Unit for luminous emittance?

For both illuminance and luminous emittance, the SI unit is lm/m². But to my knowledge, lx=lm/m2 is used for illuminance only. See e.g. [1] and [2] — Preceding unsigned comment added by Wassermaus (talk • contribs) 15:26, 17 November 2019 (UTC)

Yes, after your edit today I did some quick searching myself and found other sources that suggested the same thing. I removed the section on luminous emittance altogether, since it is no longer relevant to the topic of the article.--Srleffler (talk) 22:01, 30 November 2019 (UTC)

starlight lux rating errors?

the magnitude-0 star gives 2.08 microlux while magnitude-6 give 8 nanolux, according to the page. probably should be the other way around. i won't switch them around myself because i don't know whether the resulting values would be correct either Gridzbispudvetch (talk) —Preceding undated comment added 04:01, 29 November 2019 (UTC)

See Apparent magnitude. Larger magnitude means a dimmer star.--Srleffler (talk) 05:32, 29 November 2019 (UTC)

Kudos to the editors

This article is awesome. Congrats to the editors! Now I finally understand what light bulb I need for my office. Don Ema Valecirro (talk) 07:08, 26 April 2020 (UTC)

Relationship of lux and nit

The article should contain a few worked examples of the relationship between lux and nit in a few common situations, such as maybe a glowing sphere, surround lighting, the sun, a piece of paper, and so on. We got light source A, this emits so-and-so-much light, of which this much reaches object B which in turn itself becomes a light source of such-and-such brightness. I think it would help a great deal for conceptual understanding. — Preceding unsigned comment added by 77.61.180.106 (talk) 13:00, 1 October 2021 (UTC)

That should probably be in Luminance or Illuminance rather than here. The Luminance article has a section on the relationship between the two already.--Srleffler (talk) 02:04, 4 October 2021 (UTC)

Wrong Units being Used

Paul Schlyter's work is not in lux, but in nit. The numbers are being carried over without any conversion. 2600:1700:9B10:4070:536:5E75:B19:5903 (talk) 05:38, 11 July 2024 (UTC)

The cited page says explicitly that the numbers are in lux.--Srleffler (talk) 21:43, 20 July 2024 (UTC)
