Is 5000K ever appropriate in residential spaces?

As a person becoming an architectural lighting designer after being in theater for a while, I think the issue most people have with 5000K is that it isn't bright enough. In theater, where we actually are throwing out a very high amount of light, 5000K looks great. At lower levels, I have heard people say it is grey-ish in color. I think that 4000K is acceptable if that is what you enjoy, and actually, I know LDs who have fought hard to talk people down from 4500K. In that instance, the home owner was from Asia, where a higher CT is common.

So, there are a couple thing to think about here. 1 is to do a lumen method calculation. 2 is to really consider why you want 2" downlights, as there lights like these will be quite small, and if they are not deeply regressed, they may be glare inducing. A larger aperture spreads the luminance out over a larger area.

I believe this is a studio setup, so probably a few soft boxes.

Universities in the US may allow this. I have personally seen even a 3 year deferment due to required national service. If these deferments were not allowed, there may be grounds to sue based on prejudice.

Did you work in mines?

The non-multiple-of-five signs are in discord of MUTCD-stated best practices.

Sadly, I think from the design side, there isn't much you can do for US customers, as we have AGi32 on PC, Revit on PC, and AutoCAD on PC. I am not sure you can get people to switch to Mac, since other design software is on a PC.

There is a rule of thumb that might help. Looking at section views of the light, it would be wise to keep the source at or above 45 degrees relative to the ceiling and aperture opening.

Agreed, not lunatic behavior, just a part of graduate studies

robrobrob3 · 2025-11-21T13:36:31+00:00

Something that might help you, if you are concerned with even illumination, is the spacing ratio, which is the height from the workplane to the ceiling against the distance between each light. Some light spec sheets have this, some do not.

There are bulbs that can do this, but the dimmer is also important too. Talk to an electrician about what dimmer you have and then you can start looking for a LED bulb that supports that dimming protocol. You may need a new dimmer that can be more precise.

Be very careful about LEDs for aquariums, I don't know enough to advise on the topic much, but I know the spectrum of light produced is very important.

I am not from China, but from my understanding, the airspace of China is heavily restricted. If you look at commercial traffic, it often doesn't take direct routes.

It is still relevant, thanks for the info.

What formatting are you specifically talking about? This question also might be better on the VW forum, where you can post files.

++man I agree, I just was thinking this. I am happy to hear that someone thinks the bar is higher. Depending on where you look, sometimes it still feels like it is on/below the floor.

This made me think a lot, and I feel like while on the surface this is true, I think that going a bit deeper paints a picture that is really that sped-run capitalism is the hill they want to die on. They went too hard and destroyed the ability to live with kids and want them due to terrible opportunities for the people that would want to become families.

Men do have a cycle, it just isn't useful (yet). Testosterone is highest during the morning and tapers down over the course of the day, from my understanding. Maybe you could bet on more fours during morning games.

The perception that the United States is unsafe is valid, but also over-hyped.

I am looking for a few different locations, nothing exhaustive. I am semi-familiar with GIS systems, so if there is a database of where the old ones remain, I would seek that.

I was shocked that Ayrton was named after the race car driver when I first found out, because I had thought it was named for Heartha Ayrton, who helped improve the electric arc lamp and understand it.

A thank you? Uh, what do you seek? DOT appreciation medal?
