My unit arrived today, it's really a remarkable product. Thanks for testing it against Minolta's units. I've seen other test against Sekonic and it was accurate as you showed. As a cinematographer, it is very useful for run and gun filmmaking, matching Ambient light and so, just wish they could make green-magenta shift easier. Again, thank you for this great video and testing it against fancier options. I would suggest you to change your title so you can reach a broader audience, something like "Can a Spectrometer be Cheap and Accurate?" or "Cheap vs Expensive Spectrometer - I wasn't expecting this..." Something like that plus product name. In fact, that's how I found out about the Opple, searching for "How can I measure Kelvin without selling my kidney" haha.
Thank you for this very professional review. Just remember that the CRI measurement reading by the Opple is CRI Ra ( 8 colors NOT R9) and the Minolta CL-500 read CRI Re (15 Colors), I´m pretty sure this is the reason when you see different reading numbers on both instruments. BTW Sice yesterday it is available version 4 ,,, I ordered one for test the new measurement options.
Amazing product, I was so surprised when I saw the price tag, beats the highly praised Radex Lupin while providing more info. Guess you could Radex is better with flicker testing, but since they are made in Russia, probably would be tricky to get one these days anyway. Too bad it doesn't show r9 and DUV, well you could use a calculator to figure out the last one.
I haven’t scheduled the flicker video yet but do intend to do one. There are not many simple to use devices which measure flicker which I would trust. Flicker can be highly subjective and has many parameters. This is a great document to get you started. www.energy.gov/sites/prod/files/2015/05/f22/miller%2Blehman_flicker_lightfair2015.pdf
Thanks. I'm searching for good light for the entier house. Just ordered Opple lightmeter and 2 led panels to test it. Hopefully they are somewhat good, as they have dimmer and rgb. By tests with mobilephone in light shop camera app did not get distorted when quickly point at light.
@@t7ank eeeek, panels? Rgb? Traditionally RGB is dimmed with pulse width modulation. It’s bound to look cool, but I would bet the white light you will end up getting from them will be poor, and the flicker frequency will probably be quite low. What kind of light are you looking for for the house? A down light? Where are you based?
Yes, i know this maybe won't be good. That's why ordered only two in different sizes, just to test. I ordered Briloner 7349-416 and -216. Hopefully they will be ok, otherwise they will go in less used rooms 😂
This is an amazing devices and I have already ordered it. Hope I can receive it soon.

Nice review. I just got the Opple V4.
Holy wow! The world needs this product!
Thank you for the review and introduction. I just bought this after watch! My goodness, so inexpensive now! ❤

I too am about to order the 4th model Opple IV. How did it compare in your testing ? I need something for lux and kelvin color temperature readings
Thank you for this helpful review! 👍
Thanks for the great review!
Thank you for the accuracy comparison, Matthew! It's a good device for less than $30.
Thanks a LOT for this Test! Very Usefull ! Like & Subcribe from Odesa, Ukraine!
Thanks for the insights. Very helpful indeed.
Wow! Amazing, man! Thank you!
I love to see the comparison for non continuus light sources, for example HPS streetlights.
Thanks a lot for this video. Is there such a tool to have R9 measurement too ?

Radex Lupin was an interesting device when it had a price of $73 (summer 2021). Then the price went up and now it costs more than twice as much!
Can this device help to discover the pwm in a LED / OLED TV / PHONE? Change brightness until the least pwm possible? Thanks
THNAK YOU
Can this device be used to measure the color temperature in Kelvin of light sources for photography ?
When does flicker video comes out? Can you compare Opple to any other measuring device to measure flicker?
I haven’t scheduled the flicker video yet but do intend to do one. There are not many simple to use devices which measure flicker which I would trust.

any updates with newer version 4?
The product doesn't seem to be available anymore. Anybody with a hint to the manufacturer?
i am from the manufacturer of opple ,if you need it you can contact with me.
I don't know what is this can someone say what we do with this thing?
