Bullshit units of measure

Just to chime in: it is a reason why professionals considering Miele(to quote some commercial from them: "use now, and 30years from now the same vacuum" - true, as I saw in quite a few places) first in residential areas.
And honestly, I'm surprised that so far nobody mentioned the brand.

AW(air watts) might be another way how to describe 1% power efficiency


--- Quote from: james_s on October 13, 2022, 07:20:30 am ---Many of the flashlights are greatly exagerated, however it would not take multiple kW of LEDs to reach those numbers. A 1kW metal halide lamp of the sort used to illuminate parking lots and sports fields is about 125,000 lumens. Recently these are getting replaced by LED lights that consume about 1/3 that.

1/3 may come from reduced light output

L/W (lumen watts) is another . if remember correctly incandescent power efficiency ~0,5% and LED ~10%

Do they plaster their marketing with bullshit units? Well, then :)

hm.. that's odd, I remember reading all about how it was standard brushless tech with a coat of paint.
I wonder if I was tricked with a fake article or just had my wire crossed on that one.

In any case, it seems i was wrong about that one.

--- End quote ---


Yeah, but not by the measures that matter to me.
A product could be amazing at all it's intended use case while still being produced or marketed through dishonest practices.

For me a product is only "good" if its a good product to use AND the company that created it acts in a positive way.
(Or usually just not in a grossly negative way.)

--- End quote ---

I think that is really a matter of perspective and wealth, Apple and Dyson both make expensive products and I think most people would agree with that. I don't know much about the longevity of Dyson products which is very important when analyzing value for money. But it's very clear Apple products are engineered with zero effort to keep them running past the warrantee period or next product release.
