Branded flashlights way out from specifications

I just want to discuss about branded flashlights that are way out from manufacturer specifications.
For example Acebeam L18 and Nitecore P30 new. I know that there is too many of them but this kind of ‘‘ultra branded’‘ flashlights and more expensive with the price they should not allow themselves this things.

Acebeam L18 is rated on turbo 1500 lm and I measured only 1050 lm, high is 750 lm and I measured 657 lm.
Nitecore P30 new is rated on turbo 1000 lm and I measured only 807 lm, high is 400 lm and I measured 390 lm.

Convoy M21A with KW CSLPM1.TG is 1087 lm that I measured for example.

Comparing Convoy and Acebeam that have same LED, performance are very similar ( same for me on 200m distance ) except that Acebeam is way abnormally hot just after a short time 1 min, it is extremely hot for that such small kind of time.
Convoy is cold for that time.

This Acebeam is way out of specs and it is hot like as hell, ok I know it is not only this light and there is a lot of more, but I think for this kind of company like is Acebeam this is unacceptable.
Nitecore also disappoint, much less branded flashlights have more precise specifications..

Question is, this branded flashlight manufacturers mush have an integrating sphere and must do a mesurements for light that they produce, of course I do not expecting that if light is rated on 1500 lm all lights that they produce be 1500.00 lm.. it is normal that there will be a little tolerance, but this so much less than it is writing I can’t understand what they do here and why not write a realistic numbers..

I think you will find a lot of it is marketing. The FT02s astrolux is rated at 11,000 lumens where the mateminco equivalent is 13,500. This is by the same manufacturer. I don’t think the numbers are to be taken 100 percent seriously.

Yeah and Astrolux numbers are historically inflated to begin with. But he was talking about brands that are supposedly more reputable, Acebeam and Nitecore.

Exactly that. Manufacturers that are top notch in this field, and that are very expensive.
I do not complain if Ultrafire or Trustfire or some other write things out of specification.
But this one companies that have all equipment for measuring and testing, I can’t get the point why they are doing that, that is not thing that no one can check.
Sofirn for example have much more precisely specification from this ones, and it is 3 times or more cheaper..
