, but it just might.
Also noticed that I only consumed about 20% of the LMP G3's battery after two hours of on and off use. Respectable for such a tiny internal cell.

Default test distance is 2 feet except for lights that overload the LMP, hotspot centered on sensor. So far I'm satisfied with the data that I'm getting from this budget meter.
Edit: format + moonlight
Yay!
I respect that you did a lot of work to add the calculated DUV values… that is VERY useful imo
enjoy!
I’m hoping a newer version has Duv, R9 and the possibility of storing the data. If Opple does some feedback research and sees this thread.
I finally received my replacement and as promised, they sent me the pro version to replace my DOA Version 2. The Pro version seems made much better, the outside is aluminum vs the plastic on the version 2. Now time to start testing all my flashlights and house bulbs.
So, 2 thumbs up for the Opple Store on Aliexpress for standing behind their product.
For the price I that paid, I feel it's one of the best values of anything I ever bought, flashlight related or otherwise. There was a BLF gold star award, this would be it.
Opple Someone once hosted a picture of a “III Pro” (iirc) model app that showed R9. I guess it was not reliable enough. Too bad this picture has vanished.

Edit2:
As the chipset is EOL, and someone chimed of a better replacement, if the venture of an affordable light meter is profitable, then perhaps it may be of interest for them to include some added features.
I for one use the device occasionally for the Ra and Flicker index. Recently it failed to connect with my phone. Only then I realized my loss of a nice instrument. A week later it re-connected as prior – no change of any of my settings. It made my day. It’s to say that I’ve come to rely on the device, regardless of lacking some features.
I’m going to try a dispute with Ali and then most likely with PayPal as I expect Opple to take the low road as they have in messaging with them. The II I received has the aluminum housing, by the way. From what I gather they’re just trying to move stock without much care of what is shipped vs. what is ordered or displayed on the page. They basically told me to take a hike…“ship it back to China, when it is received we will issue refund.” I mentioned a few of the comments/experiences on this forum and they went tone deaf. It’s been a month of trying to be friendly and nice about it, I’m done, screw Opple. They are the first vendor on Ali that I have had a really negative experience with (out of probably a hundred orders or more from a couple dozen vendors…only had one claim out of all of those and it was taken care of immediately in my favor…for something that was only a couple bucks).
I’ll be up front, I don’t know that this Opple device is actually good for our hobby. In general it’s imprecise enough to make results other than flicker and color temp suspect and not really repeatable. There’s just no way it can substitute for legit testing equipment. And that’s fine, except now we have at least a half dozen people/reviewers that are spouting Opple data everywhere. I’m not sure it’s helpful for the scientific/physics measurements and it’s possible that the inaccuracies are unfair to manufacturers of both components and complete lights, especially when these people do not seem to have a complete understanding of things.
It was worth a shot, maybe I’ll get my money back and if not that’s ok. Seriously thinking about dropping the money for one of the Hopoocolor units but that’s a fair commitment in $$$…but it will do the job for flashlights and more. The Opple is really intended for large area room lighting, and it seems ok-ish for that (which is what I really bought it for, understanding its limitations).
Thanks! It helps in classifying the lights I already have so I don't get too redundant with my emitter choices :) It's more for me than for the forum (heh!), but I'm happy to share my data!
He makes some good points about each device (Opple vs pro). I'm not saying my results are precise, but for my uses (comparisons between my OWN lights) it's all I need. As with all non-standardized tests and devices, take these all with a grain of salt. The LMP G3 matches my expectations though, so I still think it's a great device for the 20ish bucks I paid for it. At least the one I got is!
Opple Light Master Pro
examples of how useful it is for me
I received a Novatac with an Osram Square LED. I did not know the CCT, DUV, nor CRI…
The Opple answered all those questions for me.
.
I also recently installed a 519a 4500k… Opple told me things I would not have known otherwise:
.
here is a 3000k 219b:
.
I also recently put a 519a 3000k in a light… again Opple helps me catalog the details:
.
and a dedomed 519a 3000k:
.
My Opple is a very useful tool, Im really glad I have it.
Beautiful. I wish Simon had warmer CCTs of the 519A, but I guess I'll try out dedoming 4500K 519As until he expands his CCT choices. Based off the -600CCT change on your 3000K, a 3900-4000K 519A sounds appealing to me!
I'm thinking of testing a WK30 on this thing - will the sensor survive being lit by a UV emitter? I think the WK30's red emitter's are ok, not too sure about the UV though - not even sure if it'll pick anything up.
People, Correllux’s beef is with Opple Customer Service. I would side with him on that point. Deceitful webpage product description and price jacking.
As for the results, there isn’t a consensus on the methodology. So his point on repeatability is valid. I don’t dare publish any of my results as I’m using a lightbox that evens out the beam’s characteristics. It gives an averaged illumination, albeit the reflected light has the box’s colour and I have to tone down the intensity (the Opple has a max of 50,000 Lux) and that skews the spectrum / flicker. So when our members post their values, it would be nice to also have the output setting and distance from the device. It’s assumed the emitters max output and the measurement is in the hotspot.
As bobvoeh was given a replacement (they have some LMP 3), and if Ali sides with Correllux, Opple could fork up a Light Pro 3 as his contention is about the lack of CRI and Flicker Index on Model 2, which was not stated at the time of purchase.
Im loving it, recommended…
my dedomed 519a 4500k dropped to about 3400K
.
has not left my pocket since I dedomed it
here is a chart showing the effects of dedoming various 519a (pic thanks to azhu)
.
note that LEDs CCT can vary +–200K
for example the 4500k 519a on that chart, actually started out at 4300K, so the dedome dropped 900K… CCT also varies +–200k based on how high the output is set to.
my 519a 4500k was the same as in the chart… it also started 200K below nominal 4500k… and ended up at 3400k… It is Very Nice! Just Do It… lol
I was planning on doing it on an S21D, but I'll try it out first with a single emitter light like an S2+ to get some practice :)
I'd like a 3400K light, I'm surprised at how huge the difference is dedomed.
I hope you are able to get a positive outcome. Keep us posted.
