I personally think above 96% of revenue is by selling lighting, whether it’s ceiling light or desk lamp or other lights. so Light Master is mainly for complement of a closed loop, when you tell your potential lights customer that your lights are high quality, you bring out your LM from pocket and prove it in front of your customers. If deal is done and the sum is decent, LM can be given to customer as a gift.
so the priority should be placed on our own lights, in a word, for selling more lights product. as for other lights, will continuously improve its precision.
that’s my own understanding of the role LM is playing

And then a customer who doesn’t know what problems the LM3/4 has measures some other light source to compare and starts to realize he’s been duped… For such tasks the instrument should measure all light sources correctly.
In my opinion, this is a perfect example of not understanding how the device will be used. IMHO.

So the LM is just a (imho questionable) marketing tool to suggest the superiority of one’s own products against competitors? If that is the case, then it is clear why the whole thing has not been consistently developed in terms of usable measurement accuracy…

This can be a distant effect for several years. I found the first problem after six months. I started to look into it and it turned out that the problem was not in the LM, but in the microcontroller of the luminaire driver. And the big problem with distortion of readings in IR illumination was discovered by accident after 1.5 years. Many people still do not know about it. Your company may lose the trust of the customer…
buddy, sometimes I can not get what you mean.
" I started to look into it and it turned out that the problem was not in the LM, but in the microcontroller of the luminaire driver." this sentence means that LM is OK, the problem lies in the luminaire driver, and then?
Not only loses the customer trust in the company, but also trust in the device itself.
I am not happy that reviewer (which have a lot of influence in sales and image of companies) take masurements with only these Opple LM devices because they could be horribly wrong.
From my side, I cannot trust the LM (no matter if III or 4) longer. Because to wildly fluctuating measurements a serious evaluation is simply not possible.

Probably not a good example )))) It took me a long time to deal with this problem and then I didn’t use LM at all for some time because of it.
An example of how nuances may not show up right away.
recently, I am in contact with a person from hamamatsu photonics, I am consult with him the coefficient I mentioned above, I will verify his thinking. If it works, then LM4 ought to be as good as LM3, have patience please.
once again, I personally feel sorry for inconvenience caused, after all, users/consumers are innocent.

I think your company should reconsider LM3/4’s market positioning before it’s too late.

Is this for OPPLE v3 or the v4 ?
Your continued attempts to make this a better and more precise product in the face of such pushback from your management is a wonder to behold.
Thank you.
4 Thanks
Yeah, I agree. Very glad we got Steve, and not some random programmer who only does as the management tells and nothing more. Hope his superiors will eventually fully support him in his plans, and allow him to make the device as good as it can be 
5 Thanks
I hope you have fun here, iacchus!

kinda feel I won the welcome wagon lottery w/ that one. Alicia is a star.

Yep, I still remember Alicia from Aerosmith’s music video “Crazy”.

for flicker detection, LM3 and LM4 basically the same
I think that LM3/4 are not principal for OPPLE (now). But it is because of this that there could be problems. When buyers will get wrong readings when comparing products from other manufacturers (with other light sources) with OPPLE products.
How to explain to the average customer (designer, installer, etc.) that this device can only measure the light from our (OPPLE) fixtures??? Other lighting fixtures emit other photons that cannot be measured with our device???
I don’t understand this idea…
Light is universal, not only from Opple. Very weird marketing strategy to say the least.

I think the most prevalent desire here is to measure the light out of the front of the flashlight “SYSTEM” So, yes, if focus on an LEDs properties is the goal, you measure it independently. But I can see why @stevechang is confused… how did bit of minutia this creep into the conversation? What bearing does it have on the accuracy or usability for the tasks that we, as flashlight hobbyists, need to accomplish?
