It's not using the same App as the Light Master 3 (which was called Light Master Pro)
Once downloaded, you kind of have to sign up for it to work. Mine didn’t work trying to use it as a guest
You can use this App for Opple Light Master 3 (pro) as well, so you could remove the Light Master Pro App if you want
Please make sure you read this thread before you buy one!
The Opple Master 4 is not yet ready for accurate readings… as of June 2024… but stevechang (Steve) is working on a desktop app as well.
August availability, huh? I wonder if the people that recently ordered will be waiting until then for shipment.
The AE page had no indication of that. In fact they say 160 in stock???
Note: DO NOT BUY - Wait and see if problems are resolved.
The Opple Lightmaster 4 could give erroneous values in all the important parameters such as CRI, R9, Duv, CCT. Company is trying to correct problems but as of 5/2023 there is no fix.
This is what my email from Opple states:
“We are very excited to report that the Light Master IV(4) has now been released.”
And order from Aliexpress - maybe standard with every order, but:
“This order will ship in 9 days. If not, your refund will be issued automatically.”
Fingers crossed. Sending exciting email for product not available until August would be unnecessary poor form so I hope this baby will be in my hands soon.
You have to select the correct model. The price defaults to the V2 device… Go down to where it syas “color” and select the V4. Th picture will change. AND, the price to $39.65 (US)
Yes, but none of those apply to the meter… so they are stuck using “color”… or so I guess.
I have seen other vendors use “color” for things like size of clothes or length of wire…
So an educated guess is that they used the only option they have to allow a selection of models.
I just put in my order for the 4th Gen meter.
People look at me weird for having dozens of flashlights… This will give them something else to talk about, LOL.
The FCC filing for the Light Master IV from February contains detailed internal photos. From these you can see the spectral sensor has been changed to either an AS7343 or AS7341, both of which are a significant upgrade over the original. They still only have a very limited number of measuring points compared to a dedicated spectrophotometer, but it’s definitely a more capable device than the previous version.
Very strange. When I saw that thread about Opple 4 yesterday I ordered one. Today I saw in my AE account that is is already shipped. Myabe Opple 4 will need some certification to be released in EU. For chinese market that it is not problem.
