2700 K is "warm" and comparable to candle light and fires used by our ancestors, also incandescent tungsten lamps. So most suitable for our interior living spaces. I put some 5000 K lamps in an office to show my architect partners how I could change the hue of their wall paint. Very good introduction to this topic. As a retired electrical engineer nothing irks me more than to go into a commercial space and see different color temperature lamps.

I'm doing my apprenticeship in school for 8 weeks and i've really found a lot of your videos helpful, even though a lot of this stuff i have already read or encountered through classes
in different courses i have taken in order to become an electrician i also decided to try to learn a bit more on my free time because i wanna enjoy working in this trade for as long as possible so thank you my brother!

[DanielFreeman-oc]

Dustin you’re a wealth of knowledge and a true role model to me in the industry. The content you put out is like no one else. I like how you get into the science of our field. You truely go above and beyond. Thanks for all you do for us!

[NeedtoSpeak]

Fantastic overview of what is an extremely confusing consumer issue.

[bluej]

I went from 4k to 2.7k and absolutely love it. Fyi for fog lights in a car always go 2.7k or even lower. Won't bounce off fog.

[rogerpenske]

I remember the old “green lights” on Lower Wacker Drive in Chicago when I was a little kid. Kelly green. Hizzonor da Honorable Richard J Daley, mayor at the time.

[timothysayer]

I didn't know much about lighting until now. Thanks

[poolsdoc]

And it gets more interesting Dustin, the actual color that we see in objects are not their true color, is just the color that escapes with the light bouncing back and into our eyes🧐

[raymond]

Very helpful and interested information, And those are the information most people tend to overlook, most people will just buy a light bulb off it's wattage.

[lyfandeth]

I'm very aware of colors and color temperature. And I keep my Kindle set for a beige background with blueblocker on. But it still amazes me how often I have to check that it is beige, because it very quickly comes to be seen as white.

[davidm]

My mom hates LEDs because the old ones didn't have 17k lights (but now they do), but I really like my lights to be as bright as possible, because if I want light, I want to see every detail.
I'm glad to see something that breaks this kind of stuff down.

[sween]

The colour you choose will depend where you live, if you live in a cold country you'd want warm white and if you live in a hot country you'd want cold light. Fun fact about the low sodium lights is that I observatories like them as they are only one band of light, which with a bit of science and computers is very easy to block out so it doesn't interfere with their work

[itzNickyJayBeats]

The kelvin scale with lighting is badass. I want to find the perfect wall colors for the perfect light kelvin temperatures! I am on a mission! lol

[dustind]

In a lab or shop that requires high color rendering, I recommend 50k. In an office setting, 40k, and at home in living rooms and bedrooms, i recommend 35k or lower. Commercial lighting professional for 21 years.

[youdontknowme]

Mmmmm, yes... I geek-out on lighting. 😊
I use 5000K for task and work areas
(and mandatory high-CRI in kitchen---low-CRI makes some foods look weird)
and 2700K for casual, accent, everywhere else...
I use harsh 6500K in outdoor motion securiry lighting just to be a jerk LOL, hey, it seems to work 😏

[richardrogue]

I was literally just learning about this in my apprenticeship class lol

[vgupta]

Would have been great to see both lights switched on and see the color differences

[rogerpenske]

I remember when my buddy, and boss, Boogie, got a high pressure sodium light from Kennedy-King College (One of the city colleges of Chicago), and tried to grow reefer in one of the rooms in my basement! That was a long time ago before it was legal!

[joelboutier]

Most all of my customers never choose past 3500k-4000k. I don't know many residential environments where people are choosing beyond soft or warm white other than maybe their exterior flood lights. Not many people like bright white or daylight. It's way too aggressive for most people's taste. Above that 4000k range, it gives hospital or office building vibes.

[JCWren]

I've been trying to find some high bay lights for my shop that are in the 4K to 5K range with a CRI of 90+ and they either don't exist or they're insanely expensive. What I'd really like is remote dimming AND remote color temperature setting via a wired interface. You can find a few lights that have adjustable color temperature via WiFi, but that's always a pain because it's bound to your phone or tablet and anyone who just happens to be in the shop can't change the color temperature.
